NoSuchBeanDefinitionException: Keine qualifizierende Bean vom Typ JobLauncherTestUtils
Befolgen Sie dieofficial Spring batch unit testing guide, um einen Standard-Unit-Testfall zu erstellen.
@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.
Problem
Beim Start über dem Komponententest wirdJobLauncherTestUtils keine solche Bean-Fehlermeldung angezeigt.
org.springframework.beans.factory.BeanCreationException: Could not autowire field:
private org.springframework.batch.test.JobLauncherTestUtils com.example.AppTest.jobLauncherTestUtils;

Lösung
Durch Hinzufügen vonspring-batch-test.jar zum Klassenpfad wird dieJobLauncherTestUtils-Bean nicht automatisch erstellt.
Um dies zu beheben, deklariert eineJobLauncherTestUtils-Bean in einer Ihrer Spring-Konfigurationsdateien.
spring/batch/config/test-context.xml
Und lädt es in den Unit-Test.
@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());
}
}
