1. 项目结构图

2. TestTimer.Java 代码
package test;
import org.springframework.stereotype.Repository;
@Repository(value = "dispatchService")
public class TestTimer {
public static int timer = -1;
protected void executeInternal() {
timer++;
System.out.println(timer);
}
}
3. web.xml配置

7. jar 包结构

8.执行结果

附件上传工程的时候 老是卡着出错......

本文详细介绍了使用Spring框架进行应用开发时的配置细节,包括项目结构、类的注解使用、web.xml配置、定时任务配置文件以及相关jar包结构。通过实例展示了如何在项目中实现定时任务的自动化执行。
