spring 注解方式配置定时任务

1：spring 配置文件中增加这句

 <task:annotation-driven/>

2：确保扫描程序能够扫描后  下面第3步骤的java类

<context:component-scan base-package="cms"/>

3：AnnotationQuartz.java

package cms;

import base.util.BaseDateUtil;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.util.Date;

/**
 * User: liuwentao
 * Time: 13-10-22 下午3:36
 * 小说城网站欢迎访问: http://www.xiaoshuocity.com
 */
@Component
public class AnnotationQuartz {
    @Scheduled(cron = "0 0/1 15,* * * ?")
    //需要注意@Scheduled这个注解，它可配置多个属性：cron\fixedDelay\fixedRate
    public void test() {
        String dateStr = BaseDateUtil.getFormatString(new Date(), "yyyy-MM-dd HH:mm:ss");
        System.out.println("小说城 www.xiaoshuocity.com 每分钟执行一次:" + dateStr);
    }
}
