springboot通过ajax上传json

Springboot通过Ajax上传json对象

1.使用@RequestParam

@PostMapping(value = "/search")
@ResponseBody
private String search(@RequestParam("mobile") String mobile) {
    System.out.println(mobile);
    JSONObject.parse(mobile);
    //  System.out.println(jsonObj);
    JSONObject result = new JSONObject();
    result.put("msg", "ok");
    return result.toJSONString();
}

 

$.ajax({
    type: "POST",
    url: "/user/search",
    dataType: 'json',
    data: { "mobile": mobile },
    success: function(data) {
        console.log(data);
    },
    error: function(data) {
        console.log(data);
    }
})

java端接收到的值直接是mobile的值，打印出来直接是一个手机号

System.out.println(jsonString); 的输出结果是：18810888888

 

2.使用@RequestBody

@PostMapping(value = "/search")
@ResponseBody
private String search(@RequestBody String jsonString) { //@RequestParam("mobile") String mobile
    System.out.println(jsonString);
    //  System.out.println(jsonObj);
    JSONObject result = new JSONObject();
    result.put("msg", "ok");
    return result.toJSONString();
}

$.ajax({
    type: "POST",
    url: "/user/search",
    dataType: 'json',
    data: { "mobile": mobile },
    success: function(data) {
        console.log(data);
    },
    error: function(data) {
        console.log(data);
    }
})

System.out.println(jsonString);的输出结果是 mobile=18810888888
