flex+spring+ hibernate OpenSessionInViewFilter延时配置问题

   在联级查询中如果不配置OpenSessionInViewFilter则flex端将无法显示数据，但配置了OpenSessionInViewFilter

将

<filter>
	  <filter-name>hibernateFilter</filter-name>
	  <filter-class>org.tianwei.common.MyOpenSessionInViewFilter</filter-class>
	  <init-param>
	            <param-name>singleSession</param-name>
	            <param-value>true</param-value>
	  </init-param>
	</filter>
	
	<filter-mapping>
	  <filter-name>hibernateFilter</filter-name>
	  <url-pattern>/*</url-pattern>
	</filter-mapping>

 

中的 <param-value>true</param-value>设置成true，则不能调用hibernate的更操作功能，折磨了几天的。好在最后在http://xuliangyong.iteye.com/blog/144818 找到解决的方法，就是重写OpenSessionInViewFilter类

上面的配置是重写之后的配置，希望对大家有用。同时非常感谢xly_971223，

public class MyOpenSessionInViewFilter extends OpenSessionInViewFilter {
	 protected Session getSession(SessionFactory sessionFactory) 
	 	throws DataAccessResourceFailureException {    
	        Session session = SessionFactoryUtils.getSession(sessionFactory, true);    
	        this.setFlushMode(FlushMode.AUTO); 
	        /*FlushMode flushMode = getFlushMode();    
	        if (flushMode != null) {    
	            session.setFlushMode(flushMode);    
	        }    */ 
	        return session;    
	    } 
	    
	    protected void closeSession(Session session, SessionFactory sessionFactory){ 
	        session.flush(); 
	        super.closeSession(session, sessionFactory); 
	    }
}

我的么用Spring也出现

org.hibernate.SessionException: Session is closed
org.hibernate.jdbc.JDBCContext.connection(JDBCContext.java:126)
org.hibernate.transaction.JDBCTransaction.rollbackAndResetAutoCommit(JDBCTransaction.java:183)
org.hibernate.transaction.JDBCTransaction.rollback(JDBCTransaction.java:162)

问题怎么办了……
