使用spring和hibernate开发了一个Web应用程序。这是一个非常庞大的应用程序，我也必须从控制器外部获得一些服务。为此，我使用xmlclasspathcontext同时获取bean。
目前我正在使用threadlocal和opensession。到目前为止我没有问题，除了在更新某些东西时读取旧数据。我知道这是因为threadlocal保持当前会话。
我想学的是，İF我删除threadlocal并使用öpensession和close会话这是一个好方法吗？ 因为我不能同时使用控制器和getbeans的getcurrentsession。 İam没有在xmXML get bean端找到错误的会话。有没有办法在两边得到getcurrentsession？或者我是否必须使用开放和关闭会话方法？什么İF我不关闭每个opwnsession？

这是我收到请求的Controller类
@Controller
public class UserController {
@Autowired
private UserService userService;
@Autowired
private LoginHistoryService loginHistoryService;
@RequestMapping(value = "/loginAttempt", method = RequestMethod.POST)
public @ResponseBody
String loginAttempt(HttpServletRequest request, HttpServletResponse response) throws UnsupportedEncodingException {
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
String userName = request.getParameter("userName");
String password = request.getParameter("password");
User user = userService.getByUserNameAndPassword(userName, password);
if (user != null) {
if (user.isActive()) {
LoginHistory loginHistory = new LoginHistory();
loginHistory.setCreated(new Date());
loginHistory.setIpAddress(request.getRemoteAddr());
loginHistory.setSessionId(request.getSession().getId());
loginHistory.setAccountVerified(Boolean.TRUE);
loginHistory.setUser(user);
boolean loginHistoryCreated = loginHistoryService.create(loginHistory);
if (loginHistoryCreated) {
return "ok";
} else {
//Error
return "err";
}
} else {
return "err";
}
}
return "ok";
}
}
这是服务层
@Service("loginHistoryService")
@Transactional（propagation = Propagation.REQUIRED，readOnly = true，isolation = Isolation.SERIALIZABLE） public class LoginHistoryServiceImpl extends GenericServiceImpl实现了LoginHistoryService {
@Autowired
private LoginHistoryDAO loginHistoryDAO;
public LoginHistoryDAO getLoginHistoryDAO() {
return loginHistoryDAO;
}
public void setLoginHistoryDAO(LoginHistoryDAO loginHistoryDAO) {
this.loginHistoryDAO = loginHistoryDAO;
setGenericDAO(loginHistoryDAO);
}
@Transactional(propagation = Propagation.REQUIRED, readOnly = false)
@Override
public boolean create(LoginHistory obj) {
return loginHistoryDAO.create(obj);
}
这部分是DAO层
@Repository("loginHistoryDAO")
公共类LoginHistoryDAOImpl扩展GenericDAOImpl实现LoginHistoryDAO {
@Autowired
private SessionDAO sessionDAO;
@Override
public boolean create(LoginHistory obj) {
try {
//beginTransaction();
save(obj);
if (obj.isAccountVerified()) {
Session s = new Session();
s.setActive(Boolean.TRUE);
s.setIpAddress(obj.getIpAddress());
s.setCreated(new Date());
s.setSessionId(obj.getSessionId());
s.setUser(obj.getUser());
sessionDAO.save(s);
}
//commitTransaction();
} catch (Exception e) {
handleException(e);
return false;
}
return true;
}
}
最后一部分是通用部分
@SuppressWarnings("unchecked")
@Repository 公共抽象类GenericDAOImpl实现GenericDAO {
@Autowired
private SessionFactory sessionFactory;
private final Class<T> persistentClass;
public GenericDAOImpl() {
this.persistentClass = (Class<T>) ((ParameterizedType) getClass().getGenericSuperclass()).getActualTypeArguments()[0];
}
public Class<T> getPersistentClass() {
return persistentClass;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public Session getCurrentSession() throws HibernateException {
return sessionFactory.getCurrentSession();
}
@Override
public Transaction beginTransaction() {
return getCurrentSession().beginTransaction();
}
@Override
public void commitTransaction() {
getCurrentSession().getTransaction().commit();
我正在尝试将openSession（）替换为getCurrentSession（） 我需要控制beginTransaction（）和tx.commit（）。因为我有多个实体可以同时保存或更新。所以，我需要在事务中包含这些内容，确保所有内容都完成或者所有内容都没有完成。
当我使用getCurrentSession（）时，我收到此错误;

我想取消ThreadLocal并使用getCurrentSession。 这里有什么问题还是你有其他目的。实际上我可以对所有dao中的任何方法使用opensession（）和closeSession。如果我这样做是为了减慢我的系统？ 我在等待解决方案谢谢
