1、异常信息

在运行Springboot项目时，出现了如下异常信息：模糊映射。无法映射的xxx方法，异常信息如下：

Caused by: java.lang.IllegalStateException: Ambiguous mapping. Cannot map 'tacticsInfoController' method 
public com.soft.framework.core.response.PageResult<?> com.soft.back.operation.controller.openplatform.TacticsInfoController.getOutdevModelList(java.lang.Integer)
to {GET /tactics/getOutdevFactoryList}: There is already 'tacticsInfoController' bean method
public com.soft.framework.core.response.PageResult<?> com.soft.back.operation.controller.openplatform.TacticsInfoController.getOutdevFactoryList(java.lang.String) mapped.

2、异常原因

控制层同一请求映射到两个方法，即controller层的方法指定了两个相同的路径，也就是说同一个项目中有两个@RequestMapping("/xxx"）完全相同，就会报此错误信息

3、解决办法

两个相同的@RequestMapping("/xxxx/xxxx")改为不同的请求路径，查看报错地方，找出同一请求映射到两个方法的请求路径，修改后即可！

完结！
