使用put方法更新jpa中的实体

Question

如何使用put方法更新jpa中的实体？

我正在使用以下JSON进行更新：

{
    "acceptedGender":"both",
    "price":123123.00,
    "type":"apartment",
    "vacantNum":13,
    "hadID":4
}

我使用下面的put方法进行更新是否正确？

有人可以帮助我

这是我的代码：

@javax.ejb.Stateless
@Path("com.balay.entity.hatypes")
public class HaTypesFacadeREST extends AbstractFacade<HaTypes> {

    @PersistenceContext(unitName = "BalayRSPU")
    private EntityManager em;

    public HaTypesFacadeREST() {
        super(HaTypes.class);
    }

    **@POST
    @Override
    @Consumes({MediaType.APPLICATION_JSON})
    public void create(HaTypes entity) {
        em = Persistence.createEntityManagerFactory("BalayRSPU").createEntityManager();
        try{
          em.getTransaction().begin();
          em.persist(entity);
          em.getTransaction().commit();
       }finally{
          em.close();
       }
    }**

@PUT
@Path("{id}")
@Consumes({MediaType.APPLICATION_JSON})
public void edit(@PathParam("id") Integer id, HaTypes entity) {
            em = 
          Persistence.createEntityManagerFactory("BalayRSPU").
          createEntityManager();
      try{
        em.getTransaction().begin();
         Admin update = em.getReference(Hatypes.class, id);
      update = entity;
      em.persist(update);
        em.getTransaction().commit();
    }finally{
        em.close();
    }
}

@DELETE
@Path("{id}")
public void remove(@PathParam("id") Integer id) {
    super.remove(super.find(id));
}

@GET
@Path("{id}")
@Produces({MediaType.APPLICATION_JSON})

    return super.find(id);
}

    return String.valueOf(super.count());
}

@Override

    em = 
Persistence.createEntityManagerFactory("BalayRSPU").createEntityManager();
    return em;
}

}
