我使用JPA进行Spring Batch过程，我遇到了这个问题：
我有一个
的课程 @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());
}
}
调用经理的tasklet。 stracktrace：

我试图在每个方法中使用此代码，但结果是相同的
@Transactional(noRollbackFor=EmptyResultDataAccessException .class)
我认为问题出现在JobRepository中，但我不知道在事务管理器中需要更改什么。有什么想法吗？
感谢。
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");
}
}
}
