spring - 在 Spring 项目中使用 DataSource en sessionFactory 的 Hibernate 注释

标签 spring hibernate spring-mvc

我试图在我的 Spring web 应用程序中使用 Hibernate 的注释和数据源，但我有一个错误“NoSuchBeanDefinitionException”，我不知道为什么。从我的角度来看，一切都是正确的......如果有人可以帮助我解决它，那对我来说非常好:)

这是我的 root-context.xml

Java 文件:

package fot.manager.ajax;

import java.util.Collection;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

import fot.manager.model.News;
import fot.manager.service.NewsService;

@Controller

@RequestMapping("/ajax")

public class jqGridController {

    @Autowired
    private NewsService newsService;

    // Contrôleur pour afficher les news
    @RequestMapping("/getNews")
    @ResponseBody
    public Collection<News> getNews(){
        Collection<News> listNews = newsService.getAllNews();

        for (News news : listNews){
            System.out.println(news.getAuteur().getPseudo());
        }

        return listNews;
    }
}

我的 NewsService 类实现:

    package fot.manager.service.impl;

import java.util.Collection;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import fot.manager.dao.NewsDao;
import fot.manager.model.News;
import fot.manager.service.NewsService;

@Service("newsService")
@Transactional
public class NewsServiceImpl implements NewsService {

    @Autowired
    private NewsDao newsDao;

    @Override
    public Collection<News> getAllNews() {
        return newsDao.getAllNews();
    }

    @Override
    public News getNewsById(int id) {
        return newsDao.getNewsById(id);
    }

    @Override
    public News editNews(News news) {
        return newsDao.editNews(news);
    }

    @Override
    public News deleteNews(int id) {
        return newsDao.deleteNews(id);
    }
}

界面:

 package fot.manager.service;

import java.util.Collection;

import fot.manager.model.News;

    public interface NewsService {
        Collection<News> getAllNews();
        News getNewsById(int id);
        News editNews(News news);
        News deleteNews(int id);
    }

非常感谢解决我的问题:)

最佳答案

我不确定这个语法是否有效(至少我在文档中找不到它):

<context:component-scan base-package="fot.manager.service, fot.manager.dao" />

我认为您正在寻找:

<context:component-scan base-package="fot.manager">
    <context:include-filter type="regex" expression=".*\.service\..*"/>
    <context:include-filter type="regex" expression=".*\.dao\..*"/>
</contextn:component-scan>
