java中JSONArray、List互相转换

1、JSONArray转List

JSONArray字符串 转 List

1 2 3 4 5 6 7 8 9

//初始化JSONArray JSONArray 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

1 2 3 4 5 6 7 8

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

Body.class代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

/** *测试实体类 **/ 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}]

2：List转JSONArray

1 2	List list = new ArrayList(); JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(list));
