SpringBoot配置读取yaml文件

方式1：@value注解

school:
 name: shcool1
 student:
  zyk: zyk

@RestController
public class Demo1Controller {
    @Value("${school.student.zyk}")
    public String name;

    @RequestMapping("/hello")
    public String getName() {
        return name;
    }
}

方式2：

使用@configurationproperites注解

我想获得的是school.name 和school.student  

@configurationproperites  的+ 类的变量名，就能获取到多级yaml属性

school:
 name: school1
 student: zyk

@Data
@ConfigurationProperties("school")
@Component
public class Demo2pro {
    private String name;
    private String student;
}

@RestController
public class Demo2Controller {
    @Autowired
    Demo2pro demo2pro;
    @RequestMapping("/hello2")
    public String getName() {
        return demo2pro.getName()+demo2pro.getStudent();
    }
}
