我做了一些搜索,但我无法找出问题所在。我知道问题来自 ClassNotFoundException 但我无法解决它。
错误:org.springframework.beans.factory.BeanCreationException:创建名为“applicationController”的bean时出错:注入自动装配的依赖项失败;嵌套异常是 org.springframework.beans.factory.BeanCreationException:无法自动装配字段:私有 com.it.service.applicationService com.it.controller.applicationController.applicationService;嵌套异常是 org.springframework.beans.factory.CannotLoadBeanClassException:无法为 ServletContext 资源 [/WEB-INF/spring-servlet.xml] 中定义的名称为“sessionFactory”的 bean 找到类 [org.springframework.orm.hibernate4.LocalSessionFactoryBean] ; 嵌套异常是 java.lang.ClassNotFoundException: org.springframework.orm.hibernate4.LocalSessionFactoryBean

我自动连接了我需要的一切(嗯,我想)。这是我的代码:
DAO类:
package com.it.dao;
import java.util.List;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import com.it.model.application;
@Repository("applicationDao")
public class applicationDaoImpl implements applicationDao {
@Autowired
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public List<application> listeAll() {
return sessionFactory.getCurrentSession()
.createQuery("from application").list();
}
}
服务等级:
package com.it.service;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.it.dao.applicationDao;
import com.it.model.application;
@Service("applicationService")
public class applicationServiceImpl implements applicationService {
@Autowired
private applicationDao applicationDao;
@Transactional
public List<application> listeAll() {
return applicationDao.listeAll();
}
}
控制器类:
package com.it.controller;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.it.model.application;
import com.it.service.applicationService;
@Controller
@Configuration
@ComponentScan("com.it.service")
public class applicationController {
@Autowired
private applicationService applicationService;
@RequestMapping("/index")
public String listContacts(Map<String, Object> map) {
map.put("application", new application());
map.put("applicationList", applicationService.listeAll());
return "application";
}
}
弹簧-servlet.xml:
<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
p:packagesToScan="com.it"
p:dataSource-ref="dataSource"
/>
<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager" p:sessionFactory-ref="sessionFactory"/>
<!-- Translates Hibernate exceptions to Spring Data Access Exceptions -->
<bean class="org.springframework.orm.hibernate4.HibernateExceptionTranslator"/>
在这里我尝试了几件事,localSessionFactoryBean、annotationfactorybean、hibernate 3 或 4 等。但没有一个工作:(
我也有:
<context:component-scan base-package="com.it.controller" />
<context:component-scan base-package="com.it.dao" />
并且服务应该通过注释进行扫描,但我也尝试在 xml 中声明扫描。
如果有人可以帮助我,那就太好了:) 提前谢谢你,Aure
