Question

我在STS中有Roo生成的项目，并尝试自定义更新/删除方法以使用MongoDB（用于级联更新和删除）。我创建了更新（删除）父级时更新（删除）子级的服务方法：

 public class NoteServiceImpl implements NoteService {
    @Autowired
    MongoTemplate mongoTemplate;

    public void updateNotesWithNoteBook(Notebook notebook) {
        Update update = new Update().set("notebook.name", notebook.getName())
                .set("notebook.author", notebook.getAuthor());

        Query query = Query.query(Criteria.where("notebook._id").is(
                new ObjectId(notebook.getId().toString(16))));
        mongoTemplate.updateMulti(query, update, Note.class);
    }
...the similar for delete action

NoteService接口是Roo生成的，如下所示：

@RooService(domainTypes = { org.dp.mongo.shortnotes.domain.Note.class })
public interface NoteService {
}

我从父实体Notebook的Roo控制器* .aj到Notebook控制器类的更新和检测方法的推入重构，并添加了对子服务方法的调用：

@RequestMapping("/notebooks")
@Controller
@RooWebScaffold(path = "notebooks", formBackingObject = Notebook.class)
public class NotebookController {
    @Autowired
    private NoteService noteService;

    @RequestMapping(method = RequestMethod.PUT, produces = "text/html")
    public String update(@Valid Notebook notebook, BindingResult bindingResult,
            Model uiModel, HttpServletRequest httpServletRequest) {
        if (bindingResult.hasErrors()) {
            populateEditForm(uiModel, notebook);
            return "notebooks/update";
        }
        uiModel.asMap().clear();
        notebookService.updateNotebook(notebook);
        **noteService.updateNotesWithNoteBook(notebook);**
        return "redirect:/notebooks/"
                + encodeUrlPathSegment(notebook.getId().toString(),
                        httpServletRequest);
    }

    the similar for delete method...

最后得到错误，noteService没有方法updateNotesWithNoteBook和delete方法。如何修复它们？

Answer 1

NoteService接口中是否存在updateNotesWithNoteBook方法？

你必须将它放在界面中，这就是你从控制器中调用的内容。

Spring Roo / STS：在Controller类中看不到ServiceImpl方法
