POJO class with Constructor for the POST request body which has nested JSON

I want to create a POJO class with Constructor for the POST request body which has nested JSON, But I am not sure how to call JSONArray inside it?
PS: I do not want to set data using the setter method, I want to use Constructor for setting the data.
Here is the JSON:
{
"FirstName": "test",
"LastName": "account",
"PASSWORD": "Password123*",
"Email": [
{
"TYPE": "Primary",
"VALUE": "arpitay6#mail7.io"
}
]}
POJO I've created -
import java.util.List;
public class PostAccountCreateAPI {
private List <Email> email;
private String password;
private String firstname;
private String lastname;
public PostAccountCreateAPI(List<Email> email, String password, String firstname, String lastname) {
this.email = email;
this.password = password;
this.firstname = firstname;
this.lastname = lastname;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public List<Email> getEmail() {
return email;
}
public void setEmail(List<Email> email) {
this.email = email;
}
}
package pojo;
public class Email {
private String type;
private String value;
public Email(String type, String value) {
this.type = type;
this.value = value;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
In the main method, I am calling POJO using -
PostAccountCreateAPI PostAccountCreateAPIPayLoad = new PostAccountCreateAPI("pri#mail7.io", "P#$$w0rd", "arpita", "garg");
But It is not working. Can anyone please suggest how to do this?

Ok....Here I am Giving a complete example:
The PostAccountCreateApi class:
import java.util.List;
public class PostAccountCreateAPI{
private String FirstName;
private String LastName;
private String PASSWORD;
private List<Email> Email;
public PostAccountCreateAPI(){}
public PostAccountCreateAPI(String FirstName, String LastName, String PASSWORD, List<Email> Email){
this.FirstName = FirstName;
this.LastName = LastName;
this.PASSWORD = PASSWORD;
this.Email = Email;
}
public void setFirstName(String FirstName){
this.FirstName = FirstName;
}
public String getFirstName(){
return this.FirstName;
}
public void setLastName(String LastName){
this.LastName = LastName;
}
public String getLastName(){
return this.LastName;
}
public void setPASSWORD(String PASSWORD){
this.PASSWORD = PASSWORD;
}
public String getPASSWORD(){
return this.PASSWORD;
}
public void setEmail(List<Email> Email){
this.Email = Email;
}
public List<Email> getEmail(){
return this.Email;
}
}
The Email Class:
public class Email {
String TYPE;
String VALUE;
public Email() {
}
public Email(String TYPE, String VALUE) {
this.TYPE = TYPE;
this.VALUE = VALUE;
}
public void setTYPE(String TYPE) {
this.TYPE = TYPE;
}
public String getTYPE() {
return this.TYPE;
}
public void setVALUE(String VALUE) {
this.VALUE = VALUE;
}
public String getVALUE() {
return this.VALUE;
}
}
The main class with a dummy main method:
import java.util.ArrayList;
import java.util.List;
public class Main {
public static void main(String[] args) {
List<Email> emailList = new ArrayList<>();
emailList.add(new Email("Primary", "pri#mail7.io"));
emailList.add(new Email("Primary", "amimulahsan7#gmail.com"));
//And list goes on......
PostAccountCreateAPI postAccountCreateAPI = new PostAccountCreateAPI("arpita", "garg",
"P#$$w0rd", emailList);
}
}

The first parameter to the constructor is List<Email>, but you are currently passing a String as the first argument to the constructor. Create a list of Email objects and then invoke the PostAccountCreateAPI constructor.

