Objek JSONArray ke Senarai
//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());
Kod Body.class:
/** *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 + '}'; } }
Hasil keluaran:
[{"name":"zhangsan","umur":18}, { "name":"lisi","age":23}]
[Body{name='zhangsan', age=18}, Body{name='lisi', age=23}]
List<T> list = new ArrayList<T>(); JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(list));
