  • jfinal任务调度quartz(cron) 定时任务 QuartzPlugin


    maven导包:
    <properties>
    <quartz.version>2.2.1</quartz.version>
    </properties>
    <dependency>
    <groupId>org.quartz-scheduler</groupId>
    <artifactId>quartz</artifactId>
    <version>${quartz.version}</version>
    </dependency>


    配置文件:
    # vsp timer
    vspDomain.job=com.test.timer.VspTimer
    vspDomain.cron=0 */5 * * * ?
    vspDomain.enable=true

    第一:配置cron配置文件,一般是***.properties格式的文件,里面的配置一般是这种格式的
    xxxx.job=com.job.OneDayJob // 任务调度的类
    xxxx.cron=0 58 23 ? * * // cron表达式 我这个是每天的23:58执行一次
    xxxx.enable=true // 是否开启 true开 false关闭

    第二:编写任务调度类:需要实现quartz的Job接口

    第三、在jfinal config的configPlugin方法中绑定QuartzPlugin插件
    @Override
    public void configPlugin(Plugins me) {

      // 定时任务
      String quartzConfigFile = "***.properties";
      QuartzPlugin quartzPlugin = new QuartzPlugin(quartzConfigFile);
      me.add(quartzPlugin);
    }

    这里需要注意的是 jfinal2.2 已经没有logger了,如果直接使用会报找不到文件错误,这里需要复写QuartzPlugin类

    然后重启下服务,定时任务就开跑了。
