如果方法solrJ.indexAllergenBulkSlor（）中发生任何异常，我需要回滚事务，但它没有回滚事务。我也将AUTOCOMMIT设置为false。请提示帮助。提前谢谢。 这就是我的服务impl看起来的样子
@Service("mcareService")
@Transactional(readOnly = true, value = "oltpTransactionManager")
public class MyServiceImpl implements MyService {
@Override
@Transactional(value = "oltpTransactionManager", propagation=Propagation.REQUIRED, rollbackFor={Exception.class, SolrServerException.class})
public boolean saveAllergens(List<AllergenAutoCmp> allergenList) {
boolean flag = false;
LOGGER.info("Inside saveAllergens in MCareServiceImpl");
try {
allergenAutoCmpRepository.deleteAllergens();
allergenAutoCmpRepository.saveAllergens(allergenList);
solrJ.indexAllergenBulkSlor();
flag = true;
} catch (SolrServerException e) {
LOGGER.error("Error occured while solr indexing Allergens", e);
} catch (IOException e) {
LOGGER.error("Error occured while solr indexing Allergens", e);
}
LOGGER.info("returning from saveAllergens in MCareServiceImpl");
return flag;
}
}

这是因为您捕获了SolrServerException或IOException，但是您没有将其丢弃。如果您了解@Transational如何工作，您将意识到它包装了您的函数周围的代码并尝试捕获RuntimeException。您需要将异常传递给外层。
try {
allergenAutoCmpRepository.deleteAllergens();
allergenAutoCmpRepository.saveAllergens(allergenList);
solrJ.indexAllergenBulkSlor();
flag = true;
} catch (SolrServerException e) {
LOGGER.error("Error occurred while solr indexing Allergens", e);
throw new RuntimeException("SolrServerException occurred! Rollback my transaction.");
} catch (IOException e) {
LOGGER.error("Error occured while solr indexing Allergens", e);
throw new RuntimeException("IOException occurred! Rollback my transaction.");
}

按照建议修改了代码，但仍然没有回滚。
所以而不是
@Override
@Transactional(value = "oltpTransactionManager", propagation=Propagation.REQUIRED, rollbackFor={Exception.class, SolrServerException.class})
public boolean saveAllergens(List<AllergenAutoCmp> allergenList) {
boolean flag = false;
LOGGER.info("Inside saveAllergens in MCareServiceImpl");
try {
allergenAutoCmpRepository.deleteAllergens();
allergenAutoCmpRepository.saveAllergens(allergenList);
solrJ.indexAllergenBulkSlor();
flag = true;
} catch (SolrServerException e) {
LOGGER.error("Error occured while solr indexing Allergens", e);
} catch (IOException e) {
LOGGER.error("Error occured while solr indexing Allergens", e);
}
LOGGER.info("returning from saveAllergens in MCareServiceImpl");
return flag;
}
使用下面的一个（删除try catch）
@Override
@Transactional(value = "oltpTransactionManager", propagation=Propagation.REQUIRED, rollbackFor={Exception.class, SolrServerException.class})
public boolean saveAllergens(List<AllergenAutoCmp> allergenList) {
boolean flag = false;
LOGGER.info("Inside saveAllergens in MCareServiceImpl");
allergenAutoCmpRepository.deleteAllergens();
allergenAutoCmpRepository.saveAllergens(allergenList);
solrJ.indexAllergenBulkSlor();
flag = true;
LOGGER.info("returning from saveAllergens in MCareServiceImpl");
return flag;
}
从控制器调用
@RequestMapping(method = RequestMethod.POST)
@ResponseBody
public boolean handleFileUpload(
@ModelAttribute("uploadFile") MultipartFile uploadFile,
@ModelAttribute("fileType") String fileType) throws Exception {
LOGGER.info("inside handleFileUpload");
CommonsMultipartFile aFile = (CommonsMultipartFile) uploadFile;
boolean flag = false;
if (aFile != null && aFile.getSize() > 0) {
flag = macareService.isFileUploaded(fileType, aFile);
}
LOGGER.info("exiting handleFileUpload");
return flag;
}
和调用saveAllergens（..）方法的服务方法是
@Override
public boolean isFileUploaded(String fileType, CommonsMultipartFile aFile) {
boolean flag = false;
try {
if (MCareConstants.ALLERGEN_UPLOAD_FILETYPE.equals(fileType)) {
ArrayList<AllergenAutoCmp> bulkInsertList = (ArrayList<AllergenAutoCmp>) ExcelUtils
.getBulkInsert(fileType, aFile);
if (bulkInsertList.size() > 0) {
flag = saveAllergens(bulkInsertList);
}
}
if (MCareConstants.REACTION_UPLOAD_FILETYPE.equals(fileType)) {
ArrayList<ReactionAutoCmp> bulkInsertList = (ArrayList<ReactionAutoCmp>) ExcelUtils
.getBulkInsert(fileType, aFile);
if (bulkInsertList.size() > 0) {
flag = saveReactionAutoCmps(bulkInsertList);
}
}
if (MCareConstants.LABTESTS_UPLOAD_FILETYPE.equals(fileType)) {
ArrayList<LabTestAutoCmp> bulkInsertList = (ArrayList<LabTestAutoCmp>) ExcelUtils
.getBulkInsert(fileType, aFile);
if (bulkInsertList.size() > 0) {
flag = saveLabTestAutoCmps(bulkInsertList);
}
}
if (MCareConstants.STAFF_UPLOAD_FILETYPE.equals(fileType)) {
ArrayList<StaffSolrForm> bulkInsertList = (ArrayList<StaffSolrForm>) ExcelUtils
.getBulkInsert(fileType, aFile);
if (bulkInsertList.size() > 0) {
flag = updateStaffList(bulkInsertList);
}
}
if (MCareConstants.REFERRAL_DOCTOR_UPLOAD_FILETYPE.equals(fileType)) {
ArrayList<ReferralAutoLookup> bulkInsertList = (ArrayList<ReferralAutoLookup>) ExcelUtils
.getBulkInsert(fileType, aFile);
if (bulkInsertList.size() > 0) {
flag = saveAllReferralAutolookup(bulkInsertList);
}
}
} catch (HeaderNameNotFoundException e) {
LOGGER.error("Error occured while updating solr indexing");
} catch (MandatoryValueNotFoundException e) {
LOGGER.error("Error occured while updating solr indexing");
}catch (SolrServerException e) {
LOGGER.error("Error updating index : ", e);
}catch (IOException e) {
LOGGER.error("Error updating index : ", e);
}catch (Exception e) {
LOGGER.error("Error occured while saving and solr indexing ReactionAutoCmps", e);
}
return flag;
}
