@Value获取yml和properties配置参数
Yml:
#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

@value注解获取yml文件中的值问题
在类中使用@Value注解获取yml配置文件中的值时,需要注意:
1、yml文件中,当值为0000
这种类型的值时,需要用双引号将值引起来。
比如:
错误:key=0000
正确:key=“0000”
如果不使用双引号的话,在使用@value注解时,得到的值是0,而不是0000
2、使用@Value注解得到的是null
需要使用@Autowired进行注入,对应类需要加上@Service
以上为个人经验,希望能给大家一个参考,也希望大家多多支持编程网。
