NoSuchBeanDefinitionException:JobLauncherTestUtils型の修飾Beanがありません

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:

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());

    }
}
