How to use BeanUtils.copyProperties?

How to use BeanUtils.copyProperties? - java

I am trying to copy properties from one bean to another. Here are the signature of two beans:

I am trying to copy properties from SearchContent to Content as:
Content content = new Content();
Converter converter = new DateConverter(null);
BeanUtilsBean beanUtilsBean = BeanUtilsBean.getInstance();
beanUtilsBean.getConvertUtils().register(converter, Date.class);
BeanUtils.copyProperties(searchContent, content);
System.out.println(searchContent);
System.out.println(content);
The Sysout is printing:
com.mhis.dam.service.search.bean.SearchContent[id=52906,docName=MHIS043570,docType=Images,docTitle=preview_1_8,docAuthor=sysadmin,securityGroup=Internal,docAccount=WF/017/DAM/000,revLabel=1,profile=DAMMedia,workflowStage=com.mhis.dam.generic.bean.LabelValueBean[label=Published,value=published],createDate=Fri Oct 18 15:30:35 IST 2013,inDate=Fri Oct 18 15:30:35 IST 2013,originalName=Vintage 2004 Gift Box & Bottle Black - hires.jpg,format=image/jpeg,extension=jpg,fileSize=2106898,author=Arjan,entity=com.mhis.dam.generic.bean.LabelValueBean[label=Dom Perignon,value=WF/017/DAM],brand=com.mhis.dam.generic.bean.LabelValueBean[label=Dom Perignon,value=WF/017/DAM/001],product=com.mhis.dam.generic.bean.LabelValueBean[label=Blanc,value=17_1_blanc],collection=com.mhis.dam.generic.bean.LabelValueBean[label=Pack shot,value=pack_shot_dp],subCollection=com.mhis.dam.generic.bean.LabelValueBean[label=Bottle shot,value=ps_bottle_dp],description=preview_1,program=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],vintage=,model=,restrictedZone=,event=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],language=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],geographicLocation=,watermark=,pageNumber=0,summary=,agentName=,commissionedByName=Nicolas,commissionedByDepartment=,bestOf=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=0],mediaLocation=,fullRights=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=1],mediaUsage=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=],rightsEndDate=<null>,geographicRights=,evinConformity=com.mhis.dam.generic.bean.LabelValueBean[label=<null>,value=2],contactReference=,publicationScope=com.mhis.dam.generic.bean.LabelValueBean[label=Full public usage,value=fullPublic],rightsComment=]

It is obvious to have null values for selected and renditionInfoFetched fields of the class Content, since they are not present in SearchContent but you can see all the other properties of Content is null. I am unable to find what I am doing wrong!
Any pointer would be very helpful.

There are two BeanUtils.copyProperties(parameter1, parameter2) in Java.
One is
org.apache.commons.beanutils.BeanUtils.copyProperties(Object dest,
Object orig)
Another is
org.springframework.beans.BeanUtils.copyProperties(Object source,
Object target)
Pay attention to the opposite position of parameters.

If you want to copy from searchContent to content, then code should be as follows
BeanUtils.copyProperties(content, searchContent);
You need to reverse the parameters as above in your code.
From API,
public static void copyProperties(Object dest, Object orig)
throws IllegalAccessException,
InvocationTargetException)
Parameters:
dest - Destination bean whose properties are modified
orig - Origin bean whose properties are retrieved

As you can see in the below source code, BeanUtils.copyProperties internally uses reflection and there's additional internal cache lookup steps as well which is going to add cost wrt performance
private static void copyProperties(Object source, Object target, #Nullable Class<?> editable,
#Nullable String... ignoreProperties) throws BeansException {
Assert.notNull(source, "Source must not be null");
Assert.notNull(target, "Target must not be null");
Class<?> actualEditable = target.getClass();
if (editable != null) {
if (!editable.isInstance(target)) {
throw new IllegalArgumentException("Target class [" + target.getClass().getName() +
"] not assignable to Editable class [" + editable.getName() + "]");
}
actualEditable = editable;
}
**PropertyDescriptor[] targetPds = getPropertyDescriptors(actualEditable);**
List<String> ignoreList = (ignoreProperties != null ? Arrays.asList(ignoreProperties) : null);
for (PropertyDescriptor targetPd : targetPds) {
Method writeMethod = targetPd.getWriteMethod();
if (writeMethod != null && (ignoreList == null || !ignoreList.contains(targetPd.getName()))) {
PropertyDescriptor sourcePd = getPropertyDescriptor(source.getClass(), targetPd.getName());
if (sourcePd != null) {
Method readMethod = sourcePd.getReadMethod();
if (readMethod != null &&
ClassUtils.isAssignable(writeMethod.getParameterTypes()[0], readMethod.getReturnType())) {
try {
if (!Modifier.isPublic(readMethod.getDeclaringClass().getModifiers())) {
readMethod.setAccessible(true);
}
Object value = readMethod.invoke(source);
if (!Modifier.isPublic(writeMethod.getDeclaringClass().getModifiers())) {
writeMethod.setAccessible(true);
}
writeMethod.invoke(target, value);
}
catch (Throwable ex) {
throw new FatalBeanException(
"Could not copy property '" + targetPd.getName() + "' from source to target", ex);
}
}
}
}
}
}
So it's better to use plain setters given the cost reflection

