JavaSpring事务性（传播=propagation.REQUIRES_NEW）错误com。太阳代理$Proxy60

Question

使用Spring批处理，我有一个包含2个方法的类。其中一个具有事务性注释。 尝试运行批处理时，我收到一个错误： 自动连线依赖项的注入失败；嵌套的例外是java。lang.IllegalArgumentException:com。太阳代理$Proxy60

背景。xml:

<batch:job id="data-update" parent="raptorBaseJob">
    <batch:step id="load-info" parent="raptorBaseStep">
        <tasklet ref="loadInfoTasklet" />
     <batch:next on="COMPLETED" to="update-info" /> 
    </batch:step>

    <batch:step id="update-info" parent="raptorBaseStep">  
     <tasklet ref="updateInfoTasklet" />  
    </batch:step>
</batch:job> 

loadInfoTasklet。爪哇：

@Component
public class LoadInfoTasklet implements Tasklet {

@Autowired
private InfoManager infoManager;

@Trace
@Override
public RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {    
    try {
        infoManager.load();     
    } catch(Exception ex) {
        stepContribution.setExitStatus(new ExitStatus("FAILED_LOADING"));
    }
    return RepeatStatus.FINISHED;
 }
}

UpdateInfo Tasklet。爪哇：

@Component
public class UpdateInfoTasklet implements Tasklet{

    @Autowired
    private InfoManager infoManager;

    @Trace
    @Override
    public RepeatStatus execute(StepContribution stepContribution, ChunkContext chunkContext) throws Exception {
        try {
            infoManager.update();
        } catch (Exception ex) {
            stepContribution.setExitStatus(new ExitStatus("FAILED"));
        }
        return RepeatStatus.FINISHED;
    }
}

信息经理。爪哇：

@Component
public class InfoManager {

@Autowired
private NameInfo namesInfo;

protected List<String> names;

  @Trace
  public void load() throws Exception {
      names  = namesInfo.getNames();
  }

  @Trace
  @Transactional(propagation=Propagation.REQUIRES_NEW)
    public void update() {
        System.out.println("Updating...");
    }
}
