JSONArray字符串 转 List
//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实体类对象
//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：
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}]文章来源：https://www.toymoban.com/news/detail-628501.html
