Ambiguous mapping found. Cannot map 'homeController' bean method

springmvc 在做项目的时候出现Ambiguous mapping found. Cannot map 'homeController.Create' bean method

的错误信息，调查发现在controller中url映射出现重复，@RequestMapping(value = "home12.action")

RequestMapping注解中的value值出现重复，全文搜索查看home12.action是否在其他controller中也引用到了。
