mybatis 学习记录

在mybatis 中无法插入记录

显示信息如下：

运行插入语句始终不能成功，但是一直没有注意这个语句

530  DEBUG [main] org.apache.ibatis.transaction.jdbc.JdbcTransaction     - Rolling back JDBC Connection [com.mysql.jdbc.JDBC4Connection@5f8172]

想一想在insert里面也没有用到事务啊，不知道是什么原因？

在执行语句出添加事务提交 就可以插入成功 ，

        SqlSession sqlsesstion = sc.openSession();

        sqlsesstion.insert("insertperson", person);
         sqlsesstion.commit();  //还不知道是什么原因要提交事务才可以插入数据成功，但是每一次似乎都对数据库产生了影响
        sqlsesstion.close();

有一点乱 ！！！
