一、應用場景
當前端發出Ajax請求,後端需要返回Map結果集
二、程式碼
1、ResultFactory.java
package com.XXXX.tv.vrs.service.util; import java.util.HashMap; import java.util.Map; public class ResultFactory { public static Map<String,Object> makeOkResult(Object data){ Map<String,Object> res = new HashMap<String,Object>(); res.put("status", StatusCode.OK); res.put("msg", StatusCode.OK_MSG); res.put("data", data); return res; } public static Map<String,Object> makeErrorResult(){ Map<String,Object> res = new HashMap<String,Object>(); res.put("status", StatusCode.SERVER_ERROR); res.put("msg", "Error"); res.put("data", null); return res; } }
2、controller
@RequestMapping("/uppdateSensitiveWord.do") @ResponseBody public Map<String,Object> updateSensitiveWord(String sensitiveInput,String sensitiveWordBeUpdate){ Map<String,Object> map = new HashMap<String,Object>(); try { Long rs=sensitiveWordService.updateSensitiveWord(sensitiveWordBeUpdate,sensitiveInput); map = ResultFactory.makeOkResult(rs); }catch(Exception e) { e.printStackTrace(); map = ResultFactory.makeErrorResult(); } return map; }
3、JS
function updateSensitiveWord() { var sensitiveInput=$.trim($("#sensitive").val()); var sensitiveWordBeUpdate=$.trim($("#sensitiveWordUpdate").val()); //alert(sensitiveWordBeUpdate+"--->"+sensitiveInput); $.post("uppdateSensitiveWord.do", {sensitiveInput: sensitiveInput, sensitiveWordBeUpdate:sensitiveWordBeUpdate}, function(rs){ if(rs.status==200 &&rs.data!=0){ alert("修改成功"); window.location.reload(); }else if(rs.status==200 &&rs.data==0){ alert("資料庫中已存在敏感詞"+sensitiveInput+",修改失敗"); }else{ alert("修改失敗"); } }); }
