異常在JUnit的情況下實現了Spring Batch的

Question

我寫春天批次application.Code JUnit的測試用例下面

@RunWith(SpringJUnit4ClassRunner.class) 
@SpringBootTest(classes = { AppTest.BatchTestConfig.class }) 
public class AppTest { 

    @Autowired 
    private JobLauncherTestUtils jobLauncherTestUtils; 

    @Test 
    public void demo() throws Exception { 
     JobExecution jobExecution = jobLauncherTestUtils.launchJob(); 

     Assert.assertEquals(BatchStatus.COMPLETED, jobExecution.getStatus()); 
    } 

    @Configuration 
    @EnableBatchProcessing 
    static class BatchTestConfig { 

     @Bean 
     JobLauncherTestUtils jobLauncherTestUtils() { 
      return new JobLauncherTestUtils(); 
     } 

    } 
} 

給定，但是相同的是給予例外如下：

org.springframework.beans.factory.UnsatisfiedDependencyException: 
Error creating bean with name 'jobLauncherTestUtils': 
Unsatisfied dependency expressed through method 'setJob' parameter 0; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type 'org.springframework.batch.core.Job' available: 
expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {} 

請建議

這條線：

@SpringBootTest(classes = { AppTest.BatchTestConfig.class })

僅加載您的測試配置，但該配置不包含要測試的Job。您需要包括與classes陣列作業中的配置，例如：

@SpringBootTest(classes = { AppTest.BatchTestConfig.class, MyJobConfig.class })