Realm Migration is not working in Android?

I am at present working on a android chat application like whatsapp but I stuck at a situation in where Realm Migration is issue. I am not knowing so much about realm but testing it for a successful offline chat application. I am not able to use more than one model in realm because it is saying about the migrator. I tried all the ways but my migrator is not working and I also not having idea that what statements I have to use after this (schema.) statement for migrate my model according to my situations.
Here is the Code for my Realm ChatList Model:-
public class RealmChatListModel extends RealmObject {
#Index
private String userID;
private String Username;
private String Descryption;
private String phoneNo;
private String lastMessage;
private String Date;
private String ImageURI;
private long lastMessageTime;
public RealmChatListModel() {
}
public String getUserID() {
return userID;
}
public void setUserID(String userID) {
this.userID = userID;
}
public String getUsername() {
return Username;
}
public void setUsername(String username) {
Username = username;
}
public String getDescryption() {
return Descryption;
}
public void setDescryption(String descryption) {
Descryption = descryption;
}
public String getPhoneNo() {
return phoneNo;
}
public void setPhoneNo(String phoneNo) {
this.phoneNo = phoneNo;
}
public String getLastMessage() {
return lastMessage;
}
public void setLastMessage(String lastMessage) {
this.lastMessage = lastMessage;
}
public String getDate() {
return Date;
}
public void setDate(String date) {
Date = date;
}
public String getImageURI() {
return ImageURI;
}
public void setImageURI(String imageURI) {
ImageURI = imageURI;
}
public long getLastMessageTime() {
return lastMessageTime;
}
public void setLastMessageTime(long lastMessageTime) {
this.lastMessageTime = lastMessageTime;
}
}
And here is my code for realm Chat Model :-
public class RealmChat extends RealmObject {

And Here is my code for my migrator :-
public class RealmMigration implements io.realm.RealmMigration {
#Override
public void migrate(DynamicRealm realm, long oldVersion, long newVersion) {
RealmSchema schema = realm.getSchema();
// Migrate from version 0 to version 1
if (oldVersion == 0) {
schema.get("RealmChatListModel")
.addField("Username", String.class)
.addRealmListField("lastMessageTime", long.class);
oldVersion++;
}
if (oldVersion == 1) {
schema.get("RealmChat")
.addField("extactdate", Date.class)
.addRealmListField("timestamp",long.class);
}
}
public static RealmConfiguration getDefaultConfig() {
return new RealmConfiguration.Builder()
.schemaVersion(2)
.migration(new RealmMigration())
.build();
}
#Override
public int hashCode() { return RealmMigration.class.hashCode(); }
#Override
public boolean equals(Object object) { return object != null && object instanceof RealmMigration; }
}
Please Help me...................................................................................
<<<<<<<<<<<<<<<<------------------(~~~~~~~~~~~~~~~~~~~)------------------->>>>>>>>>>>>>>>>>>>>>

Yes I got it my migration is working only by a single change :-
#Override
public void migrate(DynamicRealm realm, long oldVersion, long newVersion) {
RealmSchema schema = realm.getSchema();
// Migrate from version 0 to version 1
if (oldVersion == 0) {
schema.get("RealmChatListModel")
.addField("userID", String.class, FieldAttribute.REQUIRED);
oldVersion++;
}
}
Here I removed Realm Chat from migrating the old version because it is the last model and added in realmChatListSchema that userID field is required.Noting else reqired. I am happy 🥰 🥰 🥰 .

