Register your own custom editor.
public class SqlDateEditor extends PropertyEditorSupport {
private DateFormat dateFormat;
public SqlDateEditor (final DateFormat dateFormat)
{
this.dateFormat = dateFormat;
}
#Override
public void setAsText(String text) {
try {
setValue(new java.sql.Date(this.dateformat.parse(text).getTime())
} catch (ParseException e) {
throw new IllegalArgumentException("Could not parse date: " + e.getMessage());
}
}
#Override
public String getAsText() {
java.sql.Date value = (java.sql.Date) getValue();
return (value != null ? this.dateFormat.format(value) : "");
}
}
At your controller:
#InitBinder
public void initBinder(final WebDataBinder binder) {
binder.registerCustomEditor(java.sql.Date.class, new SqlDateEditor(new SimpleDateFormat("dd/MM/yyyy")));
}

Your request has to match the #RequestBody object for spring to map the keys appropriately
Try this request -

"address":{
"cityname":"california",
"streetname":"ring road",
"Housename":"Housename"
}
}

Please make sure you give input as per your Model.

}
}

For delete based on id, since your primary key is not int id you have to write the below custom code in your interface extending JpaRepository.
And in your rest controller you have to invoke it like repository.deleteById(id);
#Repository
public interface UserRepository extends JpaRepository<User,String> {
#Modifying
#Transactional
#Query(value="delete from User u where u.id= ?1")
void deleteById(int id);
}
Similarly you may have to write code for your update statement as well (for PUT case).
Hope this helps.

Do you have any ideas how to resolve this problem?
Thank you for all your help :)

Change your HQL from this:
from employees order by last_name
To this:
from Employee e order by e.lastName
In HQL you should use namings the same as your mapped class.

If you are using HQL, then java Entity names should be used instead of real table names:
#Repository
public class EmployeeDAOImpl implements EmployeeDAO {
#Override
public List<Employee> getEmployees() {
Session currentSession = sessionFactory.getCurrentSession();
return currentSession.createQuery("from Employee order by last_name").getResultList();
}
}

I think that there is an error in EmployeeDAOImpl.java. Change "employees" to "Employee" and "last_name" to "lastName" (names should be the same as in the mapped class(Employee.java))
Just change:
#Override
public List<Employee> getEmployees() {
Session currentSession=sessionFactory.getCurrentSession();
List<Employee> employeeList=
currentSession.createQuery("from employees order by
last_name").getResultList();
return employeeList;
}
to:
#Override
public List<Employee> getEmployees() {
Session currentSession=sessionFactory.getCurrentSession();
List<Employee> employeeList=
currentSession.createQuery("from Employee order by
lastName").getResultList();
return employeeList;
}
and tell us if it worked :)

JPA with Spring MVC doesn't insert into database using persist

I am using spring 4 and hibernate 4 to create some web services and when I try to retrieve data from the database. It work fine but the problem is when I try to insert data.
When I lunch the project as a java application every thing work fine. The problem is only when I lunch it on the server and I am using tomcat.
This is my entity:

and this is the controller

result.put("content", metier.listAllSpecialite());
return result;
}
}
package com.pfe.ecole.controller;

}
#RequestMapping(value="/teachers/{page}/{items}",method=RequestMethod.GET)

}
private Page getAll(int page, int items){
return new Page(page,metier.count(),metier.listAll(page, items));
}
}
this is the test that works as java application
public static void main(String[] args) {
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext("root-context.xml");
ISpecialite m = (ISpecialite) context.getBean("specialiteImpl");
Specialite s= new Specialite("Web Dev");
m.add(s);
}
This is the error I am getting
javax.persistence.TransactionRequiredException: No EntityManager with actual transaction available for current thread - cannot reliably process 'persist' call

adding this annotation to service solved the problem #EnableTransactionManagement
