1. 分析情况

   上述情况

Caused by: java.lang.IllegalStateException: Ambiguous mapping found. Cannot map ‘userController’ bean method
非法状态异常?发现模棱两可的映射,不能映射userController中的bean方法.
Cannot map ‘userController’ bean method
public ServerResponse UserController.logout(HttpSession)
to {[/user//login.do],methods=[POST],params=[],headers=[],consumes=[],produces=[],custom=[]}: There is already ‘userController’ bean method
public ServerResponse UserController.login(String,String,HttpSession) mapped.
不能映射userController的bean方法,logout(HttpSession),因为这里已经有了login(String,String,HttpSession)方法,
也就是说这两个方法冲突了,查看源代码发现
@RequestMapping(value=”login.do”,method = RequestMapping.POST)两个方法重复了

1. 解决问题

   把logout方法的@RequestMapping改成logout.do

2. 验证问题
