标题：Hibernate4 No Session found for current thread与createQuery is not valid without active transaction异常
描述：
在项目程序运行时遇到了Hibernate4 No Session found for current thread异常，
百度了一下
在hibernate的配置文件中加入了thread
配置并且处理业务逻辑的类上也加入了注解如下
package com.xiaonei.baseService;
import java.util.List;
import javax.annotation.Resource;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.transaction.annotation.Transactional;
@Transactional
public class BaseServiceImpl implements BaseService {
@Resource
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory() {
return sessionFactory;
}
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
/**
- @author sunlong
- @param hql：传入的hql，可以带参数？
-
@param args: 问号对应的参数数组
*/
@Override
public List<?> getResult(String hql, Object[] args) {Session session = sessionFactory.getCurrentSession(); System.out.println("执行到创建Session"); Query query = session.createQuery(hql); System.out.println("执行到Query"); if(args!= null && args.length > 0){ for(int i = 0;i<args.length;i++){ query.setParameter(i, args[i]); } } return query.list();}
但是当我再次运行程序时，出现了createQuery is not valid without active transaction异常
然后我就接着百度，解决方法是把hibernate配置文件中的thread
配置删除或者把值thread改成org.springframework.orm.hibernate3.SpringSessionContext
再次运行却又出现了org.springframework.orm.hibernate3.SpringSessionContext异常整了好久都没搞明白，这是为什么呀？
Spring 的配置文件
1.applicationContext.xml
<context:property-placeholder location="classpath:db.properties"/>
<!-- 配置 C3P0 数据源 -->

<!-- 配置 Spring 的声明式事务 -->
<!-- 1. 配置 hibernate 的事务管理器 -->

<!-- 2. 配置事务属性 -->

<!-- 3. 配置事务切入点, 再把事务属性和事务切入点关联起来 -->

<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
