Question

我在postgres中有一个非常简单的数据库，我已经使用了hibernate来连接＆＃34; connect＆＃34;它。一切正常，我用hibernate测试数据库，到目前为止没有问题。

这是我的DAO

@Repository("clientsBasicDao")
@Transactional
public class ClientsBasicDaoImpl implements ClientsBasicDao {


private Log log = LogFactory.getLog(ClientsBasicDaoImpl.class);
private SessionFactory sessionFactory;  
private Session session;


public SessionFactory getSessionFactory() {
    return sessionFactory;
}


@Resource(name="sessionFactory")
public void setSessionFactory(SessionFactory sessionFactory) {
    this.sessionFactory = sessionFactory;
    session = sessionFactory.openSession();
}

@SuppressWarnings("unchecked")
@Transactional(readOnly=true)
public List<ClientsBasic> findAllClients() throws HibernateException{
    return session.createQuery("from ClientsBasic").list();
}

public ClientsBasic findClientById(int id) throws HibernateException {
    return (ClientsBasic) session.
            getNamedQuery("ClientsBasic.findById").setParameter("id", id).uniqueResult();
}

public ClientsBasic findClientByEmail(String email) throws HibernateException{
    return (ClientsBasic) session.
            getNamedQuery("ClientsBasic.findByEmail").setParameter("email", email).uniqueResult();
}

@SuppressWarnings("unchecked")
public List<ClientsBasic> findDirectClients() throws HibernateException{
    return session.getNamedQuery("ClientsBasic.findDirectClients").list();
}

@SuppressWarnings("unchecked")
public List<ClientsBasic> findIndirectClients() throws HibernateException{
    return session.getNamedQuery("ClientsBasic.findIndirectClients").list();
}

public ClientsBasic save(ClientsBasic client) throws HibernateException {
    Transaction tx = null;
    tx = session.beginTransaction();
    session.saveOrUpdate(client);
    tx.commit();
    log.info("Client saved with id: " + client.getClientId());

    return client;
}
public void delete(ClientsBasic client) throws HibernateException  {
    Transaction tx = null;

    tx = session.beginTransaction();
    Set<Resources> res = client.getClientResources();
    if(res.size() > 0){ //there are client access resources for this client
        Iterator<Resources> it = res.iterator();
        while(it.hasNext()){
            Resources resource = it.next();
            resource.getClientsBasics().remove(client);
        }
    }
    session.delete(client);
    tx.commit();
    log.info("Client deleted with id: " + client.getClientId());    

}

}

现在，我正在尝试学习宁静的Web服务，所以在一些教程之后我尝试了自己的实现。它起作用，除非我尝试使用连接到数据库的方法。

@RestController
public class GreetingController {

private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();


//http://localhost:8080/TestProject/greeting  
//          or
//http://localhost:8080/TestProject/greeting?name=stackoverflow
@RequestMapping("/greeting")
public @ResponseBody String greeting(
        @RequestParam(value="name", required=false, defaultValue="World") String name) {
    return new Greeting(counter.incrementAndGet(),
                        String.format(template, name)).toString();
}


//http://localhost:8080/TestProject/testing
@RequestMapping("/testing")
public @ResponseBody String home(){
    return "Welcome, the server is now up and running!";
}


//http://localhost:8080/TestProject/client?id=1
@RequestMapping("/client") 
public @ResponseBody String client(     //FAILS HERE
        @RequestParam(value="id", required=true) String id){

    ClientServiceBackend cb = new ClientServiceBackend();
    return cb.findClient(Integer.parseInt(id));
}

}

这是错误

像我说的那样，我正在努力学习休息，这是我春天的第二周，所以这对我来说都是新的，但我希望这可以工作，因为数据库工作正常！

注意：我正在Tomcat v7上部署它

有人可以请一下吗？

谢谢： - ）

修改我将hibernate jar添加到tomcat类路径，现在错误是 匹配的通配符是严格的，但是找不到元素＆t; tx：annotation-driven＆＃39;

的声明。
