SpringMVC舊的寫法

在SpringMVC項目中寞蚌，通常是用controller層來接受前端傳過來的數(shù)據(jù)椭蹄，但是我們目前都是用JSONObject來接收值，需要多做一步解析jsonObject的動作 例子如下：

$.ajax({
    url:"<%=contextPath%>/entry/saveOrUpdateEntry",
    type:'POST',
    data:nui.encode(json),
    cache:false,
    contentType:'application/json',
    success:function(text){
    }
});

@ResponseBody
@RequestMapping(value = "/saveOrUpdateEntry")
public Map<String, Object> saveOrUpdateEntry(@RequestBody JSONObject jsonObject , HttpSession session) {
           ·····

優(yōu)化寫法

一個參數(shù)對象情況

json = {"empCode":"80489179"}

$.ajax({
    url:"<%=contextPath%>/entry/saveOrUpdateEntry",
    type:'POST',
    data:nui.encode(json),
    cache:false,
    contentType:'application/json',
    success:function(text){
        
    }
});

@ResponseBody
@RequestMapping(value = "/saveOrUpdateEntry")
public Map<String, Object> saveOrUpdateEntry(String empCode , HttpSession session) {
           ·····

一個bean的情況

json = {"empCode":"80489179","empName":"李明”净赴，“age":"15"}

$.ajax({
    url:"<%=contextPath%>/entry/saveOrUpdateEntry",
    type:'POST',
    data:nui.encode(json),
    cache:false,
    contentType:'application/json',
    success:function(text){
        
    }
});

@ResponseBody
@RequestMapping(value = "/saveOrUpdateEntry")
public Map<String, Object> saveOrUpdateEntry(@RequestBody User user, HttpSession session) {
     
 class User{
     private String empCode;
     private String empName;
     private Integer age;
     ···
 }              

一個Bean+一個list情況

json = {"empCode":"80489179","empName":"李明","age":"15","list":[{"id":"1","name":"小啊"},{"id":"2","name":"小明"}]}

$.ajax({
    url:"<%=contextPath%>/entry/saveOrUpdateEntry",
    type:'POST',
    data:nui.encode(json),
    cache:false,
    contentType:'application/json',
    success:function(text){
        
    }
});

@ResponseBody
@RequestMapping(value = "/saveOrUpdateEntry")
public Map<String, Object> saveOrUpdateEntry(@RequestBody EmpVo empvo, HttpSession session) {
     
 class EmpVo{
     private String empCode;
     private String empName;
     private Integer age;
     private List<Dict> list;
     绳矩。。玖翅。
     翼馆。割以。。
     应媚。严沥。
 }      
 class Dict{
     private Integer id;
     private String name;
 }

多個Bean+一個list情況

json = {"user":{"empCode":"80489179","empName":"李明”，"age":"15"},"list":[{"id":"1","name":"小啊"},{"id":"2","name":"小明"}],"like":{"hobby":"我的愛好","spcial":"沒有系好"}}

$.ajax({
    url:"<%=contextPath%>/entry/saveOrUpdateEntry",
    type:'POST',
    data:nui.encode(json),
    cache:false,
    contentType:'application/json',
    success:function(text){
        
    }
});

@ResponseBody
@RequestMapping(value = "/saveOrUpdateEntry")
public Map<String, Object> saveOrUpdateEntry(@RequestBody Vo vo, HttpSession session) {
     
 class Vo{
     private User user;
     private Like like;
     private List<Dict> list;
     ···
 }      
 class Dict{
     private Integer id;
     private String name;
 }
 class Like{
     private String hobby;
     private String spcial;
 }
 class User{
     private String empCode;
     private String empName;
     private Integer age;
     ···
 }
