Java--- Ambiguous mapping. Cannot map "***Controller" been method解决办法

打开网页报错：

Ambiguous mapping. Cannot map 'handController' method 

public com.smallchill.core.toolbox.ajax.AjaxResult com.smallchill.smtlamp.controller.HandController.AC2off(java.lang.String)

to {[/hand/AC1off]}: There is already 'handController' bean method

public com.smallchill.core.toolbox.ajax.AjaxResult com.smallchill.smtlamp.controller.HandController.AC1off(java.lang.String) mapped.

 

解决办法：

@RequestMapping()中的url重复了，修改为不同的url即可；
