@Value如何获取yml和properties配置参数

#定时任务配置    
application:  
    xxl: 
      job: 
        enabled: true
        admin: 
          addresses: http:///yusp-job-admin/  #127.0.0.1:8080指网关ip:port，yusp-job-admin为调度中心服务名称。通过网关，注册到微服务的/api/server接口，完成注册动作
        executor:          
          appname: af_job   #执行器名称，要求务必唯一
          ip: 10.21.126.237  #执行器IP [选填]：默认为空表示自动获取IP，多网卡时可手动设置指定IP
          port: 9097          #调度中心给微服务发送任务，通过此端口发送指令
          logpath: D:/temp    #执行器日志文件路径
          logretentiondays: 3  # 本地日志保存天数，-1为永远保存
