应用程序启动但出现此异常

Exception in thread "main" org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'jobLauncher' available
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:687)
    at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1207)
    at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:284)
    at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:197)
    at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1081)
    at com.hms.ar.batch.job.ARBatchJobApplication.main(ARBatchJobApplication.java:55)

我尝试在资源文件夹下创建spring.xml 并定义JobLauncher bean。仍然有同样的例外

我试图@Autowire这个bean。仍然有相同的异常

我主要方法中的一些代码

public static void main(String[] args) {
        savedArgs = args;
        String jobName = processParameters(args);
        ApplicationContext ctx = configureApplication(new SpringApplicationBuilder()).run(args);
        JobLauncher jobLauncher = (JobLauncher) ctx.getBean("jobLauncher");
        JobExplorer jobExplorer = (JobExplorer) ctx.getBean("jobExplorer");
        Job job = (Job) ctx.getBean(jobName);

}

我希望我的工作能够开始，但是由于这个异常而没有开始

将@EnableBatchProcessing添加到您的配置类之一。

https://docs.spring.io/spring-batch/trunk/reference/html/configureJob.html

@EnableBatchProcessing的工作方式与Spring系列中的其他@ Enable *注释类似。在这种情况下，@ EnableBatchProcessing提供了用于构建批处理作业的基本配置。在此基本配置中，除了提供许多可自动装配的bean之外，还创建了StepScope实例：


JobRepository-Bean名称“ jobRepository”

JobLauncher-Bean名称为“ jobLauncher”

JobRegistry-Bean名称为“ jobRegistry”

PlatformTransactionManager-Bean名称为“ transactionManager”

JobBuilderFactory-Bean名称“ jobBuilders”

StepBuilderFactory-Bean名称为“ stepBuilders”

获取没有名为“ jobLauncher”的bean可用异常
