Kann nicht in SpringBoot-Projekt autuired

Question

Alle Programme sind hier. https://github.com/horitaku1124/spring_batch_sample/tree/master/SpringBatchSample1

Main.java

public class Main { 
    public static void main(String[] args) throws JobExecutionAlreadyRunningException, JobRestartException, JobInstanceAlreadyCompleteException, JobParametersInvalidException { 
     ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); 
     { 
      JobLauncher jobLauncher = context.getBean("jobLauncher", JobLauncher.class); 
      Job job = context.getBean("myJob1", Job.class); 

      JobExecution execution = jobLauncher.run(job, new JobParameters()); 
      System.out.println("Job Exit Status : " + execution.getStatus()); 
     } 
    } 
} 

MyBatchJob.java

public class MyBatchJob implements Tasklet { 
    static Logger logger = Logger.getLogger("MyBatch"); 

    @PersistenceContext(type = PersistenceContextType.EXTENDED) 
    private EntityManager entityManager; 

    @Autowired 
    private SampleTableRepository sampleTableRepo; 

    public RepeatStatus execute(StepContribution arg0, ChunkContext arg1) 
      throws Exception { 
     SampleTableEntity sampleTable = new SampleTableEntity(); 
     sampleTable.setName("test name"); 
     sampleTable.setStatus(100); 
     entityManager.persist(sampleTable); 

     sampleTableRepo.findAll(); 

     System.out.println("Created SampleTableEntity=" + sampleTable.getId()); 
     return RepeatStatus.FINISHED; 
    } 
} 

dieses Main.java ausführen, und ich habe diesen Fehler.

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.example.spring.repository.SampleTableRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} 

EntityManager funktioniert gut. Aber ich habe Fehler beim Autowired SampleTableRepository. Wie soll ich dieses Problem lösen?

Answer 1

Sie sollten Ihr Repository in Ihrem Anwendungskontext definieren, sonst kann Spring es nicht finden.
