从JSON获取数据

Question

我试图从这个JSON字符串中获取值,但我很难实现这一点.

{"DebugLogId":"1750550","RequestId":"17505503","Result":
{"Code":"","DebugLogId":"1750550","Message":""},
    "Suggestions":[
        {"Ranking":"1","Score":"60","Title":"This is a test message 1"},
        {"Ranking":"2","Score":"60","Title":"This is a test message 2"}         
    ]}

在"建议"中访问数据最简单的方法是什么？我正在使用GSON模块.理想情况下,我想把它全部放在HashMap中.

感谢您的帮助和/或建议!

谢谢你的帮助!

希望这可以帮助:

App.java:

package sg.java.play_sof_json_6596072;

import com.google.gson.Gson;

public class App {
    public static void main(String[] args) {
        Gson gson = new Gson();
        String jsonString = "{\"DebugLogId\":\"1750550\",\"RequestId\":\"17505503\",\"Result\":{\"Code\":\"\",\"DebugLogId\":\"1750550\",\"Message\":\"\"},\"Suggestions\":[{\"Ranking\":\"1\",\"Score\":\"60\",\"Title\":\"This is a test message 1\"},{\"Ranking\":\"2\",\"Score\":\"60\",\"Title\":\"This is a test message 2\"}]}";

        Debug obj = (Debug) gson.fromJson(jsonString, Debug.class);

        System.out.println(obj.getSuggestionList().get(1).getTitle());

    }
}

Debug.java:

package sg.java.play_sof_json_6596072;

import java.util.List;

import com.google.gson.annotations.SerializedName;

public class Debug {
