How to pass array of string in insert query in ibatis?

How to pass array of string in insert query in ibatis? - java

How to pass array of string in insert query statement in ibatis. On passing string array as parameter it is giving me this exception of ibatis -
Can't infer the SQL type to use for an instance of [Ljava.lang.String;. Use setObject() with an explicit Types value to specify the type to use.
How to solve this error ?
My method is -
public void insertCampaignData(String campaignData, ObjectMapper jsonObjMapper) {
Campaign campaign = null;
SqlSession session = null;
IfrmCreateCampaign createCampaign = null;
try {
campaign = jsonObjMapper.readValue(campaignData,Campaign.class);
session = DBConnectionFactory.getNewSession();
createCampaign = session.getMapper(IfrmCreateCampaign.class);
createCampaign.insertCampaignData(campaign);
} catch (Exception e) {
e.printStackTrace();
} finally {
session.close();
}

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 🥰 🥰 🥰 .

On the other hand I have a method call setListToPOJO
public class Utility{
public static void setListToPOJO(List<String> objList, HealthDetails healthDetails){
Methods[] methods = healthDetails.getClass().getDeclaredMethods();
int i = 0;
for(Method method : methods){
if(method.getName().startsWith("set"){
method.invoke(healthDetails, objList.get(i++));
}
}
//include all the try catch methods IllegalArgumentException /
//IllegalArgumentException / InvocationTargetException
}
however i caught an argumentTypeMissmatch
Any Idea how do i solve this without modifying the access Field?
this is the method use to make it work the main class
public class RunMethod{
public static void main(String[] args){
List<String> data = Arrays.asList("object0", "object1", "object2", "object3", "object4", "object5", "object6", "object7", "object8", "object9", "object10", "object11", "object12", "object13", "object14", "object15", "object16", "object17", "object18", "object19", "object20", "object21", "object22", "object23", "object24", "object25", "object26", "object27", "object28", "object29", "object30", "object31", "object32", "object33", "object34", "object35", "object36", "object37", "object38", "object39", "object40", "object41", "object42", "object43", "object44", "object45", "object46", "object47", "object48", "object49", "object50", "object51", "object52", "object53", "object54", "object55", "object56", "object57", "object58", "object59", "object60", "object61", "object62", "object63", "object64", "object65", "object66", "object67", "object68", "object69", "object70", "object71", "object72", "object73", "object74", "object75", "object76", "object77", "object78", "object79", "object80", "object81", "object82", "object83", "object84", "object85", "object86", "object87", "object88", "object89", "object90", "object91", "object92", "object93", "object94", "object95", "object96", "object97", "object98", "object99", "object100", "object101", "object102", "object103", "object104", "object105", "object106", "object107", "object108", "object109", "object110", "object111", "object112", "object113", "object114", "object115", "object116", "object117", "object118", "object119");
HealthDeatils healthDetails = new HealthDetails();
Utility.setListToPOJO(data,healthDetails);
}
}
Below is the output
Error Message (Edited):
java.lang.IllegalArgumentException: argument type mismatch
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
atsun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)

at java.lang.reflect.Method.invoke(Method.java:592)

The cause is that the parameter you passed, objList.get(i++) is not the type the method you invoke required.
modify you code to
for(Method method : methods){
String value = objList.get(i);
try {
if(method.getName().startsWith("set"){
method.invoke(healthDetails, value);
i++;
}
} catch (Exception e) {
e.printStackTrace();
System.out.println("Value is: " + value); // show which value is wrong
}
}
This would check which value type is wrong.
On the other hand, for the wrong order of methods. I suggest you change objList from List<String> to Map<String, Obj>, the key is the name of the method you want to invoke, like Id, Name. Then you invoke it by just add set in front of it.
for (Map.Entry<String, String> entry : map.entrySet())
{
Object value = entry.getValue();
Method method = healthDetails.getClass().getDeclaredMethod("set"+entry.getKey(), value.getClass());
method.invoke(healthDetails, value);
}

