直接读取项目中的yaml文件

☄️ Ideas

package demo.yml;

public class Dog {

    public String name;

    public Integer age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Dog{" +
            "name='" + name + '\'' +
            ", age=" + age +
            '}';
    }
}

dogs:
  - { username: 'zhangsan',age: 12 }
  - { username: 'lisi',age: 13 }
  - { username: 'wangwu',age: 14 }
