SpringMvc Json接收和返回的处理
一、第一种处理方式
1、Controller 控制层
@RequestMapping(value = "/getXkzbhAndEntname",produces = "text/json;charset=UTF-8") @ResponseBody public String getXkzbhAndEntname(HttpServletRequest request, HttpServletResponse response, String xkzbh,String entname) throws Exception{ JSONObject jObject = new JSONObject(); PageData pd=new PageData(); try { pd = qyjcxxService.getEntityByXkzbhAndEntname(xkzbh,entname); if (pd!=null) { //json格式 jObject.put("flag", "true"); jObject.put("msg", ""); jObject.put("fddbr", pd.getString("fddbrfzr"));//法定代表人 fddbrfzr jObject.put("fzr", pd.getString("lxr"));//fzr 负责人 lxr jObject.put("lxdh", pd.getString("lxr_sjhm"));//lxdh 联系电话 lxr_sjhm jObject.put("xxdz", pd.getString("scjy_dz"));//xxdz 市场地址 scjy_dz jObject.put("qyjj", pd.getString("scfw"));//qyjj 简介 scfw jObject.put("ssjgjname", pd.getString("rcjdgljg_mc"));// 监管局名称 rcjdgljg_mc jObject.put("ssjgj", pd.getString("rcjdgljg_dm"));//ssjgj 监管局代码 rcjdgljg_dm } else { //json空格式 jObject.put("flag", "flase"); jObject.put("msg", "企业库不含有该企业信息，无法补全！"); jObject.put("fddbr", "");//法定代表人 fddbrfzr jObject.put("fzr", "");//fzr 负责人 lxr jObject.put("lxdh", "");//lxdh 联系电话 lxr_sjhm jObject.put("xxdz", "");//xxdz 市场地址 scjy_dz jObject.put("qyjj", "");//qyjj 简介 scfw jObject.put("ssjgjname", "");// 监管局名称 rcjdgljg_mc jObject.put("ssjgj", "");//ssjgj 监管局代码 rcjdgljg_dm } } catch (Exception e) { e.printStackTrace(); jObject.put("flag", "flase"); jObject.put("msg", "获取企业库信息失败"); jObject.put("fddbr", "");//法定代表人 fddbrfzr jObject.put("fzr", "");//fzr 负责人 lxr jObject.put("lxdh", "");//lxdh 联系电话 lxr_sjhm jObject.put("xxdz", "");//xxdz 市场地址 scjy_dz jObject.put("qyjj", "");//qyjj 简介 scfw jObject.put("ssjgjname", "");// 监管局名称 rcjdgljg_mc jObject.put("ssjgj", "");//ssjgj 监管局代码 rcjdgljg_dm } return jObject.toString(); }
2、js处理
//获取企业库是否有数据 $("#btnGetData").click(function () { var ztbh = $("#txtZtbh").val(); var ztmc = $("#txtZtmc").val(); //取mySql的企业库数据 $.ajax({ url: "<%=basePath %>login/getXkzbhAndEntname.do", type: "POST", async: false, data: { xkzbh : ztbh, entname : ztmc }, dataType: "text", contentType : "application/x-www-form-urlencoded; charset=utf-8", success: function (data) { var dataObj = JSON.parse(data);//转成json格式 //alert(data); //alert(dataObj); if(dataObj.flag) { alert(dataObj.msg); if(dataObj.fddbr!=null) { $("#txtfddbr").val(dataObj.fddbr); } } else { alert(dataObj.msg); } }, error: function (data) { alert('许可证号验证异常！'); } }); });
返回值json格式：
二、第二种处理方式
判断记录是否存在的json处理
1、controller
@RequestMapping(value = "/existsZtmcUpdate") @ResponseBody public String existsZtmcUpdate(HttpServletRequest request, HttpServletResponse response, String ztmc,String ztid)throws Exception { Boolean existsResult = false; try { existsResult = 验证代码; } catch (Exception e) { e.printStackTrace(); } if (existsResult) { return "1"; } else { return "0"; } }
2、js
//验证市场机构名称 $("#txtZtbh").blur(function(){ return verifyZtbh(); }); function verifyZtbh(){ var ztbh = $("#txtZtbh").val(); var flag = false; if(ztbh == ''){ $("#msgZtbh").text('许可证号不能为空！'); return false; } $.ajax({ url: "<%=basePath %>login/existsZtbh.do", type: "POST", async: false, data: { ztbh : ztbh }, dataType: "text", contentType : "application/x-www-form-urlencoded; charset=utf-8", success: function (data) { var json = eval(data); if(json == 1){ $("#msgZtbh").text('许可证号已被注册！'); }else{ $("#msgZtbh").text(''); flag = true; } }, error: function (data) { $("#msgZtbh").text('许可证号验证异常！'); } }); if(flag){ $("#msgZtbh").text(''); return true; }else{ return false; } }
