在Spring項目中使用DataSource和sessionFactory進行Hibernate註釋

我想在Spring的Web應用程序中使用Hibernate的註釋和數據源，但是出現「NoSuchBeanDefinitionException」錯誤，我不知道爲什麼。從我的角度來看都是正確的......如果有人能幫助我解決它，它是非常好的，我:)在Spring項目中使用DataSource和sessionFactory進行Hibernate註釋

這是我的根的context.xml

和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NewsService類實現：

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); 
    } 
}

和接口：

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); 
    }

調度-的servlet：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

</beans> 

<!-- ViewResolver class : org.springframework.web.servlet.view.UrlBasedViewResolver -->

非常感謝解決我的問題:)

幽默我一秒鐘，請嘗試更改組件掃描到'fot.manager.service.impl'而不是'fot.manager.service'。我知道當你指定一個單獨的父對象時（字符串中沒有逗號），Spring將掃描所有的子對象包，但是如果在你有多個包的情況下同樣適用，我無法從文檔中找出 – geoand

我不知道這個語法是有效的（至少在doc我不能找到它）：

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

我認爲你正在尋找：

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

已經是相同的：/ – Odawin

因爲你已經合格NewsServiceImpl小號使用newsService邏輯名稱的服務註釋，則需要將其與相應的Qualifier註釋匹配，否則Spring將嘗試注入不存在的不合格的NewsService。

@Autowired 
@Qualifier("newsService") 
private NewsService newsService;

或者你可以簡單地刪除邏輯名稱NewsServiceImpl's@Service註釋
