Question

以下是我尝试将Hibernate与Spring MVC项目集成并添加Autowired功能时遇到的异常。

例外：

SEVERE：将上下文初始化事件发送给侦听器的异常类的实例 org.springframework.web.context.ContextLoaderListener org.springframework.beans.factory.BeanCreationException：错误创建名为'userBOImpl'的bean：注入自动装配依赖性导致;嵌套异常是 org.springframework.beans.factory.BeanCreationException：不能 autowire字段：private com.inspireme.dao.UserDA O. com.inspireme.boimpl.UserBOImpl.userDAO;嵌套异常是 org.springframework.beans.factory.BeanCreationException：错误创建名为'userDAOImpl'的bean：注入自动装配依赖失败;嵌套异常是 org.springframework.beans.factory.BeanCreationExcep tion：不能 autowire字段：private org.hibernate.SessionFactory com.inspireme.daoimpl.UserDAOImpl.sessionFactory;嵌套异常是 j ava.lang.NoClassDefFoundError：Lorg / hibernate / cache / CacheProvider;

分派器-servlet.xml中

 <!-- Enable Annotation based configuration -->
 <context:annotation-config />

 <!-- Base package -->
 <context:component-scan base-package="com.inspireme." />

 <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix">
        <value>/WEB-INF/jsp/</value>
      </property>
      <property name="suffix">
        <value>.jsp</value>
      </property>
 </bean>

 <!-- Database properties configuration - START -->
 <bean id="propertyConfigurer"
    class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" 
    p:location="WEB-INF/classes/properties/database.properties">
 </bean>
 <!-- Database properties configuration - END -->

 <!-- Accessing DB with available credentials - START -->
 <bean id="dataSource"
    class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"
    p:driverClassName="${jdbc.driverClassName}"
    p:url="${jdbc.databaseurl}" p:username="${jdbc.username}"
    p:password="${jdbc.password}">
 </bean>
 <!-- Accessing DB with available credentials - END -->

<!-- Hibernate Settings - START -->
    <bean id="sessionFactory"
       class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
       <property name="dataSource" ref="dataSource"></property>
       <property name="configLocation">
           <value>classpath:hibernate.cfg.xml</value>
       </property>
       <property name="configurationClass">
           <value>org.hibernate.cfg.AnnotationConfiguration</value>
       </property>
       <property name="hibernateProperties">
           <props>
               <prop key="hibernate.dialect">${jdbc.dialect}</prop>
               <prop key="hibernate.show_sql">true</prop>
           </props>
       </property>
   </bean>
<!-- Hibernate Settings - END -->

 <mvc:resources mapping="/resources/**" location="/resources/inspiremetheme/" />

 <mvc:annotation-driven/>

 <tx:annotation-driven />

 <!-- Start of Autowired beans -->
 <bean id="userBO" class="com.inspireme.boimpl.UserBOImpl"></bean>
 <bean id="userDAO" class="com.inspireme.daoimpl.UserDAOImpl"></bean>
 <!-- End of Autowired beans -->

 <bean id="transactionManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory"></property>
</bean>

hibernate.cfg.xml中

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
    "-//Hibernate/Hibernate Configuration DTD//EN"
    "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
    <session-factory>
        <mapping class="com.inspireme.dto.UserDTO"></mapping>
    </session-factory>
</hibernate-configuration>

控制器类

package com.inspireme.controller;

@Controller
@RequestMapping("/")
public class InspireMeController {

    public ApplicationContext applicationContext;

    private static final Logger LOGGER = Logger.getLogger(InspireMeController.class);

    @Autowired
    private UserBO userBO;

服务类：

package com.inspireme.boimpl;

@Service
public class UserBOImpl implements UserBO {

    private static final Logger LOGGER = Logger.getLogger(UserBOImpl.class);

    @Autowired
    private UserDAO userDAO;

存储库类

package com.inspireme.daoimpl;

@Repository
public class UserDAOImpl implements UserDAO {

    @Autowired
    private SessionFactory sessionFactory;

为什么我得到此异常，因为所有3个bean都在dispatcher-servlet.xml文件中定义。

我指的是以下source来集成Hibernate。

Answer 1

java.lang.NoClassDefFoundError: Lorg/hibernate/cache/CacheProvider jar丢失了。

你是部分正确..有一个罐子不匹配..如此处所述.. howtodoinjava.com/2013/12/08 / ...但是在添加之后我得到一个错误，“WEB-INF / inspireme-dispatcher-servlet.xml”：调用init方法失败;嵌套异常是java.io.FileNotFoundException：类路径esource [hibernate.cfg.xml]不能被解析为URL因为它不存在“。请查看我的文件夹结构，让我知道如何在这里给出路径。

不完全确定构建在您的情况下如何工作，但请尝试classpath:/hibernate/hibernate.cfg.xml或classpath:hibernate/hibernate.cfg.xml。或者更好地检查部署战争中该文件在WEB-INF/classes内的确切位置。