How to only update certain fields that might already be null (using JSON patch)

I am trying to use json patch to update an object using PATCH in my app.
I want to update only 2 fields in my object and they might be null before updating.
Each time I try and update, the whole object gets updated.
How do I restrict this?
I've tried multiple ways.
#PatchMapping("/bmwsales/updateweb/{id}")
public ResponseEntity<?> updateVehicleTagWeb(#PathVariable(value="id") Integer id, #RequestBody Bmwsales v) throws JsonProcessingException{
ObjectMapper objMapper=new ObjectMapper();
JsonPatchBuilder jsonPatchBuilder=Json.createPatchBuilder();
JsonPatch jsonPatch=jsonPatchBuilder.replace("/templocation",v.getTemplocation()).replace("/rfidtag", v.getRfidtag()).build();
Bmwsales vehicle=bmwService.getVin(id).orElseThrow(ResourceNotFoundException::new);
BmwsalesUpdate veh=oMapper.asInput(vehicle);
BmwsalesUpdate vehPatched=patchHelp.patch(jsonPatch, veh, BmwsalesUpdate.class);
oMapper.update(vehicle, vehPatched);
System.out.println("the patched info is: "+vehicle.getRfidtag()+vehicle.getTemplocation());
bmwService.updateVehTag(vehicle);
return new ResponseEntity<>(HttpStatus.OK);
#Override
public void updateVehTag(Bmwsales vehicle) {
bmwsalesRepository.save(vehicle);
}

How do I update only these fields?

Your code is long one why are you code getters/setters/constructors from typing.it will get a long time to develop.
Then what you must add this dependency into your POM.xml file
<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<version>1.18.8</version>
<scope>provided</scope>
</dependency>
And adding this dependency you can generate your getters/setters and constructors from giving simple annotations like this.do not type those in your fingers.:-)
Then your code will be more easy to readable.
#Data //this will create all getters,setters,toString
#NoArgsConstructor //this will create default constructor
#AllArgsConstructor //this will create all argivements constructor
#Entity(name="bmwsales") //name means table name
public class Bmwsales implements Serializable{
#Id
#Column(name="id")
#GeneratedValue(strategy=GenerationType.IDENTITY)
private Integer id;
// like this do all your columns
#NotNull(message="customer First Name is compulsory")
#Column(name="customerfirstname")
private String customerfirstname;
//your entity mapping here etc.
}
After that, if the user does not fill the required fields that message will trigger.
And your controller class that means your endpoint calling place should use #Valid annotation to your Entity class or DTO class(you do not get DTO).
#PatchMapping("/bmwsales/updateweb/{id}")
public ResponseEntity<String> updateVehicleTagWeb(#PathVariable(value="id") Integer id, #Valid #RequestBody Bmwsales v) throws JsonProcessingException{
ObjectMapper objMapper=new ObjectMapper();
JsonPatchBuilder jsonPatchBuilder=Json.createPatchBuilder();
JsonPatch jsonPatch=jsonPatchBuilder.replace("/templocation",v.getTemplocation()).replace("/rfidtag", v.getRfidtag()).build();
Bmwsales vehicle=bmwService.getVin(id).orElseThrow(ResourceNotFoundException::new);
BmwsalesUpdate veh=oMapper.asInput(vehicle);
BmwsalesUpdate vehPatched=patchHelp.patch(jsonPatch, veh, BmwsalesUpdate.class);
oMapper.update(vehicle, vehPatched);
System.out.println("the patched info is: "+vehicle.getRfidtag()+vehicle.getTemplocation());
bmwService.updateVehTag(vehicle);
return ResponseEntity.ok("Input is valid");

The code that I use is the following:

final ProductItems categoryProducts = gson.fromJson(mMessage, ProductItems.class);
response.close();
}
catch (Exception e)
{
Log.e("Error", "Failed to upload");
e.printStackTrace();
}
However, I get the following error: GSON throwing “Expected BEGIN_OBJECT but was BEGIN_ARRAY.
I have tried to change the ProductItems class to taking an object for productbycategories but then I get the following error: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected a string but was BEGIN_OBJECT at line 1 column 2324 path $.ProductsByCategory[0].meta_data[0].value. I am now a bit confused.

