Java中JSONArray转换List的方法
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}]
List转JSONArray
List<T> list = new ArrayList<T>(); JSONArray jsonArray = JSONArray.parseArray(JSON.toJSONString(list));
