spring batch 任务运行时提示No job configuration with the name解决办法

spring batch 任务运行时提示No job configuration with the name解决办法

开发环境

spring boot

spring batch

idea

jdk8

win7

涉及代码(部分)

启动类:InfrastructureConfiguration.java

@Configuration
@EnableBatchProcessing(modular = true)
public class InfrastructureConfiguration {

@Autowired
JobRepository jobRepository;

@Autowired
public DataSource dataSource;

@Bean
public ApplicationContextFactory flatfileToDbPartitioningJob(){
return new GenericApplicationContextFactory(FlatfilePartitioningJobConfiguration.class);
}
}

job类:FlatfilePartitioningJobConfiguration.java：

@Configuration
public class FlatfilePartitioningJobConfiguration {

@Autowired
private ResourcePatternResolver resourcePatternResolver;

@Autowired
private JobBuilderFactory jobBuilders;

@Autowired
private StepBuilderFactory stepBuilders;

@Autowired
public DataSource dataSource;

@Bean
public Job flatfileToDbPartitioningJob(){
return jobBuilders.get("flatfileToDbPartitioningJob")
//.listener(protocolListener())
.start(partitionStep())
.build();
}

@Bean
public Step partitionStep(){
return stepBuilders.get("partitionStep")
.partitioner(flatfileToDbStep())
.partitioner("flatfileToDbStep", partitioner())
//              .taskExecutor(taskExecutor())
.taskExecutor(new SimpleAsyncTaskExecutor())
.build();
}
}

单元测试类：InfrastructureConfigurationTest.java

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = AellelibBatchApplication.class)
@WebAppConfiguration
public class InfrastructureConfigurationTest {

@Autowired
private JobRegistry jobRegistry;
@Autowired
private JobLauncher jobLauncher;

@Autowired
private Job job;

@Test
public void testFlatfileToDbPartitioningJob() throws NoSuchJobException, JobParametersInvalidException, JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException {
Job job = jobRegistry.getJob("flatfileToDbPartitioningJob");
JobParameters jobParameters = new JobParametersBuilder().addString("flatfileToDbPartitioningJob",""+System.currentTimeMillis()).toJobParameters();
JobExecution jobExecuton = jobLauncher.run(job,jobParameters);
System.out.println(jobExecuton.getEndTime());
}
}

运行InfrastructureConfigurationTest中的testFlatfileToDbPartitioningJob()时报”No job configuration with the name [flatfileToDbPartitioningJob] was registered”的异常，详细如下：

org.springframework.batch.core.launch.NoSuchJobException: No job configuration with the name [flatfileToDbPartitioningJob] was registered

仔细检查代码觉得都没有问题，并且网络上对job的定义都是类似这样定义的：

FlatfilePartitioningJobConfiguration.java:

@Bean
public Job flatfileToDbPartitioningJob(){
return jobBuilders.get("flatfileToDbPartitioningJob")
//.listener(protocolListener())
.start(partitionStep())
.build();
}

折腾了好一阵后，把对job的定义修改成如下就可以了：

把定义的方法名由flatfileToDbPartitioningJob()修改为job()

FlatfilePartitioningJobConfiguration.java:

@Bean
public Job job(){
return jobBuilders.get("flatfileToDbPartitioningJob")
//.listener(protocolListener())
.start(partitionStep())
.build();
}

具体原因不是特别清楚，个人猜测应该是跟spring boot和spring batch job的注册机制有关。若有知道的请赐教。
