spring3与hibernate4整合session问题

[color=red][b]问题描述:[/b][/color]
整合spring3与hibernate4时,发生错误:[u]nested exception is org.hibernate.HibernateException: No Session found for current thread[/u]

之后查找资料,添加[u]:thread[/u]属性,报错:org.hibernate.HibernateException: createQuery is not valid without active transaction,
查找资料说,删除上面我添加的那个属性,我被陷入死循环了。
[color=red][b]代码如下[/b][/color]

[b]DAO[/b]
[code="java"]
package com.test;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

public class BaseDao {
@Autowired
private SessionFactory sessionFactory;

public Session getCurrentSession() {
    return sessionFactory.getCurrentSession();

}

[/code]

[code="java"]
package com.test.dao.impl;

import java.util.List;

import org.hibernate.Query;
import org.springframework.stereotype.Repository;

import com.test.BaseDao;
import com.test.dao.IUserDao;

@Repository
public class UserDaoImpl extends BaseDao implements IUserDao{

各层次的ioc都OK的,问题出在哪里,或者解答下原因也可以,我自己查找资料,谢谢了。

小东 过滤器的形式可以,但服务器整体性能不是下降了吗,还有更好的解决方式吗

是否是这里配置错误?

com..entity



改成这样试试 加载这个包下的所有实体类




com..entity*



没有获取到受事务管理的session

hibernate4获取session有一个限制,就是session必须在事务级别上才能获取到
你可以在你的service加上事务配置就没有问题了
例如
[code="java"]



/aop:config

<tx:advice id="txAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="save*" propagation="REQUIRED" isolation="DEFAULT" />
        <tx:method name="load*" propagation="REQUIRED" isolation="DEFAULT" read-only="true" />
        <tx:method name="get*" propagation="REQUIRED" isolation="DEFAULT" read-only="true" />
        <tx:method name="find*" propagation="REQUIRED" isolation="DEFAULT" read-only="true" />
        <tx:method name="list*" propagation="REQUIRED" isolation="DEFAULT" read-only="true" />
        <tx:method name="*" propagation="REQUIRED" isolation="DEFAULT" />
    </tx:attributes>
</tx:advice>[/code]

小东 针对事物我做了传播式的配置,不可以

方法有点问题
public Session getSession() {
Session session = null;
try {
session = sessionFactory.getCurrentSession();
} catch (HibernateException he) {
session = sessionFactory.openSession();
}
return session;
}
