配置 Spring 定时任务

第一种方式

首先在配置文件头部必须要有：

xmlns:task="http://www.springframework.org/schema/task"
​

其次 xsi:schemaLocation 必须为其添加：

http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task.xsd
​

然后 spring 扫描过程必须涵盖定时任务类所在的目录：

<context:component-scan base-package="com.xx.xx" />
​

com.xx.xx 属于定时任务类的父级甚至更高级

然后设置动作启用定时任务

<task:annotation-driven/>
​

最后设置任务类

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

@Component
@Lazy(value=false)
public class MyQuartzs {

    @Scheduled(cron = "*/5 * * * * ?")//每隔5秒执行一次
    public void test() throws Exception {
        System.out.println("Test is working......");
    }

    //@Scheduled(cron = "0 0 1 * * ?")//每天凌晨1点整
    //@Scheduled(cron = "0 30 0 * * ?")//每天凌晨0点30分
    //@Scheduled(cron = "0 */60 * * * ?")//1小时处理一次
	
}
​
