JobRepository存储执行期的元数据，提供两种默认实现,一种是存放在内存中,默认实现类为:MapJobRepositoryFactoryBean。在xml中的配置如下:
<bean id="jobRepository"
class="org.springframework.batch.core.repository.support.MapJobRepositoryFactoryBean">
</bean>
另一种是存入数据库中,可以随时监控批处理Job的执行状态,查看Job执行结果是成功还是失败,并且使得在Job失败的情况下重新启动Job成为可能。具体配置如下:
<?xml version="1.0" encoding="UTF-8"?>
