我正在使用quartz调度器和cron表达式运行一个批处理作业，但该作业在循环中被多次调用

这里是配置

public static void main(String[] args) {            
        String[] springConfig  = 
            {   
                "classpath:/execs/execJob.xml" 
            };

        ApplicationContext context = new ClassPathXmlApplicationContext(springConfig);       

}

在execJob.xml中-

<import resource="classpath:/schedulers/BatchLaunch.xml" />

在这里，一次又一次地调用微线程。有人能告诉我这里发生了什么吗？

我是否缺少任何配置或有任何错误？

我们遇到了此问题。我们的情况是，我们在applicationContext.xml中配置了一个bean，但我们还使用了：

ApplicationContext context = new ClassPathXmlApplicationContext("/config/applicationContext.xml");

总共有两个bean，所以我们的任务执行两次。最近，我们改变了这一点：

MyBean myBean = (MyBean) BeanUtils.getBean("beanName", MyBean.class);

一切都好

这是海狸：

public final class BeanUtils implements ApplicationContextAware {

private static ApplicationContext applicationContext;

public static Object getBean(String beanName) {
    return applicationContext.getBean(beanName);
}

public static <T> T getBean(String beanName, Class<T> clazs) {
    return clazs.cast(getBean(beanName));
}

public void setApplicationContext(ApplicationContext applicationContext)
        throws BeansException {
    BeanUtils.applicationContext = applicationContext;
}

public static ApplicationContext getApplicationContext() {
    return applicationContext;
}

public final类BeanUtils实现ApplicationContextAware{
私有静态应用上下文应用上下文；
公共静态对象getBean（字符串beanName）{
返回applicationContext.getBean（beanName）；
}
公共静态T getBean（字符串beanName，类CLAZ）{
return clazs.cast（getBean（beanName））；
}
public void setApplicationContext（ApplicationContext ApplicationContext）
抛出BeansException{
BeanUtils.applicationContext=applicationContext；
}
公共静态应用程序上下文getApplicationContext（）{
返回applicationContext；
}

}

希望这有帮助

Opps！！！我在做一件蠢事。这一切都是用cron表达的，

我每秒钟都在安排它。

你能确保

com.abc.scheduler.JobLauncherDetails

类在

springBatchDbContext.xml

和

simpleJobEnvironment.xml

中没有声明为bean吗？不，它没有在那里声明。这两个xml仅包含db和与作业相关的bean。能否请您共享

类路径：/jobs/job.xml

的详细信息？xml包含Tasklet和支持bean，没有其他内容。事实上，当我通过一个主类运行它或从UI触发它时，它可以完美地工作。当我集成quartz来调度作业时，这个问题就开始了。在我的例子中，它被执行了很多次（不是两次或三次），而且我没有多次调用任何bean。感谢您的回复。请使用“0 0/1***？”，每10分钟运行一次。我只是在不知不觉中将*而不是0保留在秒的位置。

MyBean myBean = (MyBean) BeanUtils.getBean("beanName", MyBean.class);

public final class BeanUtils implements ApplicationContextAware {

private static ApplicationContext applicationContext;

public static Object getBean(String beanName) {
    return applicationContext.getBean(beanName);
}

public static <T> T getBean(String beanName, Class<T> clazs) {
    return clazs.cast(getBean(beanName));
}

public void setApplicationContext(ApplicationContext applicationContext)
        throws BeansException {
    BeanUtils.applicationContext = applicationContext;
}

public static ApplicationContext getApplicationContext() {
    return applicationContext;
}
