ssh项目搭建

文中的版本是spring5 hibernate5 struts2.5
maven中添加依赖

在项目的web.xml文件中创建struts的过滤器和spring的监听

<filter>
      <filter-name>struts2</filter-name>
      <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
   <filter-mapping>
       <filter-name>struts2</filter-name>
       <url-pattern>*.action</url-pattern>
   </filter-mapping>
      <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext.xml</param-value>
    </context-param>
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener> 

在项目的resource文件夹中创建applicationContext.xml文件,用来配置spring和struts及spring和hibernate之间的关系

    <!--创建数据源-->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="url" value="jdbc:mysql://localhost:3306/sopping?useUnicode=true&amp;characterEncoding=UTF-8&amp;serverTimezone=UTC"></property>
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="username" value="root"></property>
        <property name="password" value="chen"></property>
    </bean>
        <!--
        创建sessionFactory,为了dao使用
        这里需要注意的是要进行hibernate的配置文件的导入
        还要配置扫描实体类映射文件
        -->
       <!--设置hibernate的属性-->
    <bean id="properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
            <property name="properties" >
                <props>
                    <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                    <prop key="show_sql">true</prop>
                </props>
            </property>
    </bean>
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"></property>
        <property name="hibernateProperties" ref="properties"></property>
        <property name="packagesToScan" value="com.chen.entity"></property>
    </bean>
    <!--配置dao-->
    <bean id="dao" class="com.chen.dao.DaoImpl">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>

在resource中创建struts.xml文件

<struts>
    <package name="default" namespace="/" extends="struts-default">
        <!--struts2.5默认使用通配符不生效,要加入如下配置-->
        <global-allowed-methods>regex:.*</global-allowed-methods>
        <action name="login*" class="loginAction" method="{1}">
            <result name="login">index.jsp</result>
        </action>
    </package>
</struts>

现在我们可以创建相应的包路径

我们的dao如下创建
