其实解决这个问题就是要保证整个数据插入过程中字符编码要一致。要有三个方面注意的，

第一个是msyl数据库，就是保证mysql的数据库以及表都要保证编码是一致的比如都是UTF-8，

第二个是，eclipse这边也要保证项目，工作空间和java文件的编码格式也是UTF-8，

第三个是，就是配置文件里面jdbc的url的（jdbc:mysql://localhost:3306/mybatis?characterEncoding=utf8）后面也要设置编码characterEncoding=utf8（这个问题以前没遇到，这次出现乱码最后才发现是他的缘故）

对于大家都说要改什么my.ini的配置文件，这个我没有去修改，用的是Mysql的默认文本,如下图所示
