找不到类 [org.springframework.orm.hibernate5.LocalSessionFactoryBean]答案

【问题标题】：Cannot find class [org.springframework.orm.hibernate5.LocalSessionFactoryBean]找不到类 [org.springframework.orm.hibernate5.LocalSessionFactoryBean]

【问题描述】：

我是 Spring 框架的新手。我正在尝试使用 Spring 4 和 Hibernate 5 设置 Java EE Web 应用程序。但是在服务器上运行应用程序时遇到了以下错误。我整天都在纠结这个问题。请帮我找出问题所在。另外，我在理解Java + Spring + Hibernate 项目的配置方面普遍存在困难。有没有什么好的资料可以解释如何设置bean等。

【问题讨论】：

您的依赖项中有spring-orm 吗？如果是，哪个版本？
@Jens:spring-orm 版本我使用的是 4.2.1.RELEASE。
这应该包含类。可以看看吗？
添加您的 maven pom 而不是 sn-p... 运行 mvn dependency:tree 以查看您的依赖项和版本是什么，而不是认为您使用的是 4.2.x。还有你要部署到哪台服务器上？

【解决方案1】：

在 hibernate.cfg.xml 文件的 <session-factory> 中，

使用<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

代替<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>

并将以下依赖项添加到您的 pom.xml

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-orm</artifactId>
<version>5.1.5.RELEASE</version>

dispatcher-servlet.xml 的 bean 会像，

<bean id="mysessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">  
    <property name="dataSource" ref="ds"></property>  

    <!-- following bean is required only in case of using hbm.xml file, not needed in case of using annotations -->

    <!-- <property name="mappingResources">  
    <list>  
    <value>employee.hbm.xml</value>  
    </list>  
    </property> -->  



    <property name="hibernateProperties">  
        <props>  
            <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>  
            <prop key="hibernate.hbm2ddl.auto">update</prop>  
            <prop key="hibernate.show_sql">true</prop>  

        </props>  
    </property>  
</bean>
