31           * @param isAutoCommit 
32           *         true 表示创建的SqlSession对象在执行完SQL之后会自动提交事务
33           *         false 表示创建的SqlSession对象在执行完SQL之后不会自动提交事务，这时就需要我们手动调用sqlSession.commit()提交事务
34           * @return SqlSession
35           */
36         public static SqlSession getSqlSession(boolean isAutoCommit) {
37              return getSqlSessionFactory().openSession(isAutoCommit);

有了这个辅助类，获取sqlsession来进行数据的增删改查就不容自己再一遍一遍的写了
