如何从application.yaml导入Bean映射值

@ConfigurationProperties(prefix = "myapp")
public class MyAppConfig {
    private String name;
    private int age;
    // 其他属性
    
    // 省略getter和setter方法
}

myapp:
  name: My Application
  age: 20
  # 其他属性

@SpringBootApplication
@EnableConfigurationProperties(MyAppConfig.class)
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

@Service
public class MyService {
    @Autowired
    private MyAppConfig myAppConfig;
    
    // 使用配置值
    public void doSomething() {
        String name = myAppConfig.getName();
        int age = myAppConfig.getAge();
        // 其他操作
    }
}