Your HealthDetails class have 124 properties and 124 setter methods but you are populating data list with only 120 elements causing ArrayIndexOutOfBoundsException while calling the setter methods through reflection.
If we provide arguments for all the setter methods in that list your code will work without any issue.
Below is the working modified code:
public class RunMethod {
public static void main(String[] args) {
List<String> data = Arrays.asList("id", "name", "age", "height", " object0", "object1", "object2", "object3", "object4", "object5", "object6", "object7", "object8", "object9", "object10", "object11", "object12", "object13", "object14", "object15", "object16", "object17", "object18", "object19", "object20", "object21", "object22", "object23", "object24", "object25", "object26", "object27", "object28", "object29", "object30", "object31", "object32", "object33", "object34", "object35", "object36", "object37", "object38", "object39", "object40", "object41", "object42", "object43", "object44", "object45", "object46", "object47", "object48", "object49", "object50", "object51", "object52", "object53", "object54", "object55", "object56", "object57", "object58", "object59", "object60", "object61", "object62", "object63", "object64", "object65", "object66", "object67", "object68", "object69", "object70", "object71", "object72", "object73", "object74", "object75", "object76", "object77", "object78", "object79", "object80", "object81", "object82", "object83", "object84", "object85", "object86", "object87", "object88", "object89", "object90", "object91", "object92", "object93", "object94", "object95", "object96", "object97", "object98", "object99", "object100", "object101", "object102", "object103", "object104", "object105", "object106", "object107", "object108", "object109", "object110", "object111", "object112", "object113", "object114", "object115", "object116", "object117", "object118", "object119");
HealthDetails healthDetails = new HealthDetails();
Utility.setListToPOJO(data, healthDetails);
}
}
Utility Class
public class Utility{
public static void setListToPOJO(List objList, HealthDetails healthDetails) {
System.out.println(objList.size());
Method[] methods = healthDetails.getClass().getDeclaredMethods();
System.out.println("methods array size " +methods.length);
int i = 0;
for (Method method : methods) {
if (method.getName().startsWith("set")) {
System.out.println(method.getName());
try {
method.invoke(healthDetails, objList.get(i++));
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
}
}
}

A different approach.
Currently, your code reads:
Methods[] methods = healthDetails.getClass().getDeclaredMethods();
int i = 0;
for(Method method : methods){
if(method.getName().startsWith("set"){
method.invoke(healthDetails, objList.get(i++));
}
}
The implicit assumption here is: the setter methods returned by getDeclaredMethods() are in the same order as your parameters (List<String> objList).
First of all, that assumption is wrong. There is no guaranteed order in that array.
But beyond that: when you know the order of elements in your list you simply don't need to use reflection at all.
You just do:
for (int i=0; i < objList.size(); i++) {
String parm = objList.get(i);
switch (i) {
case 0: healthDetails.setId(parm); break;
case 1: healthDetails.set...(parm); break;
and so on.
The point is, as stated multiple times: using a flat list means that you (somehow) must know in which order the arguments come in. And then you can simply use that order to determine the required setter method.
In other words: the code example you are showing implies that you do not need to use reflection to solve this problem. At all. Your idea to use reflection only buys you complexity, nothing else.
( of course: when the input would be a Map<String, String> that provided the field names, things would be different. but as long as you use a list with a fixed order, there is no need and point using reflection! )
Given the update, the only real answer there is: don't use 100+ fields named data1, data2, ... that is what arrays/list are for.

Spark: Mapping RDD to RDD returning nullpointer Exception

In my logic, I am attempting to map a JDBCRDD - TopologyRDD over to a JavaBean of JavaRDD.
TopologyRDD.count() returns the CORRECT number of rows, so I know the data was loaded in correctly. I also mapped TopologyRDD to a List just to confirm the data was loaded in, and it loaded in the data just fine.
Problem: When mapping TopologyRDD to MODEL_TOPOLOGYRDD, the MODEL_TOPOLOGYRDD.count() action is returning a nullpointer exception error.

The only problem I can see with this code is if any line2[i] are null.
And if(line2[i].toString() == null) won't work because toString() never returns null for the Object class.
I see that you want any null values to become empty strings, so try this as your for-loop instead
for(int i = 0; i < line2.length; i++){
line2[i] = (line2[i] == null) ? "" : String.valueOf(line2[i]);
}
Note the use of String.valueOf, which altogether avoids the NullPointerException when trying to get the String value of objects.

} catch (Exception e) {
List<TblPemohon> ltp = new ArrayList<TblPemohon>();
ltp.add(new TblPemohon(e.getMessage()));
return ltp;
} finally {
db.close();
}
}

Your TblPemohon class only have non-argument constructor, but you tried to create it with a constructor that takes one string here:
ltp.add(new TblPemohon(e.getMessage()));
You need to either add a constructor that take one string, or use the non-argument constructor

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.
I am trying to search for Location on the Company_Details table but I can't figure out how to search the class Product_Details for Product_Name at the same time
If anyone could help that would be great.

#Service

#PersistenceContext
EntityManager em;
#Transactional
public List<Company_Details> search(Search search) {
LOG.info("Entering search method");
CriteriaBuilder builder = em.getCriteriaBuilder();
CriteriaQuery<Company_Details> c = builder.createQuery(Company_Details.class);
Root<Company_Details> companyRoot = c.from(Company_Details.class);
c.select(companyRoot);
c.where(builder.equal(companyRoot.get("County"),search.getLocation()));
return em.createQuery(c).getResultList();
}
}

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();
