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");

(Parse-SDK) How to access List<ParseObject> from another ParseObject?

Follow this reference
we do not send the nested ParseObject's full data to cloud code. In order to get the data of the nested ParseObject, you have to do a query or fetch. The result you get from cloud code is pretty similar to the result you get from ParseQuery. We represent nested ParseObject as pointer and you have to fetch or query it in order to use it.

Sort Array list using POJO class with particular status [duplicate]

This question already has answers here:
Sort ArrayList of custom Objects by property

Closed 5 years ago.
I have status like "In consultation","Waiting in Queue". all the data coming from json API and add all that data into array list using Pojo class.then how to sort this array list by Consultation status.

public int compare(final Patient_Get_Set object1, final Patient_Get_Set object2) {
List<String> statusList = new ArrayList();
statusList.add("consultation");statusList.add("queue"); statusList.add("waiting");
return new Integer(statusList.indexOf(object1.getConsultation_status())).compareTo(new Integer(statusList.indexOf(object2.getConsultation_status())));
}
});
add elements in statusList in same order in which order you want pojo class to be sorted.

You can use Collections to sort your array list objects.
for example your list as below.
ArrayList<Patient> list = new ArrayList<Patient>();
Then you can sort list using below code.
Collections.sort(list, new Comparator<Patient>() {
#Override
public int compare(final Patient object1, final Patient object2) {
return object1.getConsultation_status().compareTo(object2.getConsultation_status());
}
});
OR
If you are using Java version 1.8 then you can sort list using below code.
list.stream()
.sorted((object1, object2) -> object1.getConsultation_status().compareTo(object2.getConsultation_status()));

import static java.util.Comparator.comparing;
Collections.sort(list, comparing(MyObject::getStartDate));
compare data with comparing in java8 follow http://docs.oracle.com/javase/6/docs/api/java/lang/Comparable.html

how to use Parcelable for custom type objects/variable in a class (Android)

I have make a class which has a custom class object/variable and i want to make this class parcelable for passing it in to the intend so that i receive the reponse in next activity
MORE DETAILED
I Have class first ie
public class Data implements Parcelable{
#SerializedName("barlist")
Bar bar_list[];
public Bar[] getBarLst() {
return bar_list;
}
public void setBarLst(Bar lst[]) {
this.bar_list = lst;
}
#Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int flags) {
parcel.writeParcelableArray(bar_list, Parcelable.PARCELABLE_WRITE_RETURN_VALUE);
}
public static final Parcelable.Creator<Data> CREATOR = new Creator<Data>() {
public Data createFromParcel(Parcel source) {
Data data = new Data();
data.bar_list = (Bar[]) source.readParcelableArray(this.getClass().getClassLoader());
return data;
}
#Override
public Data[] newArray(int size) {
// TODO Auto-generated method stub
return new Data[size];
}
};
}
In the above class i have a custom type object/variable ie of type Bar
and my next class is ::
public class Bar implements Parcelable{
#SerializedName("name")
String Name;
#SerializedName("sex")
String sex;
#SerializedName("type")
String type;
#SerializedName("userid")
String userId;
#SerializedName("contactno")
String ContactNo;
#SerializedName("zipcode")
String zipCode;
#SerializedName("address")
String Address;
#SerializedName("email")
String Email;
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getContactNo() {
return ContactNo;
}
public void setContactNo(String contactNo) {
ContactNo = contactNo;
}
public String getZipCode() {
return zipCode;
}
public void setZipCode(String zipCode) {
this.zipCode = zipCode;
}
public String getAddress() {
return Address;
}
public void setAddress(String address) {
Address = address;
}
public String getEmail() {
return Email;
}
public void setEmail(String email) {
Email = email;
}
#Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
#Override
public void writeToParcel(Parcel parcel, int flags) {
parcel.writeString(Name);
parcel.writeString(sex);
parcel.writeString(type);
parcel.writeString(userId);
parcel.writeString(ContactNo);
parcel.writeString(zipCode);
parcel.writeString(Address);
parcel.writeString(Email);
}
public static final Parcelable.Creator<Bar> CREATOR = new Creator<Bar>() {
public Bar createFromParcel(Parcel source) {
Bar barlst = new Bar();
barlst.Name = source.readString();
barlst.sex = source.readString();
barlst.ContactNo = source.readString();
barlst.type = source.readString();
barlst.userId = source.readString();
barlst.zipCode = source.readString();
barlst.Address = source.readString();
barlst.Email = source.readString();
return barlst;
}
#Override
public Bar[] newArray(int size) {
// TODO Auto-generated method stub
return new Bar[size];
}
};
}
I want to make a data class (first class) object be parcelable so in my first activity i did some this like this
EmptyRequest empt = new EmptyRequest();
Data responsestr = userManager.getMainMenuItems(empt,"url","Post","getBarList");
Intent myintent = new Intent(MainMenuPageActivity.this, BarListPageActivity.class);
Bundle mbundle = new Bundle();
mbundle.putParcelable("BARLIST", responsestr);
myintent.putExtras(mbundle);
startActivity(myintent);
till here my code worked fine and i kept the responsestr of type data into the parcelable
and in my next acitivity i tried to fetch data object like this
Data responseStr = (Response)getIntent().getParcelableExtra("BARLIST");
to fetch the object of type data but this didnt work and give exception the second activity class not found but my debugger reaches in the second activity.
Thanks in advance....

use
getIntent().getExtras().getParcelableExtra("BARLIST");

JSON to Java Mapping Help - Nested Collection

I'm trying to figure out a way to transform this JSON String into a Java object graph but I'm unable to do so. Below, I've inserted my JSON String, and my two classes. I've verified that its a valid json structure. I've been trying googles api (http://sites.google.com/site/gson/gson-user-guide) but it doesn't map the nested Photo Collection. Any ideas or alternate libraries?
{"photos":{"page":1,"pages":73514,"perpage":50,"total":"3675674","photo":[{"id":"5516612975","owner":"23723942#N07","secret":"b8fb1fda57","server":"5213","farm":6,"title":"P3100006.JPG","ispublic":1,"isfriend":0,"isfamily":0},{"id":"5516449299","owner":"81031835#N00","secret":"67b56722da","server":"5171","farm":6,"title":"Kaiser Boys Volleyball","ispublic":1,"isfriend":0,"isfamily":0}]},"stat":"ok"}

Use Jackson. It'll take care of converting to and from JSON. It provides multiple ways of approaching conversion, and is well-integrated with frameworks like Spring. Definitely one to know.
