JAVA后台接收并解析/反序列化前端传过来的JSON字符串

前端将JSON字符串传后台:

var json = {
	"name": "hibiki",
	"age": 24,
}; 
//或者
var json = {};
json["name"] = " hibiki";
json["age"] = 24;
//传输
$.ajax({
    type: "Post",
	url: "xxx",
	data: {"me": JSON.stringify(json)}, //序列化为字符串,后台接收的属性名要与"me"一致
	...
});

Java后台接收

@PostMapping("/xxx")
@ResponseBody
public void func1(String me){...}
//或者用对象包装,调用Form的getData()读取
Class Form{
	String me;
	//getter和setter
}
public void func1(Form form){...}

Java后台解析

import org.springframework.boot.configurationprocessor.json.JSONObject;

public void func1(Form form){
JSONObject jsonObj = new JSONObject(form.getMe()); //将JSON字符串转为Java的JSON对象
@SuppressWarnings("unchecked")
Iterator<String> keys = (Iterator<String>) jsonObj.keys(); //取出json的所有key
//遍历key-value
while(keys.hasNext()) {
 	String key = keys.next().toString();
 	String value = jsonObj.get(key).toString();
	//...对每一个键值对进行操作
   }
}
