基于Java的Json文件解析

Json文件:

{
    "policies": [
        {
            "planCode": "STR",
            "planName": [
                {
                    "language": "EN",
                    "description": "TravelSurance"
                },
                {
                    "language": "TC",
                    "description": "旅遊萬全保"
                },
                {
                    "language": "SC",
                    "description": "旅游万全保"
                }
            ],
            "involvedParties": [
                {
                    "involvedPartyRole": [
                        "Owner"
                    ],
                    "fullName": ""
                }
            ],
            "policyDetailsIndicator": true
        }
    ]
}

代码:

package com.utils;

import net.minidev.json.JSONArray;
import net.minidev.json.JSONObject;
import net.minidev.json.parser.JSONParser;
import net.minidev.json.parser.ParseException;
import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.util.HashMap;
import java.util.Map;

public class FileParseJson {
    private static Logger logger = LoggerFactory.getLogger(FileParseJson.class);
    public static final String PROPERTY_FILE_PATH = "src/test/resources/UserProfiles/APIResponse.json";
    public static JSONParser parser = new JSONParser();
    Map<String, String> map = new HashMap<>();

    @Test
    public void readJsonFile() throws FileNotFoundException, ParseException {
        Object obj = parser.parse(new FileReader(PROPERTY_FILE_PATH));
        JSONObject jsonObject = (JSONObject) obj;
        JSONArray policiesfields = (JSONArray) jsonObject.get("policies");
        for(Object test : policiesfields){
            JSONObject field = (JSONObject) test;
            String planCodeValue = (String) field.get("planCode");
            System.out.println("planCode :" + planCodeValue);
            JSONArray planNameArray = (JSONArray) field.get("planName");
            for(Object test1 : planNameArray){
                JSONObject field1 = (JSONObject) test1;
                String value = (String) field1.get("description");
                map.put("description",value);
                logger.info(map.toString());
            }
        }
    }
}

运行结果:
