Spring请求映射具有不同的参数和一个相同的参数

Question

我有弹簧代码，请求如下：

@RequestMapping(method = RequestMethod.GET, value = {
        EnterpriseLiterals.ROOT_URL_SIMPLE + "storeDepartments/search.json",
        EnterpriseLiterals.ROOT_URL_SIMPLE + "storeDepartments/search" },params = { "!dealerStoreId" })
public Map<String, List<? extends AbstractDepartment>> getDepartments(
            @RequestParam(value = "enterpriseId", required = true) String enterpriseId,@RequestParam(value = "responseFields", required = false) String responseFields)

另一个请求为：

@RequestMapping(method = RequestMethod.GET, value = {
        EnterpriseLiterals.ROOT_URL_SIMPLE + "storeDepartments/search",
        EnterpriseLiterals.ROOT_URL_SIMPLE + "storeDepartments/search.json" },params = {"!enterpriseId"})
@ResponseBody
public Map<String, List<AbstractDepartment>> getDepartmentListBasedOnStoreAndDeptType(@RequestParam(value = "dealerStoreId", required = true) String dealerStoreId,@RequestParam(value = "responseFields", required = false, defaultValue = "summary") String responseFields)

但是，由于我在两个请求中都有responseFields，当我使用responseFields调用上述API并且“ResponseFields不存在”时，我收到错误。 请帮助解决这个问题的解决方案。
