从 JSON 获取数据

2022-01-08 00:00:00 json hashmap java map gson

我正在尝试从这个 JSON 字符串中获取值，但我很难做到这一点.

I'm trying to get the values out of this JSON string but I'm having a hard time achieving this.

{"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"}         
    ]}

什么方法最容易访问建议"中的数据?我正在使用 GSON 模块.理想情况下，我想把它全部放在一个 HashMap 中.

What way would be easiest to access the data in 'Suggestions'? I'm using the GSON module. Ideally I would like to put it all in a HashMap.

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:

Debug.java:

package sg.java.play_sof_json_6596072;

import java.util.List;

import com.google.gson.annotations.SerializedName;

public class Debug {
    @SerializedName("DebugLogId")
    private String debugLogId;
    @SerializedName("RequestId")
    private String requestId;
    @SerializedName("Result")
    private Result result;
    @SerializedName("Suggestions")
    private List<Suggestion> suggestionList;

    /**
     * @return the debugLogId
     */
    public final String getDebugLogId() {
        return this.debugLogId;
    }

    /**
     * @param debugLogId the debugLogId to set
     */
    public final void setDebugLogId(String debugLogId) {
        this.debugLogId = debugLogId;
    }

    /**
     * @return the requestId
     */
    public final String getRequestId() {
        return this.requestId;
    }

    /**
     * @param requestId the requestId to set
     */
    public final void setRequestId(String requestId) {
        this.requestId = requestId;
    }

    /**
     * @return the result
     */
    public final Result getResult() {
        return this.result;
    }

    /**
     * @param result the result to set
     */
    public final void setResult(Result result) {
        this.result = result;
    }

    /**
     * @return the suggestionList
     */
    public final List<Suggestion> getSuggestionList() {
        return this.suggestionList;
    }

    /**
     * @param suggestionList the suggestionList to set
     */
    public final void setSuggestionList(List<Suggestion> suggestionList) {
        this.suggestionList = suggestionList;
    }

}

结果.java:

package sg.java.play_sof_json_6596072;

import com.google.gson.annotations.SerializedName;

public class Result {
    @SerializedName("Code")
    private String code;
    @SerializedName("DebugLogId")
    private String debugLogId;
    @SerializedName("Message")
    private String messahe;

    /**
     * @return the code
     */
    public final String getCode() {
        return this.code;
    }

    /**
     * @param code the code to set
     */
    public final void setCode(String code) {
        this.code = code;
    }

    /**
     * @return the debugLogId
     */
    public final String getDebugLogId() {
        return this.debugLogId;
    }

    /**
     * @param debugLogId the debugLogId to set
     */
    public final void setDebugLogId(String debugLogId) {
        this.debugLogId = debugLogId;
    }

    /**
     * @return the messahe
     */
    public final String getMessahe() {
        return this.messahe;
    }

    /**
     * @param messahe the messahe to set
     */
    public final void setMessahe(String messahe) {
        this.messahe = messahe;
    }

}

Suggestion.java:

Suggestion.java:

package sg.java.play_sof_json_6596072;

import com.google.gson.annotations.SerializedName;

public class Suggestion {
    @SerializedName("Ranking")
    private String ranking;
    @SerializedName("Score")
    private String score;
    @SerializedName("Title")
    private String title;

    /**
     * @return the ranking
     */
    public final String getRanking() {
        return this.ranking;
    }

    /**
     * @param ranking the ranking to set
     */
    public final void setRanking(String ranking) {
        this.ranking = ranking;
    }

    /**
     * @return the score
     */
    public final String getScore() {
        return this.score;
    }

    /**
     * @param score the score to set
     */
    public final void setScore(String score) {
        this.score = score;
    }

    /**
     * @return the title
     */
    public final String getTitle() {
        return this.title;
    }

    /**
     * @param title the title to set
     */
    public final void setTitle(String title) {
        this.title = title;
    }

}