三、第三种处理方式，数组方式批量上报数据
1、controller
@RequestMapping(value = "/receivedata", method = RequestMethod.POST) @ResponseBody public ReturnJsonInfo receivedata(HttpServletRequest request,HttpServletResponse response,@RequestBody Fasttestinfo fasttestinfo) { ReturnJsonInfo returninfo=new ReturnJsonInfo(); try { String username=fasttestinfo.getUsername(); String password=fasttestinfo.getPassword(); String areacode=""; String areaname=""; String ssjgjcode=""; String ssjgjname=""; Boolean ischeck=false; //验证username和密码if(ischeck) { //查看有几组数据 //System.out.println(fasttestinfo.getItems().length); //组织数据进行数据写入 //System.out.println(fasttestinfo.getItems()[0].getSamplenum() + " " + fasttestinfo.getUsername()); if(fasttestinfo.getItems().length>0) { //将数据处理到List中 List<FasttestinfoInfo> fasttestinfoList = new ArrayList<FasttestinfoInfo>(); int errorItem=0; // 包装对象 for (int i = 0; i < fasttestinfo.getItems().length; i++) { FasttestinfoInfo fasttestinfoInfo = new FasttestinfoInfo(); String id = UuidUtil.get32UUID(); fasttestinfoInfo.setId(id); fasttestinfoInfo.setUserName(username); fasttestinfoInfo.setQueryId(fasttestinfo.getItems()[i].getQuery_id()); fasttestinfoInfo.setGallery(fasttestinfo.getItems()[i].getGallery()); fasttestinfoInfo.setSamplenum(fasttestinfo.getItems()[i].getSamplenum()); fasttestinfoInfo.setSamplename(fasttestinfo.getItems()[i].getSamplename()); fasttestinfoInfo.setCov(fasttestinfo.getItems()[i].getCov()); fasttestinfoInfo.setSymbol(fasttestinfo.getItems()[i].getSymbol()); fasttestinfoInfo.setCovUnit(fasttestinfo.getItems()[i].getCov_unit()); fasttestinfoInfo.setStandNum(fasttestinfo.getItems()[i].getStand_num()); fasttestinfoInfo.setCreateTime(DateUtil.getCurrentTime()); fasttestinfoInfo.setPosttype(1); fasttestinfoList.add(fasttestinfoInfo); } // if(errorItem>0) // { // returninfo.setFlag("false"); // returninfo.setMsg("json中items第"+errorItem+"项不是时间格式"); // return returninfo; // } //插入数据库 if(fasttestinfoService.addBatch(fasttestinfoList)) { returninfo.setFlag("true"); returninfo.setMsg("数据接收成功！"); } else { returninfo.setFlag("false"); returninfo.setMsg("上报数据接收失败"); } } else { returninfo.setFlag("false"); returninfo.setMsg("json中items数组为空"); } } else { //企业不存在，或企业用户名和密码有误 returninfo.setFlag("false"); returninfo.setMsg("企业不存在或企业用户名和密码有误！"); } } catch (Exception e) { returninfo.setFlag("false"); returninfo.setMsg(e.toString()); } return returninfo; }
ReturnJsonInfo类
/** * 返回json格式 实体类 * 2017-11-19 22:04:45 */ public class ReturnJsonInfo{ private String flag; private String msg; /** * 重写toString方法 */ @Override public String toString() { return ToStringBuilder.reflectionToString(this); } public String getFlag() { return flag; } public void setFlag(String flag) { this.flag = flag; } public void setMsg(String msg){ this.msg = msg; } public String getMsg(){ return msg; } }
2、js处理
$.ajax({ url:'http://localhost:8080/interface/receivedata.do', type:'POST', dataType:'json', contentType:'application/json;charset=UTF-8', data:JSON.stringify({ username:'aaa', password:'123456', items:[{ query_id:'检测记录id2', gallery:'通道id断模块的依据2', samplenum:'样品编号2', samplename:'样品名称2', cov:'判定值sy2', symbol:'判定符号2', cov_unit:'检测单位2', stand_num:'判定标准号2', prosecutedunits:'被检单位2' } ] }), success : function(result) { alert(JSON.stringify(result)); }, error:function(XMLHttpRequest, textStatus, errorThrown) { alert(XMLHttpRequest); alert(textStatus); alert(errorThrown); } });
