如何在 Spring 季批次中同时运行两个作业-Java 学习之路

我正在尝试使用Spring Batch和Spring Task Scheduler运行两个作业而不管它们的调度时间 . 这两个作业（Tasklet）都在不同的时间间隔执行不同的工作 .

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"

	">
	<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"

		<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"

	<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());

}

}

有些Tasklet在那里做各自的工作：

公共类DeleteOldOTPWeekly实现Tasklet {}

公共类CouponToggleActivation实现Tasklet {}

If i am running only one job the things work fine.but when i schedule the second too it gives exception:

我删除了StackTrace .

任何评论都会很明显 .

该错误表明couponToggleActivation没有JobRepository设置 .

我认为这是指otpJob工作 .

谢谢..为你的努力 .

经过很长一段时间的努力，我能够发现声明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>

我已经编写了job id和tasklet ref作为couponToggleActivation，只是更改了为我工作的工作名称 .

问题是IOC容器无法识别Job id和Tasklet Implementer类ref并且处于Ambiguity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>
