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));
