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：

@Configurationpublic 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)@WebAppConfigurationpublic 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    at org.springframework.batch.core.configuration.support.MapJobRegistry.getJob(MapJobRegistry.java:66)    at com.aellelib.batch.configuration.InfrastructureConfigurationTest.testFlatfileToDbPartitioningJob(InfrastructureConfigurationTest.java:106)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)    at java.lang.reflect.Method.invoke(Method.java:497)    at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50)    at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12)    at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47)    at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17)    at org.springframework.test.context.junit4.statements.RunBeforeTestMethodCallbacks.evaluate(RunBeforeTestMethodCallbacks.java:75)    at org.springframework.test.context.junit4.statements.RunAfterTestMethodCallbacks.evaluate(RunAfterTestMethodCallbacks.java:86)    at org.springframework.test.context.junit4.statements.SpringRepeat.evaluate(SpringRepeat.java:84)    at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:325)    at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:252)    at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.runChild(SpringJUnit4ClassRunner.java:94)    at org.junit.runners.ParentRunner$3.run(ParentRunner.java:290)    at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:71)    at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:288)    at org.junit.runners.ParentRunner.access$000(ParentRunner.java:58)    at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:268)    at org.springframework.test.context.junit4.statements.RunBeforeTestClassCallbacks.evaluate(RunBeforeTestClassCallbacks.java:61)    at org.springframework.test.context.junit4.statements.RunAfterTestClassCallbacks.evaluate(RunAfterTestClassCallbacks.java:70)    at org.junit.runners.ParentRunner.run(ParentRunner.java:363)    at org.springframework.test.context.junit4.SpringJUnit4ClassRunner.run(SpringJUnit4ClassRunner.java:191)    at org.junit.runner.JUnitCore.run(JUnitCore.java:137)    at com.intellij.junit4.JUnit4IdeaTestRunner.startRunnerWithArgs(JUnit4IdeaTestRunner.java:68)    at com.intellij.rt.execution.junit.IdeaTestRunner$Repeater.startRunnerWithArgs(IdeaTestRunner.java:51)    at com.intellij.rt.execution.junit.JUnitStarter.prepareStreamsAndStart(JUnitStarter.java:237)    at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:70)    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)    at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)    at java.lang.reflect.Method.invoke(Method.java:497)    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:147)

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。
