我对事务REST控制器中的一些异常处理感到困惑。
我有一个管理服务，如下所示：
@Override
public SearchedAdminsEvent search(SearchAdminsEvent searchAdminsEvent) {
Page<Admin> admins = adminRepository.search(searchAdminsEvent.getSearchTerm(), searchAdminsEvent.getPageRequest());
if (admins.getTotalElements() == 0) {
throw new SearchedAdminsNotFoundException(searchAdminsEvent.getSearchTerm());
} else {
List<EventAdmin> eventAdmins = EventAdmin.newEventAdminsFrom(admins.getContent());
return new SearchedAdminsEvent(searchAdminsEvent.getSearchTerm(), searchAdminsEvent.getPageRequest(), eventAdmins);
}
}
我有一个看起来像这样的REST控制器：
@RequestMapping(value = "/search", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
@Transactional(readOnly = true)
@ResponseBody
public ResponseEntity<List<AdminResource>> search(@RequestParam(value = "searchTerm", required = true) String searchTerm, @RequestParam(value = "page", required = true, defaultValue = "0") int page, @RequestParam(value = "size", required = true, defaultValue = "10") int size, UriComponentsBuilder builder) {
HttpHeaders responseHeaders = new HttpHeaders();
Pageable pageRequest = buildPageRequest(page, size);
SearchedAdminsEvent searchedAdminsEvent;
try {
searchedAdminsEvent = adminService.search(new SearchAdminsEvent(searchTerm, pageRequest));
} catch (SearchedAdminsNotFoundException e) {
return new ResponseEntity<List<AdminResource>>(responseHeaders, HttpStatus.NOT_FOUND);
}
responseHeaders.setLocation(builder.path("/admin/search").queryParam("searchTerm", searchTerm).queryParam("page", page).queryParam("size", size).buildAndExpand(searchedAdminsEvent.getSearchTerm()).toUri());
List<AdminResource> adminResources = adminResourceAssembler.toResources(searchedAdminsEvent.getEventAdmins());
ResponseEntity<List<AdminResource>> responseEntity = new ResponseEntity<List<AdminResource>>(adminResources, responseHeaders, HttpStatus.OK);
return responseEntity;
}
它使用@Transactional（readOnly = true）注释。
如果存在此注释，并且未找到任何搜索项，则会出现以下异常：

如果删除注释，则一切正常，响应中包含搜索到的项目。
我想如果没有找到任何搜索项，就会抛出异常，从而触发事务回滚消息。
这是异常处理程序：
@ExceptionHandler(SearchedAdminsNotFoundException.class)
@ResponseBody
public ResponseEntity<ErrorInfo> searchedAdminsNotFoundException(HttpServletRequest request, SearchedAdminsNotFoundException e) {
String url = request.getRequestURL().toString();
String errorMessage = localizeErrorMessage("error.admin.search.not.found", new Object[] { e.getSearchTerm() });
return new ResponseEntity<ErrorInfo>(new ErrorInfo(url, errorMessage), HttpStatus.NOT_FOUND);
}
有没有办法在日志中的某处看到触发事务回滚的内部异常？
我在Spring 3.2.9.RELEASE和Hibernate 3.6.10.Final。
这是根本原因：

更新：这是我的猜测...异常被捕获，因此它不会显示在日志中。即使捕获到异常，注释也会回滚事务。我对吗 ？在这种情况下，如果使用注释，如何处理，即捕获控制器中的异常？
亲切的问候，
Stephane Eybert
答案 0 :(得分：1)
您可以将异常传播给控制器，是的，但我选择将服务方法标记为事务性。我想知道为什么你会抛出异常，但我想这也会有效。另一种选择是处理0值来计算管理员（或者你在该查询中计算的任何值）或大于0的值。意思是，您的服务方法执行查询并返回值。如果它为0，那么您为用户准备了适当的网页，否则为其他东西做准备。
