有点懵，test标签“=”后面的username、address等等指的是我们输入的值，还是数据库表里面的值？或者说它们指的是谁？
用这个怎么多表查询
老师，这个是版本问题，需要改那部分
为包设置别名，测试大小写都可以运行成功
这样怎么查不出来
运行不起来
model 这个参数不要可以吗？下面没用到啊
这里一定要用代理对象吗？另一个老师是直接绑定的，两种都可以吗?
老师，为什么把is/session/还有代理对象想变成全局对象需要先设置成空值啊
aspectj-autoproxy>标签什么时候要加expose-proxy="true"配置选项？
aspectj-autoproxy>标签什么时候要加
expose-proxy="true"
配置选项？
