参数有问题,不能解析成json对象
ajax提交添加下面两行代码
contentType:'application/json;charset=utf-8'
			data:JSON.stringify(数据)
var allData = {
          name:"张三",
          age:20
         };
$.ajax({
            type: "POST",
            url: "xxxx",
            contentType:'application/json;charset=utf-8',
            data:JSON.stringify(allData),
            success: function (data) {
                alert(data);
            }
        });
注意:
后端如果用springMVC的@RequestBody注解的话,则只能Json对象的字符串,不能接收Json对象,用 JSON.stringify(data)的方式将对象变成字符串,同时ajax请求也要指定dataType: "json",contentType:"application/json" ,这样就能用@RequestBody注解绑定对象或者List集合.
