Spring、Hibernate、Struts 的整合
记一下 SSH 是怎么整合的，省得以后老是百度。
applicationContext.xml要复制一份放在 Tomcat 的 bin 目录下，否则会找不到。
然后这时候要包一下 Hibernate 的配置文件。
贴一份模板
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
<property name="configLocations">
<value>classpath:hibernate.cfg.xml</value>
</property>
</bean>
<bean id="loginDAO" class="org.DAO.LoginDAOImpl">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
</beans>
web.xml是 IDEA 自己生成的，随便贴一下。

struts.xml的配置也不变。
