返回状态信息实体类省略get和set

    private String stauts;
    private String msg;

控制器

    @RequestMapping(value = "register", method = RequestMethod.POST,
    consumes = "application/json",produces = "application/json")
    @ResponseBody
    public ResponseResult register(@RequestBody RegisterInfo registerInfo) {

        System.out.println(registerInfo.getName());
        ResponseResult result = null;
        if (service.register(registerInfo)){
            result = new  ResponseResult("sucess","注册成功");
        }else {
            result = new  ResponseResult("error","注册失败");
        };
        return result;
    }

js代码中$.fn.serializeObject序列化对象，location.href实现跳转，

<script>
    function register() {
        var jsonInfo = $('#myform').serializeObject();
        var jsonString = JSON.stringify(jsonInfo);
        console.log(jsonString);
        $.ajax({
            type:'POST',
            data:jsonString,
            url:"/register?t="+new Date().getTime(),
            contentType:"application/json",
            success:function (data,type) {
                alert(data.msg);
                location.href="/"
            },
            error:function () {
                alert(data.msg);
            }
        })
    }
    $.fn.serializeObject = function() {
        var o = {};
        var a = this.serializeArray();
        $.each(a, function() {
            if(o[this.name]) {
                if(!o[this.name].push) {
                    o[this.name] = [o[this.name]];
                }
                o[this.name].push(this.value || '');
            } else {
                o[this.name] = this.value || '';
            }
        });
        return o;
    };
</script>
