有没有办法正确地集成spring-batch-admin和spring-boot？
根据文档 spring批处理管理员很容易嵌入到现有的应用程序中。 只需复制web.xml和index.jsp，然后添加所需的依赖项即可使其正常工作。
但是，如果我想在现有的春季启动项目中使用它，它会变得更糟。 根据这个例子 ，配置有点hacky但它的工作原理。 我尝试在配置bean中使用@EnableBatchProcessing注释。 然后我得到以下exception。
Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jobBuilders' defined in class path resource [org/springframework/batch/core/configuration/annotation/SimpleBatchConfiguration.class]: Instantiation of bean failed;

我的配置非常简单我有两个配置bean
@Configuration @ImportResource({"classpath:/org/springframework/batch/admin/web/resources/servlet-config.xml", "classpath:/org/springframework/batch/admin/web/resources/webapp-config.xml"}) public class BatchAdminConfiguration { }
和
@Configuration @EnableBatchProcessing public class BatchImporterConfiguration { }
当我删除@EnableBatchProcessing并尝试使用JobBuilderFactory创建作业并使用@StepScope注释时，我正在获取其他ClassCastExceptions。
现在我使用基于xml的配置来创建作业，步骤和其他bean。 它运作良好但我实际上会提供xml免费配置。 有没有办法轻松集成弹簧靴，弹簧批和弹簧批管理？
简短的回答是，您不希望在Spring Batch Admin中使用@EnableBatchProcessing 。 SBA在全球范围内提供了许多@EnableBatchProcessing也提供的bean。 SBA 2.0（目前正在开发中）可能填补当前存在的空间和@EnableBatchProcessing提供的空白（特别是提供JobBuilderFactory和StepBuilderFactory ）。
为了让自己运行，你应该能够（ 我自己还没有厌倦 ）在META-INF/spring/batch/override/目录中配置一个JobBuilderFactory和一个StepBuilderFactory供全局使用。 从那里，您可以在META-INF/spring/batch/jobs目录中使用XML文件，这些文件只对@Configuration类进行组件扫描。 但是，由于bean的重复，请不要使用@EnableBatchProcessing 。
为了记录，这不是Spring Boot问题，因为@EnableBatchProcessing是一个Spring Batch注释，而不是一个Boot。
Spring Batch Admin 2.0-BUILD-SNAPSHOT引入了一个新的Annoation @EnableBatchAdmin ，便于与spring boot集成。 还有一个示例项目https://github.com/spring-projects/spring-batch-admin-samples 。
要完成答案，这里是禁用@EnableBatchProcessing注释后创建两个bean的代码
@Autowired JobRepository jobRepository; @Autowired PlatformTransactionManager transactionManager; @Bean public JobBuilderFactory jobBuilderFactory() { return new JobBuilderFactory(jobRepository); } @Bean public StepBuilderFactory stepBuilderFactory() { return new StepBuilderFactory(jobRepository, transactionManager); }
我在这里有一个基于相同示例的工作版本（我分叉了原始版本）： https ： //github.com/vesperaba/spring-batch-admin-spring-boot 。
我遵循了Michael Minella的建议，并用自定义的覆盖了SpringBatch属性持有者。
我还添加了一份工作来检查它现在是否正常工作
此ClassCastException是由

META-INF/spring/batch/servlet/resources/resource-context.xml
其中包含
这与Spring Java配置类中的mvc配置冲突。 以下类可用于在使用Java配置的现有应用程序中嵌入Spring Batch Admin。

抽象基本菜单也需要单个XML文件，该菜单在Spring Batch Admin项目的其他位置引用。 这是必需的，因为无法从Spring Java配置提供抽象bean。
Maven依赖。 注意确保Maven只提供单个版本的基本Spring框架。