JPARepository searching queries returning null

I am having trouble understanding why my userRepository is returning null even when there is a record like it in my table. I tried doing it with my demo codes and it works but when I try doing it with user Authentication it does not work.
Security Services
#Path("/securityservice")
public class SecurityServices {
private UserRepository userRepo;
// http://localhost:8990/login/securityservice/security
#GET
#Path("security")
#Produces(MediaType.APPLICATION_JSON)
public Response getOrderById(#QueryParam("orderId") int orderID,
#HeaderParam("Authorization") String authString) throws JSONException {
JSONObject json = new JSONObject();
if (isUserAuthenticated(authString)) {
json.put("INFO", "Authorized User!");
return Response.status(200)
.entity(json.toString())
.type(MediaType.APPLICATION_JSON)
.build();
} else {
json.put("ERROR", "Unauthorized User!");
return Response.status(403)
.entity(json.toString())
.type(MediaType.APPLICATION_JSON)
.build();
}
}
private boolean isUserAuthenticated(String authString) {
//authString = Basic 3hfjdksiwoeriounf
String[] authParts = authString.split("\\s+");
//authParts[0] = Basic
//authParts[1] = 3hfjdksiwoeriounf
String authInfo = authParts[1];
byte[] bytes = Base64.getDecoder().decode(authInfo);
String decodedAuth = new String(bytes);
// decodedAuth = dj:1234
String[] credentials = decodedAuth.split(":");
//credentials[0]=dj
//credentials[1]=1234
System.out.println("HELLO"+credentials[0]);
System.out.println("HELLO"+credentials[1]);
User user = userRepo.findByUsername(credentials[0]); //this line returns null
if (user != null) {
return true;
} else {
return false;
}
}

Issues adding data to Firebase Realtime database

So I'm having a strange issue with Firebase, and I can't seem to find any info on it. I'm attempting to add a user object to the database. When I check Firebase, it's created an object with the correct username, but it doesn't add any of the attributes that are Strings, and the 2 double attributes are zero. I've turned off user authentication for now, until I get this working. Here's the relevant code:
public class User {
public String email;
public String password;
public String firstName;
public String lastName;
public String dob;
public double height;
public double weight;
public String gender;
public User()
{
}
public User(String email, String password, String firstName, String lastName, String DoB, double height, double weight, String gender) {
}
public String getEmail()
{
return email;
}
public String getPassword()
{
return password;
}
public String getFirstName()
{
return firstName;
}
public String getLastName()
{
return lastName;
}
public String getdob()
{
return dob;
}
public double getHeight()
{
return height;
}
public double getWeight()
{
return weight;
}
public String getGender()
{
return gender;
}
public void setEmail(String email)
{
this.email = email;
}
public void setPassword(String password)
{
this.password = password;
}
public void setFirstName(String firstName)
{
this.firstName = firstName;
}
public void setLastName(String lastName)
{
this.lastName = lastName;
}
public void setdob(String dob)
{
this.dob = dob;
}
public void setHeight(double height)
{
this.height = height;
}
public void setWeight(double weight)
{
this.weight = weight;
}
public void setGender(String gender)
{
this.gender = gender;
}
}
final FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference usersRef = database.getReference();
...
private void registerUser() {
usersRef.child("testuser").setValue(new User("test#test.com", "password", "First", "Last", "2000/01/01", 172, 75, "Male"));
After that completes, if I check Firebase, it shows "users", with an object called "testuser", but the testuser's only attributes are height and weight, both with value 0. If I change height and weight to Strings instead of doubles, nothing at all is added to the database. As far as I can tell, everything is pretty much identical to the Firebase docs, so I'm pretty well stumped. Anyone seen anything like this?

First, delete the static keyword from your User class declaration. Should only be:
public class User {}
Add the no-argument constructor needed for Firebase.
public User() {}
Add also the getters and setters for all of your fields.
This how your model class should look like:
public class User {
private String email;
private String password;
private String firstName;
private String lastName;
private String dob;
private double height;
private double weight;
private String gender;
public User() {}
public User(String email, String password, String firstName, String lastName, String dob, double height, double weight, String gender) {
this.email = email;
this.password = password;
this.firstName = firstName;
this.lastName = lastName;
this.dob = dob;
this.height = height;
this.weight = weight;
this.gender = gender;
}
public String getEmail() {return email;}
public String getPassword() {return password;}
public String getFirstName() {return firstName;}
public String getLastName() {return lastName;}
public String getDob() {return dob;}
public double getHeight() {return height;}
public double getWeight() {return weight;}
public String getGender() {return gender;}
}

