我有以下代码:

    @Test
    public void springTest() throws SQLException{
        //Connect to the DB.
        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setDriverClassName("org.h2.Driver");
        dataSource.setUrl("jdbc:h2:/data/h2/testa");
        dataSource.setUsername("");
        dataSource.setPassword("");
        JdbcTemplate jt=new JdbcTemplate(dataSource);
        jt.execute("SELECT 1");
        jt.execute("SELECT 1");
    }

我希望两个execute()行重用相同的连接.但是,日志输出说:
