I have this particular xml file(in that exact format) that I am trying to parse with JAXB
Because the properties are all on a single line it doesn't see them and returns all fields as null in my main function. How can I parse the xml correctly in it's format?
<?xml version="1.0" encoding="UTF-8"?>
<employees>
<employee firstName="Asya" id="2" lastname="Olshansky"/>
</employees>
This is the code for employee
#XmlRootElement(name = "employee")
#XmlAccessorType (XmlAccessType.FIELD)
public class Employee implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String firstName;
private String lastName;
public Employee() {
super();
}
//Setters and Getters
#Override
public String toString() {
return "Employee [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + "]";
}
}
Employees code:
#XmlRootElement(name = "employees")
#XmlAccessorType(XmlAccessType.FIELD)
public class Employees {
#XmlElement(name = "employee")
List<Employee> employees = null;
public List<Employee> getEmployees() {
return employees;
}
public void setEmployees(List<Employee> list) {
this.employees = list;
}
}
This is the Main execution:
public static void main(String[] args)
{
String fileName = "employee.xml";
jaxbXmlFileToObject(fileName);
}
private static void jaxbXmlFileToObject(String fileName) {
File xmlFile = new File(fileName);
JAXBContext jaxbContext;
try
{
jaxbContext = JAXBContext.newInstance(Employees.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Employees employees = (Employees) jaxbUnmarshaller.unmarshal(xmlFile);
for(Employee e: employees.getEmployees() )
System.out.println(e);
}
catch (JAXBException e)
{
e.printStackTrace();
}
}
Try:
Employee.java:
public class Employee implements Serializable {
private static final long serialVersionUID = 1L;
private Integer id;
private String firstName;
private String lastName;
public Employee() {
super();
}
public Employee(Integer id, String firstName, String lastName) {
super();
this.id = id;
this.firstName = firstName;
this.lastName = lastName;
}
#XmlAttribute(name="id")
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
#XmlAttribute(name="firstName")
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
#XmlAttribute(name="lastname")
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
#Override
public String toString() {
return "Employee [id=" + id + ", firstName=" + firstName + ", lastName=" + lastName + "]";
}
}
Employees.java:
#XmlRootElement(name="employees")
public class Employees {
List<Employee> employees;
public Employees() {}
public Employees(List<Employee> employees) {
super();
this.employees = employees;
}
#XmlElement(name="employee")
public List<Employee> getEmployees() {
return employees;
}
public void setEmployees(List<Employee> list) {
this.employees = list;
}
}
Output:
Note:
No changes in Main.
Updated Employee and Employees class.
Added #XmlAttribute in Employee to map attribute names and getter/setters.
Added #XmlElement in Employees to map each employee element inside the employees tag and constructor also.

Below is the service class.
#GET

public Response getStudentJson(){

} catch (SQLException e) {

}
return Response.ok(studentsList).build();
}
Kindly help me to achieve the above mentioned output.
Thanks in Advance.
To get the desired output, you will have to create one single root object containing a List<Student> student and return it:
Root.java
#XmlRootElement(name="root")
public class Root implements Serializable {
#XmlList
private List<Student> student = new ArrayList<Student>();
// getter and setter
}
Service.java
#GET
#Path("/student.srv")
#Produces("application/json")
public Response getStudentJson(){
DAOLayer daoLayer=new DAOLayer();
List<Student> studentsList=null;
try {
studentsList=daoLayer.getStudents();
} catch (SQLException e) {
e.printStackTrace();
}
Root root = new Root();
root.setStudent(studentsList),
return Response.ok(root).build();
}
data_user = "{"id":1,"lastName":"lastName","name":"name","school":{"id":1}}"
public class School {
private int id;
private String name;
}
public class User {
private int id;
private String lastName;
private String name;
private School school;
}
How to deserialize Json data_user to java object User?
I tried with Gson :
Gson gson = new Gson();
User user = gson.fromJson(data_user, User.class)
But I have an error with this code because the Json contains a school which hasn't the school's name.
How Can I serialize the Json to java Object?
School.java
public class School {
private int id;
private String name;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
#Override
public String toString() {
return "School [id=" + id + ", name=" + name + "]";
}
}
User.java
public class User {
private int id;
private String lastName;
private String name;
private School school;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public School getSchool() {
return school;
}
public void setSchool(School school) {
this.school = school;
}
#Override
public String toString() {
return "User [id=" + id + ", lastName=" + lastName + ", name=" + name
+ ", school=" + school + "]";
}
}
Main.java
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.testgson.beans.User;
public class Main {
private static Gson gson;
static {
gson = new GsonBuilder().create();
}
public static void main(String[] args) {
String j = "{\"id\":1,\"lastName\":\"lastName\",\"name\":\"ignacio\",\"school\":{\"id\":1}}";
User u = gson.fromJson(j, User.class);
System.out.println(u);
}
}
Result
User [id=1, lastName=lastName, name=ignacio, school=School [id=1, name=null]]
Try with the Jackson Library. With Gson with should have not any problem, I tried with the code of #Saurabh and it work well
I'm trying to use JPA for the first time in a project. Most of my entities are working fine, but I am having trouble with one which is part of a Joined Inheritance Strategy.The entities are also being serialised by Jackson so they also have Json annotations.
The parent "User" class:
(Edit: added "Type" field)
#JsonTypeInfo(use=JsonTypeInfo.Id.NAME, include= JsonTypeInfo.As.WRAPPER_OBJECT)
#JsonTypeName("user")
#JsonSubTypes({
#JsonSubTypes.Type(name="customer", value=Customer.class),
#JsonSubTypes.Type(name="employee", value=Employee.class)})
#Entity(name = "User")
#Table(name="user")
#Inheritance(strategy = InheritanceType.JOINED)
#DiscriminatorColumn(name="type",discriminatorType = DiscriminatorType.INTEGER)
#NamedQuery(name="User.all",query = "select u from User u")

Everything to do with "employee" works file, I can use the named query Employee.all to find all the employees in the database.
However, If I try to retrieve any customers I get errors. If I try to run the named query Customer.all I get:
java.lang.IllegalArgumentException: NamedQuery of name: Customer.all not found.
If I try to use EntityManager's find() method to find a particular customer I get:
javax.servlet.ServletException: Exception [EclipseLink-43] (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: Missing class for indicator field value [2] of type [class java.lang.Integer].
Descriptor: RelationalDescriptor(com.technicalpioneers.cod.user.User --> [DatabaseTable(user)])
I don't understand why the Customer entity is not being found by JPA. I've checked the user table and the "type" column is there with correct numbers, and #DescriminatorValue is set correctly. It's almost like the annotations are being ignored?
Have done many clean rebuilds and redeploys too. Any help would be very much appreciated!
I found this eventually. https://bugs.eclipse.org/bugs/show_bug.cgi?id=429992
It turns out EclipseLink will silently ignore entities with lambda expressions! Very annoying for it to not be at least mentioned in logs!
Thanks to everyone who took the time!

As stated the persons are saved in the person table but not the relationship in the person_friend table. Why?
Perhaps it has something to do with transaction boundaries. Try to make your test method #Transactional.