Java Spring password encoding fail

I don't know why my UserEntity.java fail to encode the password when I test it in debug mode. The password appear without MD5 encoded. Else is when I click on org.springframework.security.authentication it's say:
this element has no attached Javadoc and the Javadoc could not be found in the attached source
I have springframework-core in Maven dependencies which contain the both classes of Md5PasswordEncoder.java and PasswordEncoder.java.
If this two needs a bean definition how do I create it?
package com.example.j2eeapp.domain;
import java.io.Serializable;
import org.springframework.security.authentication.encoding.Md5PasswordEncoder;
import org.springframework.security.authentication.encoding.PasswordEncoder;
/**
* Entity to hold application user data - first name, last name, etc.
*/
public class UserEntity implements Serializable {
private static final long serialVersionUID = 9014169812363387062L;
private String firstName;
private String lastName;
private String userName;
private String password;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
PasswordEncoder crypto = new Md5PasswordEncoder();
this.password = crypto.encodePassword(password, null);
}
}

Logging In With JSP Hibernate

I have a problem with Hibernate to make login process. All codes are perfectly correct in terms of syntax. NetBeans tell me that my code have no problem. However, when I run the web, and I test the login process, it doesn't reacting and the address is stucked on the doLogin.
All classes have been mapped correctly.
This is my problem: when I try to retrieve data, my code is stucked on a line.
on doLogin servlet (I use the template provided by NetBeans and just filling in my code on the try. Here's in brief:
Connect con = new Connect(); //my code is stucked on this line.
//I've done testing where's the cause of the stuck, and this line is the cause.
List logger = con.getLogin(username, password);
and to make it clear:
Connect.java
public class Connect {
Session sesi;
public Connect() {
sesi = HibernateUtil.getSessionFactory().openSession();
}
public List getLogin(String username, String password){
return sesi.createQuery("from MsUser WHERE username = '"+username+"' and password = '"+password+"'").list();
}
}
and since that query is HQL, here is the MsUser class:
public class MsUser {
public MsUser() {
}
private int userID;
private String username;
private String firstname;
private String lastname;
private String email;
private String password;
private String gender;
private String address;
private String phone;
private String photo;
public MsUser(int userID, String username, String firstname, String lastname, String email, String password, String gender, String address, String phone, String photo) {
this.userID = userID;
this.username = username;
this.firstname = firstname;
this.lastname = lastname;
this.email = email;
this.password = password;
this.gender = gender;
this.address = address;
this.phone = phone;
this.photo = photo;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public String getPhoto() {
return photo;
}
public void setPhoto(String photo) {
this.photo = photo;
}
public int getUserID() {
return userID;
}
public void setUserID(int userID) {
this.userID = userID;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
}
please help. But I suspect on Connect's constructor as the main cause. Anybody can suggest or fix or tell me what causing me this.
appendix:
HibernateUtil.java
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package Controller;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.SessionFactory;
/**
* Hibernate Utility class with a convenient method to get Session Factory
* object.
*
* #author Ginanjar
*/
public class HibernateUtil {
private static final SessionFactory sessionFactory;
static {
try {
// Create the SessionFactory from standard (hibernate.cfg.xml)
// config file.
sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();
} catch (Throwable ex) {
// Log the exception.
System.err.println("Initial SessionFactory creation failed." + ex);
throw new ExceptionInInitializerError(ex);
}
}
public static SessionFactory getSessionFactory() {
return sessionFactory;
}
}

You can try following code in your hibernateUtil.java file:
SessionFactory factory = new Configuration().configure().buildSessionFactory();
session = factory.openSession();
String query = "select reg.username,reg.password from MsUser as reg where reg.username='" + username + "' and reg.password='" + password + "'";
Query DBquery = session.createQuery(query);
for (Iterator it = DBquery.iterate(); it.hasNext();) { it.next();
count++;
}
System.out.println("Total rows: " + count);
if (count == 1) {
return true;
} else {
return false;
}
}
