在Spring启动时将Spring批处理与Spring批处理管理器集成时出错

我正在尝试使用SpringBoot嵌入式tomcat配置将SpringBatch管理器与SpringBootStarter批集成在一起

但是，我有一个我无法确定的错误跟踪：

我添加了这些配置，如github示例所示：

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？

这里有几件事：

不要将

@EnableBatchProcessing

用于Spring批处理管理。SBA提供了许多现成的组件。如果您愿意使用最新和最好的，它将提供

@enablebackprocessing

提供的一切，而无需使用注释

您得到的堆栈跟踪是因为

@EnableBatchProcessing

正在注册一个使用动态子类化的

StepScope

，而Spring Batch Admin也在注册一个使用java代理的

StepScope

。如前所述，删除

@EnableBatchProcessing

，这将删除堆栈跟踪

也就是说，如果您使用的是当前发布的组件，那么一旦删除了

@EnableBatchProcessing

，您就需要手动配置它提供的两个构建器。将以下XML添加到覆盖XML中，您就可以开始工作了：

<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>

---

密切关注SpringBatch Admin2.0。这将包含这里讨论的所有内容。M1将在接下来的几周内发布。

请看一下谢谢。您是否有spring batch admin和spring batch的示例代码？谢谢

@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;


}

<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>
