Java Postgresql和GlassFish-启用自动提交时无法提交

我有

postgresql9.4

和

glassfish4.1

。此外，我在EJB中使用MyBatis。现在我尝试从表中选择，我得到的结果如下：

我甚至尝试了以下代码：

SqlSession session = ConnectionFactory.getSession().openSession(false);//AUTOCOMMIT
        List list=null;
        try{
            session.getConnection().setAutoCommit(false);
            TempMapper mapper = (TempMapper)session.getMapper(TempMapper.class);
            list=mapper.readAll();
        }  
        catch (SQLException ex) {
            Logger.getLogger(TempBean.class.getName()).log(Level.SEVERE, null, ex);
        }        finally {
            session.close();
        }

然而，结果是一样的。当我使用gf+mysql+mybatis时，我更改了relaxautocommit，但对于postgresql驱动程序，没有这样的属性。如何解决此问题？

解决方案：在glassfish web控制台中打开postgresql池，并在事务部分设置启用非事务性连接。

在glassfish管理控制台中。
