假设我有一个像这样的Yaml文件,
people:
- name : Joe
surname : Barber
age : 16
- name : Andy
surname : Lots
age : 17
我有一个这样的课程,
public class people {
private String name;
private String surname;
private String age;
<!-- With getters and setters -->
}
我如何从Yaml文件中获取人物对象列表? 只是从文件中的键获取值非常简单,但将其映射到对象集合则不是。 我正在使用snakeYaml lib。