The reason you get this error is that the data is not consistent with the way the POJO is generated.
This is the specific part of the data that has the issue:
"meta_data": [
{
"id": 14232,
"key": "_vc_post_settings",
"value": {
"vc_grid_id": []
}
},
{
"id": 14273,
"key": "fb_product_description",
"value": ""
},
{
"id": 14274,
"key": "fb_visibility",
"value": "1"
},
Notice how the "meta_data" field is an array of objects and that these objects contain a "value" field. The data type of the "value" varies- sometimes it's an object and other times it's a string.
One possible solution would be to change the MetaDatum class so that the value is an Object:
package com.example;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
public class MetaDatum {
...
#SerializedName("value")
#Expose
private Object value;
...
public Object getValue() {
return value;
}
public void setValue(Object value) {
this.value = value;
}
}

get values from string and copy the values to pojo properties : java

I have a string containing this values :
String verifyPaymentDetails = "{
2298597={mihpayid=403993715508098532, request_id=NULL, bank_ref_num=NULL, amt=53.77, disc=0.00, mode=CC, PG_TYPE=AXIS, card_no=512345XXXXXX2346, name_on_card=emu, udf2=0, addedon=2013-06-03 17:34:42, status=failure, unmappedstatus=failed, Merchant_UTR=NULL, Settled_At=NULL},
6503939={mihpayid=Not Found, status=Not Found}
}"
and I want to extract the values from the above string and store them like the following :
key would be 2298597 and values for the key mihpayid=403993715508098532, request_id=NULL, bank_ref_num=NULL, amt=53.77, disc=0.00, mode=CC, PG_TYPE=AXIS, card_no=512345XXXXXX2346, name_on_card=emu, udf2=0, addedon=2013-06-03 17:34:42, status=failure, unmappedstatus=failed, Merchant_UTR=NULL, Settled_At=NULL
Map<String,Item> tag = new HashMap<String,VerifyPaymentRO>();
and this is what is my VerifyPaymentRO
public class VerifyPaymentRO {
private String mihpayid;
private String request_id;
private String bank_ref_num;
private String amt;
private String disc;
private String mode;
private String PG_TYPE;
private String card_no;
private String name_on_card;
private String udf2;
private String addedon;
private String status;
private String unmappedstatus;
private String Merchant_UTR;
private String Settled_At;
public String getMihpayid() {
return mihpayid;
}
public void setMihpayid(String mihpayid) {
this.mihpayid = mihpayid;
}
public String getRequest_id() {
return request_id;
}
public void setRequest_id(String request_id) {
this.request_id = request_id;
}
public String getBank_ref_num() {
return bank_ref_num;
}
public void setBank_ref_num(String bank_ref_num) {

}

return amt;
}
public void setAmt(String amt) {
this.amt = amt;
}
public String getDisc() {
return disc;
}
public void setDisc(String disc) {
this.disc = disc;
}
public String getMode() {
return mode;
}
public void setMode(String mode) {
this.mode = mode;
}
public String getPG_TYPE() {
return PG_TYPE;
}
public void setPG_TYPE(String pG_TYPE) {
PG_TYPE = pG_TYPE;
}
public String getCard_no() {
return card_no;
}
public void setCard_no(String card_no) {
this.card_no = card_no;
}
public String getName_on_card() {
return name_on_card;
}
public void setName_on_card(String name_on_card) {
this.name_on_card = name_on_card;
}
public String getUdf2() {
return udf2;
}
public void setUdf2(String udf2) {
this.udf2 = udf2;
}
public String getAddedon() {
return addedon;
}
public void setAddedon(String addedon) {
this.addedon = addedon;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getUnmappedstatus() {
return unmappedstatus;
}
public void setUnmappedstatus(String unmappedstatus) {
this.unmappedstatus = unmappedstatus;
}
public String getMerchant_UTR() {
return Merchant_UTR;
}
public void setMerchant_UTR(String merchant_UTR) {
Merchant_UTR = merchant_UTR;
}
public String getSettled_At() {
return Settled_At;
}
public void setSettled_At(String settled_At) {
Settled_At = settled_At;
}
}
so how do get the id from the string and values for the id and copy the values to POJO and store them like id and object in a HashMap?
if there is way for this in spring also fine

