1. 导入 SpringBoot 的 snakeyaml 解析包
2. 编写 yaml 文件
3. 编写 yaml 文件对应的 class
4. 编写 main 进行获取

导入 SpringBoot 的 snakeyaml 解析包

<dependency>
    <groupId>org.yaml</groupId>
    <artifactId>snakeyaml</artifactId>
    <version>1.23</version>
</dependency>

编写 yaml 文件

id: 110
name: 'stuName'
gender: '男'
clas:
  id: 110
  name: 'classesName'
  describe: 'describe'

编写 yaml 文件对应的 class

public class Student {

    private Integer id;
    private String name;
    private String gender;

    private Classes clas;

    // getter(), setter(), toString();

}

class Classes {

    private Integer id;
    private String name;
    private String describe;

    // getter(), setter(), toString();

}

编写 main 进行获取

public static void main(String[] args) {

    Yaml yaml = new Yaml();

    Student result = yaml.loadAs(thisClass.class.getClassLoader()
                                 .getResourceAsStream("springboot.yaml"),
                                 Student.class);

    System.out.println(result);

}
