（一）ajax返回格式
1，默认返回字符串，页面也会转成字符串（text）
参考：
http://www.cnblogs.com/bujianchenxi/p/6060799.html
2返回页面
$.ajax({
type:'post',
url:'后台路径',
dataType:'html',
success:function(result){
//console.info(result);
$("#test").html(result);
}
});
注意：dataType:'html'为html类型，后台实现，如下：
@RequestMapping(value = "test")
public String test(Model model) {
model.addAttribute("test","test");
return "modules/test/test";
}
return一个页面，例如上面的对应的视图为test.jsp

3，ajax json 前台接收解析
var dataJsonObject = JSON.parse(data);
if (dataJsonObject.returnCode == 1 ) {
（二）ajax传输json格式：
ajax json 前台打包传输
遇到“”里面套用“”需要转义
1,使用转义符，此时不需要JSON.stringify()后传递过去（整个不用引号引起）
var jsonsWxInFo="{\"result\":{" +
"\"baseInfo\":{\"liveAddress\":\"\",\"tenementCity\":\"\",\"homePhone\":\"\",\"tenementAddress\":\"\",\"qqAccount\":\"\",\"hasTenement\":\"\",\"liveCity\":\"\",\"monthSalary\":\"\",\"educationLevel\":\"\",\"marriage\":\"\",\"id\":\"\",\"weixinAccount\":\"\",\"tenementType\":\"\",\"email\":\"\",\"hasCar\":\"\",\"liveStarttime\":\"\"}," +

function saveDetailWX(){
alert(6);
$.ajax({
url: '${ctx}/itm/weixin/saveWXOrderInfo.action',
data: {
jsonsWxInFo: jsonsWxInFo // 图片数据流
},
dataType: 'json',
type: 'post',
success: function(data) {
var dataJsonObject = JSON.parse(data);
if (dataJsonObject.returnCode == 'A0001' ) {
}else{
alert('图片上传失败!');
}
},
error: function(xhr,type,errorThrown) {
alert('网络异常，请稍后再试！');
}
});
}
2，不使用转义符，此时用JSON.stringify()将数据传递过去
var jsonsWxInFo={"result":{
"baseInfo":{"liveAddress":"","tenementCity":"","homePhone":"","tenementAddress":"","qqAccount":"","hasTenement":"","liveCity":"","monthSalary":"","educationLevel":"","marriage":"","id":"","weixinAccount":"","tenementType":"","email":"","hasCar":"","liveStarttime":""},
"contactInfo":{"immediateFamilyIdcard":"","postAddress":"","spousePhone":"","contactPerson":"","contactPersonPhone":"","getProductWay":"","immediateFamilyPhone":"","contactPersonRelation":"","spouse":"","nonImmediateFamilyName":"","nonImmediateFamilyRelation":"","immediateFamilyName":"","spouseIdcard":"","nonImmediateFamilyPhone":"","immediateFamilyRelation":"","isFamilyKNow":"","marryDate":""},
"policyInfo":{"actualYear":"","policyName":"","inputUserid":"","shouldYear":"","inputDate":"","paymentType":"","lifeInsuranceYearSum":"","inputOrgId":"","monthAmt":"","useDate":"","policyCount":"","policyType":"","customerId":"","insuranceName":"","policyIndex":""},
"additionalInfo":{"otherIdentityPicUrl":"","otherPicUrl":"","loanPicUrls":"","juzhuzhengPicUrls":"","creditCardPicUrls":"","hukoubenPicUrls":"","gongzuozhengPicUrls":"","identityFrontPicUrl":"bluckname=test&imgName=MTExLnBuZzE1MDc3MDkzNTkxNzI=.png","identityBackPicUrl":"","marriageCertificatePicUrls":"","zichanLetterPicUrls":"","id":"4","shouruLetterPicUrls":""},
"additionalInfoRemarks":{"dealUserid":"","createTime":"","dealUsername":"","remark":"","id":""},
"applyInfo":{"loanTerm":"","purpose":"","applyAmount":""},
"careerInfo":{"jobName":"","reserveFundsRadix":"","salaryDate":"","companyCity":"","companyType":"","hasSocialSecurity":"","industry":"","jobLevel":"","industryForth":"","salaryWithoutTax":"","employeeType":"","companyPhone":"","industrySecond":"","companyAddress":"","industryThird":"","company":"","department":"","socialSecurityRadix":"","employeeAmount":""},
"creditInfo":{"bankPicUrls":"","peopleBankPicUrls":"","reserveFundsPicUrls":"","id":""}},
"orderNo":"A001","state":"","isEiditAble":"1"};
function saveDetailWX(){
alert(6);
$.ajax({
url: '${ctx}/itm/weixin/saveWXOrderInfo.action',
data: {
jsonsWxInFo: JSON.stringify(jsonsWxInFo) // 图片数据流
},errorThrown) {
alert('网络异常，请稍后再试！');
}
});
}
后台json结构数据和实体转化
public String saveWXOrderInfo(){
QueryOrderDetailReqqp=(QueryOrderDetailReq)JSONObject.toBean(JSONObject.fromObject(jsonsWxInFo),QueryOrderDetailReq.class);
//baseService.save();
BaseResp br = new BaseResp();
br.setReturnCode(WeixinErrorMsg.SUCCESS.getCode());
br.setReturnMsg(WeixinErrorMsg.SUCCESS.getText());
result= JSONObject.fromObject(br).toString();
return SUCCESS;
}
