【中文标题】在 Spring-boot 上将 Spring Batch 与 spring-batch-admin-manager 集成时出错【英文标题】：Error Integrating Spring batch with spring-batch-admin-manager on Spring-boot 【发布时间】：2015-02-27 18:01:22 【问题描述】：我正在尝试使用 spring-boot 嵌入式 tomcat 配置将 spring-batch-admin-manager 与 spring-boot-starter-batch 集成在一起。
但是我有这个我无法确定的错误跟踪：

这是我的 gradle 构建文件：
buildscript

mavenCentral()
maven url 'http://repo.spring.io/milestone/'

classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.0.RELEASE")

jar

exclude module: 'jmxtools'
exclude module: 'jmxri'
*/
testCompile("org.springframework.boot:spring-boot-starter-test")
task wrapper(type: Wrapper)
gradleVersion = '1.11'
我添加了这些配置，如以下 github 示例所示：
https://github.com/codecentric/spring-batch-admin-spring-boot
@Configuration
@ImportResource("classpath:/org/springframework/batch/admin/web/resources/servlet-config.xml")
public class ServletConfiguration
*/
@Configuration
@ImportResource("classpath:/org/springframework/batch/admin/web/resources/webapp-config.xml")
public class WebappConfiguration
这是我的 batchConfiguration 类：
@EnableBatchProcessing
@Configuration
public class BatchConfiguration
private static final Logger logger = LoggerFactory.getLogger(BatchConfiguration.class);
@Inject
WriteToKafkaTasklet writeToKafkaTasklet;
@Autowired
private StepBuilderFactory steps;
@Autowired
private JobBuilderFactory jobs;
@Autowired
private StepBuilderFactory stepBuilderFactory;
我错过了什么？
【问题讨论】：
您是否有示例代码在其中使用 spring-batch-admin 和 spring-batch？谢谢 【参考方案1】：这里有几件事：
-
不要在 Spring Batch Admin 中使用
@EnableBatchProcessing。 SBA 提供了许多开箱即用的组件。如果您愿意使用最新最好的，它提供了@EnableBatchProcessing 提供的所有内容，而无需使用注释。
您获得的堆栈跟踪是因为@EnableBatchProcessing 正在注册一个使用动态子类的StepScope，但Spring Batch Admin 也在注册一个使用java 代理的StepScope。如前所述，删除 @EnableBatchProcessing 应该会删除您的堆栈跟踪。
话虽如此，如果您正在使用当前发布的组件，一旦您删除了@EnableBatchProcessing，您将需要手动配置它提供的两个构建器。将以下 XML 添加到您的覆盖 XML 中，您应该可以做生意了：
<bean id="jobBuilderFactory" class="org.springframework.batch.core.configuration.annotation.JobBuilderFactory">
<constructor-arg ref="jobRepository"/>
</bean>
<bean id="stepBuilderFactory" class="org.springframework.batch.core.configuration.annotation.StepBuilderFactory">
<constructor-arg index="0" ref="jobRepository"/>
<constructor-arg index="1" ref="transactionManager"/>
</bean>
请留意 Spring Batch Admin 2.0。这将包含这里讨论的所有内容。M1 应该会在接下来的几周内推出。
