使用json-org包实现POJO和json的转换

这个jar包把对象转换成json超级舒服，所以顺便记录一下吧

把单个pojo对象转换成json对象

        Student student = new Student("2015551404","熊大");
        JSONObject object = new JSONObject(student);
        System.out.println(object.toString(2));

 

把多个pojo对象转成json数组

        Student student = new Student("2015551404","熊大");
        Student student1 = new Student("2015551405", "孙嘉宁");
        ArrayList<Student> list = new ArrayList<>();
        list.add(student);
        list.add(student1);
        JSONArray array = new JSONArray(list);
        System.out.println(array.toString(2));
