配置好mysql应该有的配置文件后，点击idea中右边的Database
依次点击
?将Driver调成如下的MySQLfor 5.1，填写好用户名与密码和数据库然后点击 Test Connection
?如下情况就是可以了，不行的话可以查一下其他攻略
?完成后点击OK，此时mysql就已经链接上了
自动生成类?
然后对student表单机右键，点击mybatis generator
?配置好对应的选项
?
?
然后点击ok
?
?此时类已经为我们自动生成了，由于controllerc层是与前端交互的接口，需要我们自行进行配置
总结
mybatis-plus为我们定义了很多的方法可以直接调用他的方法对单表进行增删改查。
