Gson转换与JSONObject区别

net.sf.json.JSONObject
com.google.gson.Gson

JSONObject在解析的过程中会对get方法进行解析，而Gson不会

例子如下：
 

import net.sf.json.JSONObject;
import com.google.gson.Gson;

public class Demo {
private int a;
private String b;
private String c;
public int getA() {
return a;
}
public void setA(int a) {
this.a = a;
}
public String getB() {
return b;
}
public void setB(String b) {
this.b = b;
}
public String getC() {
this.c= a+b;
return c;
}

public static void main(String[] args) {
Demo demo = new Demo();
demo.setA(1);
demo.setB("bbb");
Gson gson = new Gson();
System.out.println(gson.toJson(demo));

String jsonString = JSONObject.fromObject(demo).toString();
System.out.println(jsonString);
}
}

结果：

{"a":1,"b":"bbb"}
{"a":1,"b":"bbb","c":"1bbb"}
