Spring批处理-事务标记为仅回滚

我有一个JPA的Spring批处理流程，我有一个问题：

我有一节课要上

    @Configuration
    public class BeansBatchConfig {

          @Bean(name = "jobRepository")
          public JobRepositoryFactoryBean jobRepository() {

            this.jobRepository = new JobRepositoryFactoryBean();
            this.jobRepository.setDataSource(this.dataSource);
            this.jobRepository.setTransactionManager(this.transactionManager);
            this.jobRepository.setIsolationLevelForCreate(this.isolationLevelForCreate);
            return this.jobRepository;
          }

The manager:

       @Override
  public void saveProjectCategory(ProjectCategoryEto eto) {

    try {
      this.projectCategoryDao.save(getBeanMapper().map(eto, ProjectCategoryEntity.class));
    } catch (DataIntegrityViolationException ex) {
      this.projectCategoryDao.clear();
      LOG.error("Ha habido problemas al insertar el proyecto " + eto.getProject().getCode());
    }
  }

还有给经理打电话的小任务。 stracktrace：

我尝试在每种方法中使用这段代码，但结果是一样的

@Transactional(noRollbackFor=EmptyResultDataAccessException .class)

我认为问题出在JobRepository中，但我不知道必须在事务管理器中更改什么。有什么想法吗

谢谢

使用保存方法更新：

  @Override
  public E save(E entity) {

    if (isNew(entity)) {
      this.entityManager.persist(entity);
      LOG.debug("Saved new {} with id {}.", getEntityName(), entity.getId());
      return entity;
    } else {
      if (this.entityManager.find(entity.getClass(), entity.getId()) != null) {
        E update = this.entityManager.merge(entity);
        LOG.debug("Updated {} with id {}.", getEntityName(), entity.getId());
        return update;
      } else {
        throw new EntityNotFoundException("Entity not found");
      }
    }
  }

你能给我们看看DAO层的findByCode（）吗？我已经更新了代码。对不起，方法是“保存”而不是“按代码查找”，是保存jpa方法。再次检查，谢谢！请给我们展示save（）方法的实现！你找到解决问题的办法了吗？我想我遇到了同样的问题：-P。你能给我们看看DAO层的findByCode（）吗？我已经更新了代码。对不起，方法是“保存”而不是“按代码查找”，是保存jpa方法。再次检查，谢谢！请给我们展示save（）方法的实现！你找到解决问题的办法了吗？我想我遇到了同样的事情：-P。
