5 ways to read and configure springboot (4): read through application.yml

4. Read through application.yml:

/**
 * 学生实体类
 * Created by ASUS on 2018/5/4
 */
@Component("Student")
public class Student {
    @Value("${student.name}")
    private String name;
@Value("${student.age}")
    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;
    }

    public Student(String name, int age) {
        this.name = name;
        this.age = age;
    }

    public Student() {
    }

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

/**
 * springboot startup class
 *
 */
 @SpringBootApplication
 //Read application.yml in the resources directory
 @PropertySource ( "classpath:application.yml" )
 public class Application

{
    public static void main( String[] args )
    {
        ApplicationContext applicationContext= SpringApplication.run(Application.class,args);
        Student student= (Student) applicationContext.getBean(Student.class);
        System.out.println("message:"+student.toString());
}
    


}
