Unable to install breakpoint in .....Absent Line Number Information

最近搭了一个SSM项目，在登录页面.do上打了个断点，第二天启动时一直报这个错，进不了断点。

基本解决方式如下：
1.项目右键->Properties->Java Compiler->add line number attributes to generated in class files(used by the debugger)->勾选

2.Window->Preferences->java->Installed JRES->配置你安装的JRE

3.1,2解决基本就搞定了，百度如是说，我的不是这个问题

我打了两个断点，后来发现只有LoginService这个类打断点会报错，去掉就好了，具体为啥还不道
后来发现我手动停止server时会报错

原因是SqlSessionTemplate是一个代理类，为每次请求创建线程安全的sqlSession,与spring继承，由spring管理自动关闭，
修改配置文件
重新编译-部署-载关闭tomcat就不会报错了。
