如何在春季批处理中同时运行两个作业

Question

我正在尝试使用Spring Batch和Spring Task Scheduler运行两个作业，而与它们的调度时间无关。 这两个作业（Tasklets）在不同的时间间隔执行不同的作业。

以下是springConfig.xml文件：

 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xmlns:batch="http://www.springframework.org/schema/batch" xmlns:task="http://www.springframework.org/schema/batch" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/batch http://www.springframework.org/schema/batch/spring-batch.xsd "> <context:component-scan base-package="com.mythribuswebservice.job,com.mythribuswebservice.job.scheduler" /> <bean id="deleteOldOTPS" class="com.mythribuswebservice.job.tasklet.DeleteOldOTPWeekly"></bean> <bean id="couponToggleActivation" class="com.mythribuswebservice.job.tasklet.CouponToggleActivation"></bean> <batch:job id="otpJob" job-repository="jobRepository"> <batch:step id="step1"> <batch:tasklet ref="deleteOldOTPS"> </batch:tasklet> </batch:step> </batch:job> <batch:job id="couponToggleActivation" job-repository="jobRepository"> <batch:step id="couponActivation"> <batch:tasklet ref="couponToggleActivation"> </batch:tasklet> </batch:step> </batch:job> <bean id="jobRepository" class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean"> <property name="transactionManager" ref="transactionManager" /> </bean> <bean id="transactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" /> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://orcl/mythribus" /> <property name="username" value="root" /> <property name="password" value="root" /> </bean> <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="dataSource" /> </bean> <bean id="jobLauncher" class="org.springframework.batch.core.launch.support.SimpleJobLauncher"> <property name="jobRepository" ref="jobRepository" /> </bean> <bean id="oTPJobScheduler" class="com.mythribuswebservice.job.scheduler.OTPJobScheduler"> </bean> <bean id="couponToggleActivationScheduler" class="com.mythribuswebservice.job.scheduler.CouponToggleActivationScheduler"> </bean> </beans> 

以下是CouponToggleActivationScheduler和OTPJobScheduler的实现：

@EnableAsync

@EnableScheduling公共类CouponToggleActivationScheduler {

@Autowired
JobLauncher jobLauncher;
@Autowired
Job couponToggleActivation;
final JobParametersBuilder jobParametersBuilder=new JobParametersBuilder();

@Scheduled(cron = "*/10 * * * * *")
public void runCouponActivationScheduler() {
    System.out.println("CouponToggleActivationScheduler" + new Date()+"-"+couponToggleActivation.hashCode());
    JobExecution execution;
    jobParametersBuilder.addString("couponToggleActivationScheduler", UUID.randomUUID().toString(), true);

        execution = jobLauncher.run(couponToggleActivation, jobParametersBuilder.toJobParameters());
        System.out.println("Exit Status : " + execution.getStatus());


}

}

---

public class OTPJobScheduler {

@Autowired
JobLauncher jobLauncher;
@Autowired
Job otpJob;
final JobParametersBuilder jobParametersBuilder=new JobParametersBuilder();


@Scheduled(cron = "*/10 * * * * *")
public void runOTPDeleteJob() {
    System.out.println("Ricks...." + new Date()+otpJob.hashCode());
    jobParametersBuilder.addString("otpJobScheduler", UUID.randomUUID().toString(),true);
    JobExecution execution;
        execution = jobLauncher.run(otpJob, jobParametersBuilder.toJobParameters());
        System.out.println("Exit Status : " + execution.getStatus());

}

}

有一些Tasklet可以完成各自的工作：

公共类DeleteOldOTPWeekly实现Tasklet {}

公共类CouponToggleActivation实现Tasklet {}

如果我仅执行一项工作，则一切正常，但是当我安排第二项工作时也会出现异常：

我已经删除了StackTrace。

任何意见。

Answer 1

该错误表明couponToggleActivation没有设置JobRepository。

我认为这是指otpJob作业。

Answer 2

谢谢您的努力。

苦苦挣扎了很长时间之后，我发现宣告couponToggleActivation的Job和Tasklet存在问题。

<batch:job id="couponToggleActivation" job-repository="jobRepository">
    <batch:step id="couponActivation">
        <batch:tasklet ref="couponToggleActivation">

        </batch:tasklet>
    </batch:step>
</batch:job>

我将工作ID和tasklet ref编写为couponToggleActivation，只是更改了为我工作的工作的名称。

问题是IOC容器无法识别Job ID和Tasklet Implementer类引用，并且处于歧义状态。

所以我做到了。

<batch:job id="couponToggleActivationJob" job-repository="jobRepository">
    <batch:step id="couponActivation">
        <batch:tasklet ref="couponToggleActivation">

        </batch:tasklet>
    </batch:step>
</batch:job>
