>2.spring整合hibernate

1)spring 配置数据源
    <!--======================配置自动扫描=======================-->
    <context:component-scan base-package="com.ssh.service,com.ssh.dao"/>
  
2)spring 配置自动扫描

    <!--======================配置数据源=======================-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql:///test2?useSSL=false"/>
        <property name="username" value="root"/>
        <property name="password" value="root"/>
    </bean>                                         
    
3)spring 配置hibernate的SessionFactory

    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
        <property name="packagesToScan" value="com.ssh.entity"/>
    </bean>
    
3)spring 配置hibernate的事务管理
     <bean id="txManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
            <property name="sessionFactory" ref="sessionFactory"/>
     </bean>
     <tx:annotation-driven transaction-manager="txManager"/>

>3.spring整合web项目

在web.xml中配置
  <!-- 加载Spring容器 -->
  <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>

>4.springMVC整合web项目

 1)在web.xml中配置
   <!--配置前端控制器-->
   <servlet>
     <servlet-name>SpringMVC1</servlet-name>
     <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     <init-param>
       <param-name>contextConfigLocation</param-name>
       <param-value>classpath:springmvc.xml</param-value>
     </init-param>
   </servlet>
   <servlet-mapping>
     <servlet-name>SpringMVC1</servlet-name>
     <url-pattern>*.do</url-pattern>
   </servlet-mapping>
 
   <!--解决post中文乱码-->
   <filter>
     <filter-name>CharacterEncodingFilter</filter-name>
     <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
     <init-param>
       <param-name>encoding</param-name>
       <param-value>utf-8</param-value>
     </init-param>
   </filter>
   <filter-mapping>
     <filter-name>CharacterEncodingFilter</filter-name>
     <url-pattern>/*</url-pattern>
   </filter-mapping>
   
 2)配置springMVC文件
     <!--=============自动扫描=================================-->
     <context:component-scan base-package="com.ssh.action"/>
 
     <!--============视图解析器 解析jsp 默认使用jstl标签=========-->
     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
         <!--<property name="prefix" value="/WEB-INF/admin/"/>-->
         <!--<property name="suffix" value=".jsp"/>-->
     </bean>
 
 
     <!--==============基于注解配置映射器============================-->
     <mvc:annotation-driven conversion-service="customConversionService">
     </mvc:annotation-driven>
 
     <!-- ==============配置拦截器 =========================== -->
     <mvc:interceptors>
         <mvc:interceptor>
             <mvc:mapping path="/action/**"/>
             <bean class="com.ssh.interceptor.LogInterceptor"/>
         </mvc:interceptor>
     </mvc:interceptors>
 
     <!--=============自定义参数绑定============================-->
     <bean id="customConversionService"
           class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
         <property name="converters">
             <set>
                 <bean class="com.ssh.utils.String2DateTime"/>
             </set>
         </property>
     </bean>
 
     <!--==============支持文件上传=============================-->
     <bean class="org.springframework.web.multipart.commons.CommonsMultipartResolver" id="multipartResolver">
         <property name="maxUploadSize" value="5242880"/>
     </bean>

>5.注意

   <!--hibernate的sessionFactory-->
    <filter>
      <filter-name>SpringOpenSessionInViewFilter</filter-name>
      <filter-class>org.springframework.orm.hibernate5.support.OpenSessionInViewFilter</filter-class>
    </filter>
    <filter-mapping>
      <filter-name>SpringOpenSessionInViewFilter</filter-name>
      <url-pattern>/*</url-pattern>
    </filter-mapping>
