出现Error creating bean with name 'org.springframework.web.servlet.mvc.method....................模糊映射

 在启动Maven项目中出现

创建名称为“org.springframework.web.servlet.mvc.method.annotation”的bean时出错。RequestMappingHandlerMapping': init方法调用失败;嵌套异常是java.lang。IllegalStateException:模糊映射。无法映射'portalItemCatController'方法...

严重: StandardWrapper.Throwable

解决 :如图所示 红色箭头所指;在Controller层下的方法中@RequestMapper URL路径一样 这样框架就不知道到你要访问哪一个

XXXXXXController.java  要确保@RequestMapper URL 一致性
