springMVC——解析不同格式的JSON字符串

格式一 

            function userinfo(username, password){
                this.username = username;
                this.password = password;
            }
            
            function sendAjax1(){
                var userinfoRef = new userinfo("今天很热","123");
                var jsonStringRef = JSON.stringify(userinfoRef);
                $.ajax({
                    type: "POST",
                    data: jsonStringRef,
                    url: "getJSON1.spring?t=" + new Date().getTime(),
                    contentType: "application/json",               
                });
            }

	@RequestMapping("getJSON1")
	public void createJSON1(@RequestBody Userinfo userinfo) {
		System.out.println("username value=" + userinfo.getUsername());
		System.out.println("password value=" + userinfo.getPassword());
	}

格式二

            function sendAjax2(){
            	var myArray = new Array();
            	myArray[0] = "星期一";
            	myArray[1] = "星期二";
            	myArray[2] = "星期三";
            	myArray[3] = "星期四";
            	myArray[4] = "星期五";
            	
            	var jsonString = JSON.stringify(myArray);
            	$.ajax({
            		type:"POST",
            		data:jsonString,
            		url:"getJSON2.spring?t="+new Date().getTime(),
            		contentType:"application/json"
            	});
            }

	@RequestMapping("getJSON2")
	public void createJSON2(@RequestBody ArrayList<String> list){
		for(int i=0;i<list.size();i++){
			System.out.println(list.get(i));
		}
	}

格式三

            function userinfo(username, password){
                this.username = username;
                this.password = password;
            }
            
            function sendAjax3(){
            	var myArray = new Array();
            	myArray[0] = new userinfo("星期一","看电影");
            	myArray[1] = new userinfo("星期二","逛街");
            	myArray[2] = new userinfo("星期三","打球");
            	myArray[3] = new userinfo("星期四","跑步");
				myArray[4] = new userinfo("星期五","休息");   
				
				var jsonString = JSON.stringify(myArray);
				$.ajax({
					type:"POST",
					data:jsonString,
					url:"getJSON3.spring?t="+new Date().getTime(),
					contentType:"application/json"
				});         	
            }

	@RequestMapping("getJSON3")
	public void createJSON3(@RequestBody ArrayList<Map> list){
		for(int i=0;i<list.size();i++){
			Map map = list.get(i);
			System.out.println(map.get("username")+"  "+map.get("password"));
		}
	}

            function sendAjax4(){
            	var jsonObject = {
            		"username":"张三丰",
            		"kongfu":[{"taiji":"太极"},{"taiji":"太极拳"}],
            		"school":{"small":"小和尚","old":"掌门"}
