今天有个同事说要我帮他看下怎么把这个定时任务的cron表达式放到配置文件里面去，
1、在类上加注解@Component，交给Spring管理
2、在@PropertySource指定配置文件名称，如下配置，指定放在src/main/resource目录下的application.yml文件
3、配置文件application.yml参考内容如下
application.yml

jobs:
  customDictUpdateTime:
    corn: "0/5 * * * * ?"


@Configuration
@Component
@Slf4j
@PropertySource(value = "classpath:application.yml")
public class QuartzTask {

    @Autowired
    private RedisUtil redisUtil;

    private static boolean startTask = true;

    @PostConstruct
    public void startInit() {
        excuteBusiness();
    }

    //定时任务初始化政务宝自定义词库
   //如果获取不到, 取冒号后面的默认值
    @Scheduled(cron = "${jobs.customDictUpdateTime.corn:0/5 * * * * ?}")
    public void excuteTask() {
        excuteBusiness();
    }

｝

上面说的是yml配置文件，有的同学就说了，那么我用的application.properties文件配置呢？

application.properties

jobs.customDictUpdateTime.corn=0/5 * * * *

import org.springframework.context.annotation.PropertySource;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;


@Configuration
@Component
@Slf4j
@PropertySource(value = "classpath:application.properties")
public class QuartzTask {

    @Autowired
    private RedisUtil redisUtil;

    private static boolean startTask = true;

    @PostConstruct
    public void startInit() {
        excuteBusiness();
    }

    //定时任务初始化政务宝自定义词库
   //如果获取不到, 取冒号后面的默认值
    @Scheduled(cron = "${jobs.customDictUpdateTime.corn:0/5 * * * * ?}")
    public void excuteTask() {
        excuteBusiness();
    }
