java - POST 不在数据库中插入数据

Question

我被困在一个网络服务项目上。我有一个包含 5 个方法(4 个 GET 方法和 1 个 POST 方法)的资源类。每个 GET 方法都有效(也就是说，可以从数据库中提取数据)。但是我的 POST 方法不起作用(这是数据推送到数据库的地方)。问题发生在 Hibernate 提交上。

我使用的是 jdk 7、tomcat 6.0.41、jersey 2.x。

我的 POST 方法的代码是:

@POST
@Path("/")
@Produces(MediaType.APPLICATION_JSON)
public Response postRequisicao(@FormParam("uuid") String uuid, @FormParam("geometria") String geometria, @FormParam("itens") String itensId) {
    try {
        LocalChecklist localChecklist = new LocalChecklist(uuid, new Date(), (Point) wktToGeometry(geometria));
        LocalItemChecklistDAO.save(localChecklist, itensId);
    } catch(Exception e) {
        return Response.serverError().build();
    }
    return Response.ok().build();
}

我的 LocalChecklistDAO.save() 方法的代码是:

public static void save(LocalChecklist localChecklist, String itensId) {
    Session session = HibernateUtil.getSessionFactory().openSession();
    session.beginTransaction();
    session.save(localChecklist);
    for(ItemChecklist itemChecklist: ItemChecklist.getListFromIds(itensId)) {
        LocalItemChecklist item = new LocalItemChecklist(localChecklist, itemChecklist);
        session.save(item);
    }
    session.getTransaction().commit();
    session.close();
}

session.getTransaction().commit(); 行中发送的异常是:

我认为值得一提的是:在提交之前，我可以看到对象可以从数据库序列中获取其ID，即在save()之前，其ID为空(正如预期的那样)，并且在 save() 之后(以及在 commit() 之前)对象获得了它应该获得的确切 ID(如预期的那样，来自序列)。

有人能看到什么吗？

我认为你必须分开你的交易，并 promise 你收到的税。

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 
Session session = sessionFactory.openSession(); 
Transaction tx = session.beginTransaction();
session.save(item);
tx.commit();
