Error integrating Spring package with spring-batch-admin-manager on spring-boot
I am trying to combine spring-batch-admin-manager with spring-boot-starter-batch together using spring-boot embedded tomcat configuration.
However, I have this error which I cannot nail:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'batchConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.batch.core.configuration.annotation.StepBuilderFactory com.mycompany.notification.processor.service.batch.configuration.BatchConfiguration.steps; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stepBuilders' defined in class path resource [org/springframework/batch/core/configuration/annotation/SimpleBatchConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.batch.core.configuration.annotation.StepBuilderFactory]: Factory method 'stepBuilders' threw exception; nested exception is java.lang.ClassCastException: org.springframework.batch.core.repository.support.JobRepositoryFactoryBean$$EnhancerBySpringCGLIB$$6da887a9 cannot be cast to org.springframework.batch.core.repository.JobRepository

I added these configs as shown in this github example:
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 {
}
this is my batchConfiguration class:
@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;
}
What am I missing?

Several things here:
- Do not use
@EnableBatchProcessing
with Spring Batch Admin. SBA provides several components out of the box. If you want to use the latest and greatest, it provides everything@EnableBatchProcessing
without using annotations. - Stack trace because it
@EnableBatchProcessing
registersStepScope
which uses a dynamic subclass, but Spring Batch Admin also registersStepScope
which uses a java proxy. As mentioned, remove@EnableBatchProcessing
and remove the stack trace.
If you are using currently released components, after uninstallation, @EnableBatchProcessing
you need to manually configure the two creators it creates. Add the following XML to your override XML and you should be in business:
<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>
Keep an eye on Spring Batch Admin 2.0. This will have what is discussed here. M1 should be out in the next couple of weeks.
