Context initialization failed

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping#0': Initialization of bean failed; nested exception is java.lang.IllegalStateException: Ambiguous mapping found. Cannot map 'teacherController' bean method 

Caused by: java.lang.IllegalStateException: Ambiguous mapping found. Cannot map 'teacherController' bean method 

在修改了数据库表和表关联后，相应的后台也要跟着改变，但是一直会报这个错误，说bean注入失败，找了好久才发现是命名重复了，就是@RequestMapping(value = { "###" })

和另一个控制器的命名相同发生冲突，特地写下来，警示复制有风险。
