我正在用 Struts 2、Hibernate 和 Maven 在 Spring 开发一个 Web 应用程序。使用 Maven，我可以成功制作 war 文件，但是当我在 tomcat 7 上部署它时，出现以下错误。
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'myTransactionManager' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Cannot resolve reference to bean 'mySessionFactory' while setting bean property 'sessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mySessionFactory' defined in ServletContext resource [/WEB-INF/classes/applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.MappingException: entity class not found: dto.CityDTO

请有人提出解决方案。
最佳答案
更改为
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configurationClass" value="org.hibernate.cfg.AnnotationConfigurationWithWildcard"/>
<property name="configLocation" value="classpath:hibernate.cfg.xml"/>
</bean>
并添加hibernate.cfg文件:
<!-- connection details -->
<property name="hibernate.dialect">org.hibernate.dialect.PostgreSQLDialect</property>
<property name="hibernate.connection.driver_class">org.postgresql.Driver</property>
<property name="hibernate.connection.url">jdbc:postgresql://localhost/myDatabase</property>
<property name="hibernate.connection.username">myUser</property>
<property name="hibernate.connection.password">myPass</property>
<!-- @see: http://community.jboss.org/wiki/HibernateCoreMigrationGuide36 -->
<property name="hibernate.jdbc.use_streams_for_binary">false</property>
<!-- mappings for annotated classes -->
<mapping class="dto.CityDTO"/>
<mapping class="dto.EmployeeDTO"/>
</session-factory>
配置部分
<property name="mappingResources">
<list>
<!-- mapping of session factory to dto hibernate -->
<value>dto/CityDTO.hbm.xml</value>
<value>dto/EmployeeDTO.hbm.xml</value>
</list>
正在寻找我认为您没有的 hbm 文件
关于java - org.hibernate.MappingException : entity class not found: dto. CityDTO，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/22924607/
