## 一、概述 有時候同一個實體，在不同業務中，需要將字段改為另外一個名字顯示； ## 二、解決方案 在controller中，加上配置； ``` @RayDynamicRenameFieldsInListEntityGroup({ // @RayDynamicRenameFieldsInListEntity(renameFieldPairs = "showUsedFlow:usedFlow;showLeftFlow:leftFlow;showFlowQuota:flowQuota")// }) ``` ## 三、完整方案 可以支持分頁、普通列表以及單個實體的字段改名，支持多重組合等； 分頁： ``` @RayDynamicRenameFieldsInPageEntityGroup @RayDynamicRenameFieldsInPageEntity ``` 普通列表： ``` @RayDynamicRenameFieldsInListEntityGroup @RayDynamicRenameFieldsInListEntity ``` 單個實體： ``` @RayDynamicRenameFieldsInSingleEntityGroup @RayDynamicRenameFieldsInSingleEntity ``` 其他一些注意事項可以類比參考：[項目實戰/后端開發/返回結果處理/返回字段過濾](%E8%BF%94%E5%9B%9E%E5%AD%97%E6%AE%B5%E8%BF%87%E6%BB%A4.md) ## 四、組合使用實例 ``` @PostMapping(RayOauthServerConstants.rayOauthApiUrlPrefix + apiRequestSimpleUrl) @RayDynamicFilterFieldsInListEntityGroup({ // @RayDynamicFilterFieldsInListEntity(listObject = "listobject", excludeFields = "relaxRate,executeRate,usedFlow,leftFlow,flowQuota"), // @RayDynamicFilterFieldsInListEntity(listObject = "historyList", excludeFields = "relaxRate,executeRate,usedFlow,leftFlow,flowQuota")// }) @RayDynamicRenameFieldsInListEntityGroup({ // @RayDynamicRenameFieldsInListEntity(listObject = "listobject", renameFieldPairs = "showUsedFlow:usedFlow;showLeftFlow:leftFlow;showFlowQuota:flowQuota"), // @RayDynamicRenameFieldsInListEntity(listObject = "historyList", renameFieldPairs = "showUsedFlow:usedFlow;showLeftFlow:leftFlow;showFlowQuota:flowQuota")// }) public ResponseEntity<ResponseObject> view(@RequestHeader(required = false) String rayOauthServerAppId, @RequestHeader(required = false) String rayOauthServerTimeStamp, @RequestHeader(required = false) String rayOauthServerSignature, @RequestParam(required = false) String userCode) throws Exception { return ResponseEntity.ok(commonQueryFlow.response(getOauthClient(), getOauthApi(), getOauthApiRequest(), getOauthRequestParameters())); } ```
