Spring 为什么是一个；调用事务的回滚"；关于@Transactional注释

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，看起来像：

@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);
    }
}

@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;
}

@覆盖
公共搜索管理员事件搜索（SearchAdminsEvent SearchAdminsEvent）{
Page admins=adminRepository.search（searchAdminsEvent.getSearchTerm（），searchAdminsEvent.getPageRequest（））；
if（admins.getTotalElements（）==0）{
抛出新的SearchedAdminsNotFoundException（searchAdminsEvent.getSearchTerm（））；
}否则{
列出eventAdmins=EventAdmin.newEventAdminsFrom（admins.getContent（））；
返回新的SearchedAdminEvent（searchAdminsEvent.getSearchTerm（）、searchAdminsEvent.getPageRequest（）、eventAdmins）；
}
}

我有一个REST控制器，看起来像：

@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);
    }
}

@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;
}

@RequestMapping（value=“/search”，method=RequestMethod.GET，products=MediaType.APPLICATION\u JSON\u value）
@事务（只读=真）
@应答器
公共响应性搜索（@RequestParam（value=“searchTerm”，required=true）字符串搜索项，@RequestParam（value=“page”，required=true，defaultValue=“0”）int-page，@RequestParam（value=“size”，required=true，defaultValue=“10”）int-size，UriComponentsBuilder）{
HttpHeaders responseHeaders=新的HttpHeaders（）；
Pageable pageRequest=buildPageRequest（页面，大小）；
SearchedAdminEvent SearchedAdminEvent；
试一试{
SearchedAdminEvent=adminService.search（新的SearchAdminsEvent（searchTerm，pageRequest））；
}捕获（SearchedAdminsNotFounde异常）{
返回新的ResponseEntity（responseHeaders，HttpStatus.NOT_FOUND）；
}
responseHeaders.setLocation（builder.path（“/admin/search”）.queryParam（“searchTerm”，searchTerm）。queryParam（“page”，page）。queryParam（“size”，size）。buildAndExpand（searchedAdminEvent.getSearchTerm（））.toUri（））；
列出adminResources=adminResourceAssembler.toResources（searchedAdminEvent.getEventAdmins（））；
ResponseEntity ResponseEntity=新的ResponseEntity（adminResources、responseHeaders、HttpStatus.OK）；
返回响应性；
}

它使用@Transactional（readOnly=true）注释

如果存在此批注，且未找到任何搜索项，则会出现以下异常：