Assuming it is not a JSON and you really need to do the hard work, I think the best solution is to use the combination of Rojo and BeanMap from commons-beanutils. I am also author of Rojo, so I would like to show how it could be used in this context. I wouldn't recommend direct regexp mapping by group due to dynamically changing number of pairs inside, so that's why I think the BeanMap could do a lot of work for us.
First let's update your bean with id, which will serve as a primary key:
public class VerifyPaymentRO {
private String id;
private String mihpayid;
private String request_id;
private String bank_ref_num;
private String amt;
private String disc;
private String mode;
private String PG_TYPE;
private String card_no;
private String name_on_card;
private String udf2;
private String addedon;
private String status;
private String unmappedstatus;
private String Merchant_UTR;
private String Settled_At;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getMihpayid() {
return mihpayid;
}
public void setMihpayid(String mihpayid) {
this.mihpayid = mihpayid;
}
public String getRequest_id() {
return request_id;
}
public void setRequest_id(String request_id) {
this.request_id = request_id;
}
public String getBank_ref_num() {
return bank_ref_num;
}
public void setBank_ref_num(String bank_ref_num) {
this.bank_ref_num = bank_ref_num;
}
public String getAmt() {
return amt;
}
public void setAmt(String amt) {
this.amt = amt;
}
public String getDisc() {
return disc;
}
public void setDisc(String disc) {
this.disc = disc;
}
public String getMode() {
return mode;
}
public void setMode(String mode) {
this.mode = mode;
}
public String getPG_TYPE() {
return PG_TYPE;
}
public void setPG_TYPE(String PG_TYPE) {
this.PG_TYPE = PG_TYPE;
}
public String getCard_no() {
return card_no;
}
public void setCard_no(String card_no) {
this.card_no = card_no;
}
public String getName_on_card() {
return name_on_card;
}
public void setName_on_card(String name_on_card) {
this.name_on_card = name_on_card;
}
public String getUdf2() {
return udf2;
}
public void setUdf2(String udf2) {
this.udf2 = udf2;
}
public String getAddedon() {
return addedon;
}
public void setAddedon(String addedon) {
this.addedon = addedon;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public String getUnmappedstatus() {
return unmappedstatus;
}
public void setUnmappedstatus(String unmappedstatus) {
this.unmappedstatus = unmappedstatus;
}
public String getMerchant_UTR() {
return Merchant_UTR;
}
public void setMerchant_UTR(String merchant_UTR) {
Merchant_UTR = merchant_UTR;
}
public String getSettled_At() {
return Settled_At;
}
public void setSettled_At(String settled_At) {
Settled_At = settled_At;
}
}
Now the working example could be as follows:
public class VerifyPaymentExample {
public static void main(String[] args) {
String verifyPaymentDetails = "{" +
"2298597={mihpayid=403993715508098532, request_id=NULL, bank_ref_num=NULL, amt=53.77, disc=0.00, mode=CC, PG_TYPE=AXIS, card_no=512345XXXXXX2346, name_on_card=emu, udf2=0, addedon=2013-06-03 17:34:42, status=failure, unmappedstatus=failed, Merchant_UTR=NULL, Settled_At=NULL}," +
"6503939={mihpayid=Not Found, status=Not Found}" +
"}";
Map<String, VerifyPaymentRO> result = Rojo.asMap("(\\d+)=\\{(.+?)\\}", verifyPaymentDetails)
.entrySet()
.stream()
.map(e -> toBean(e))
.collect(Collectors.toMap(VerifyPaymentRO::getId, Function.identity()));
}
public static VerifyPaymentRO toBean(Map.Entry<String,String> entry) {
VerifyPaymentRO bean = new VerifyPaymentRO();
bean.setId(entry.getKey());
BeanMap beanMap = new BeanMap(bean);
Rojo.asMap("(\\w.+?)=([^,]+)", entry.getValue())
.forEach( (key, value) -> {
//Some additional mapping is required due to non-standard naming
if ("Settled_At".equals(key)) {
beanMap.put("settled_At", value);
} else if ("Merchant_UTR".equals(key)) {
beanMap.put("merchant_UTR", value);
} else {
beanMap.put(key, value);
}
});
return bean;
}
}
If you run the code and look into result, you should have exactly what you want.

Hibernate JPA searching two joined tables

I am pretty new to Hibernate and JPA implementation in Spring, so basically have set up a MySQL 5 database which maps to the domain objects below.

}

You need two criteria: criteria on the Company_Details class
And criteria on the Product_Details class
Then
Criteria crit1 = session.createCriteria(Company_Details.class);
crit1.add(restriction)
Criteria crit2 = crit1.createCriteria("products");
crit2.add(restriction)
// Then query crit1
List results = crit1.list();
