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

溶液
クラスパスにspring-batch-test.jarを追加しても、JobLauncherTestUtilsBean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JobLauncherTestUtilsBean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());
}
}
