JSON: Property 'xxx' has no getter method in class 'class xxx'（转）

在做数据转换为JSON格式时：

 

import net.sf.json.JSONArray;

class T{
    private String name;
    private int age;
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
}
public class JSONTest2 {
    public static void main(String[] args) {
        T t = new T();
        t.setName("zhangsan");
        t.setAge(20);

        JSONArray json = JSONArray.fromObject(t);
        System.out.println(json);

        //System.out.println(t.getName());
        //System.out.println(t.getAge());
    }
}

出现了如下错误：

 

thread "main" net.sf.json.JSONException: java.lang.NoSuchMethodException: Property 'age' has no getter method in class 'class T'

原因是 声明bean为public  class 必须是public
