Question

我试图创建一个具有hibernate，spring MVC和spring security的项目...但是在映射实体时它会产生classNotFound异常 ......这是我的代码

MVC-调度-servlet.xml中

＆＃13;

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="

        http://www.springframework.org/schema/context/spring-context-3.0.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <mvc:annotation-driven/>
	<context:annotation-config />
	
	<context:component-scan base-package="com.mkyong.*" />

	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix">
			<value>/WEB-INF/pages/</value>
		</property>
		<property name="suffix">
			<value>.jsp</value>
		</property>
	</bean>

</beans>

＆＃13;

弹簧database.xml

＆＃13;

		<property name="hibernateProperties">

	</bean>

	<bean id="userDao" class="com.mkyong.users.dao.UserDaoImpl">

	</tx:advice>

		<aop:advisor advice-ref="txAdvice" pointcut-ref="userServicePointCut" />
	</aop:config>

</beans>

＆＃13;

例外是

 java.lang.ClassNotFoundException: com.mkyong.users.model.User
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1858)
at org.apache.catalina.loader.WebappClassLoaderBase.loadClass(WebappClassLoaderBase.java:1701)
at org.springframework.util.ClassUtils.forName(ClassUtils.java:255)
at org.springframework.util.ClassUtils.resolveClassName(ClassUtils.java:288)

任何帮助都应该非常感激：）

尝试将SessionFactory bean配置更改为：

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="packagesToScan" value="com.mkyong.users.model"/>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="hibernate.format_sql">true</prop>
                <prop key="hibernate.show_sql">true</prop>
            </props>
        </property>
    </bean>

实体在hibernate中产生classNotFound异常
