Java中JSONArray转换List的方法

JSONArray字符串 转 List

//初始化jsONArrayJSONArray array=new JSONArray();array.add(0,"a");array.add(1,"b");array.add(2,"c"); List list = JSONObject.parseArray(array.toJSONString(),String.class); System.out.println(list.toString());

输出结果：
[a, b, c]

JSONArray对象 转 List实体类对象

//初始化JSONArrayJSONArray jsonArray = JSONArray.parseArray("[{\"name\":\"zhangsan\",\"age\":18},{\"name\":\"lisi\",\"age\":23}]");//打印jsonArraySystem.out.println(jsonArray.toJSONString());//转ListList list = JSONArray.parseArray(jsonArray.toJSONString(), Body.class);//打印ListSystem.out.println(list.toString());

Body.class代码：

static class Body implements Serializable {        private static final long serialVersionUID = 1L;        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;        }        @Override        public String toString() {            return "Body{" +                    "name='" + name + '\'' +                    ", age=" + age +                    '}';        }}

输出结果：
[{“name”:“zhangsan”,“age”:18},{“name”:“lisi”,“age”:23}]
[Body{name=‘zhangsan’, age=18}, Body{name=‘lisi’, age=23}]

List转JSONArray

List list = new ArrayList();JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(list));
