NoSuchBeanDefinitionException:JobLauncherTestUtils型の修飾Beanはありません
official Spring batch unit testing guideに従って、標準の単体テストケースを作成します。
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:spring/batch/jobs/job-abc.xml", "classpath:spring/batch/config/context.xml"}) public class AppTest { @Autowired private JobLauncherTestUtils jobLauncherTestUtils; @Test public void launchJob() throws Exception { JobExecution jobExecution = jobLauncherTestUtils.launchJob(); assertEquals(BatchStatus.COMPLETED, jobExecution.getStatus()); } }
P.S spring-batch-test.jar
is added to the classpath.
問題
上記のユニットテストを起動すると、JobLauncherTestUtils
にそのようなBeanエラーメッセージはありませんか?
org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.springframework.batch.test.JobLauncherTestUtils com.example.AppTest.jobLauncherTestUtils; ...... org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.batch.test.JobLauncherTestUtils] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. ......

溶液
クラスパスにspring-batch-test.jar
を追加しても、JobLauncherTestUtils
Beanは自動的に作成されません。
これを修正するには、Spring構成ファイルの1つでJobLauncherTestUtils
Beanを宣言します。
spring/batch/config/test-context.xml
そして、単体テストにロードします。
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = { "classpath:spring/batch/jobs/job-abc.xml", "classpath:spring/batch/config/context.xml", "classpath:spring/batch/config/test-context.xml"}) public class AppTest { @Autowired private JobLauncherTestUtils jobLauncherTestUtils; @Test public void launchJob() throws Exception { JobExecution jobExecution = jobLauncherTestUtils.launchJob(); assertEquals(BatchStatus.COMPLETED, jobExecution.getStatus()); } }
