本文探讨了在Spring框架中因控制器方法URL映射不清晰导致的异常问题。通过分析具体的代码实例，指出了@RequestMapping注解下相似路径配置引发的问题，并提出了修改建议，确保每个方法的映射路径明确无误。

Ambiguous handler methods mapped for HTTP path 'http://localhost:18080/business/DictionaryController/2': {public java.lang.String com.ztesoft.zsmart.pot.controller.business.dictionary.DictionaryController.deleteDict(java.lang.String) throws com.ztesoft.zsmart.core.exception.BaseAppException, public java.lang.String com.ztesoft.zsmart.pot.controller.business.dictionary.DictionaryController.deleteItem(java.lang.String,java.lang.String) throws com.ztesoft.zsmart.core.exception.BaseAppException}]

异常的大概意思是：模糊映射；

查看action文件，发现没有出现问题

/*
* 以下是关于页面中对于父级记录以及子级记录进行删除的操作
* 1、父级记录的删除按钮跳转
* 2、子级记录的删除按钮跳转
*/
delDict: function(dictCode, success) {
   debugger;
           fish.remove("DictionaryController/" + dictCode, success);
       },
delItem: function(dictCode,itemCode,success) {
   debugger;
           fish.remove("DictionaryController/" + dictCode,itemCode,success);
           debugger;
       },

然后查看controller文件，发现问题所在

   //库表结构左侧删除记录
   @RequestMapping(value = "{dictCode}", method = RequestMethod.DELETE)
public String deleteDict(@PathVariable String dictCode) throws BaseAppException {
if (service.deleteDict(dictCode) == 1) {
return com.ztesoft.zsmart.pot.controller.web.utils.Const.SUCCESS;
}
else {
return com.ztesoft.zsmart.pot.controller.web.utils.Const.FAILED;
}
}
   //子级删除操作
   @RequestMapping(value = "{dictCode,itemCode}", method = RequestMethod.DELETE)
public String deleteItem(@PathVariable String dictCode,@PathVariable String itemCode) throws BaseAppException {
if (service.deleteItem(dictCode,itemCode) == 1) {
return com.ztesoft.zsmart.pot.controller.web.utils.Const.SUCCESS;
}
else {
return com.ztesoft.zsmart.pot.controller.web.utils.Const.FAILED;
}
}
