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<String> 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<Body> list = JSONArray.parseArray(jsonArray.toJSONString(), Body.class);
//打印List<Body>
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<T> list = new ArrayList<T>();
JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(list));
