JSON数组到Java对象 [英] JSON Array to Java objects

问题描述

我需要解析一个JSON文件至极看起来是这样的：

I need to parse a json file wich looks like this:

[
  {
    "y": 148, 
    "x": 155
  }, 
  {
    "y": 135, 
    "x": 148
  }, 
  {
    "y": 148, 
    "x": 154
  }
]

和我想要把这些的X坐标和Y坐标成JAVAOBJECT点击，该类看起来像这样：

And I want to put these X-coordinates and Y-coordinates into an JavaObject Click, that class looks like this:

public class Click {
    int x;
    int y;


    public Click(int x, int y) {
        this.x = x;
        this.y = y;
    }

    public int getX() {
        return x;
    }

    public void setX(int x) {
        this.x = x;
    }

    public int getY() {
        return y;
    }

    public void setY(int y) {
        this.y = y;
    }
}

我已经看过GSON，因为他们说，这是戒烟容易，但我不明白我怎么能在我的文件做到这一点。

I have looked at gson because they say it is quit easy but i dont get it how I can do it from my file.

推荐答案

假设你的JSON字符串的数据被存储在一个名为变量 jsonStr ：

assuming your json string data is stored in variable called jsonStr:

String jsonStr = getJsonFromSomewhere();
Gson gson = new Gson();
Click clicks[] = gson.fromJson(jsonStr, Click[].class);
