   </ filter-mapping  >

Spring

引入spring所需的包：

org.springframework.core-3.1.2.RELEASE.jar

org.springframework.web.struts-3.1.2.RELEASE.jar  

org.springframework.web-3.1.2.RELEASE.jar  

 

 

web.xml中的配置（监听器）：

< context-param >

    < param-name  > contextConfigLocation </  param-name >

    < param-value  > /WEB-INF/classes/applicationContext.xml </ param-value  >

</ context-param >

< listener >

      < listener-class >  org.springframework.web.context.ContextLoaderListener  </ listener-class >

</ listener >

 

 

Hibernate3

 引入所需的包：

hibernate3.jar

hibernate-jpa-2.0-api-1.0.1.Final.jar

javassist-3.12.0.GA.jar

jta-1.1.jar

slf4j-api-1.6.1.jar

dom4j-1.6.1.jar

 

SSH整合

1.spring 整合 struts

一、需要的JAR文件为：Spring和Struts2框架本身需要的JAR文件以及他们所依赖的JAR文件，比如commons-logging.jar等等，另外还需要Struts2发布包中的struts2-spring-plugin-x.xx.jar。

二、在web.xml中增加WebApplicationContext的相应配置，以下两种配置方式本质是一样的。
1.         Servlet 2.3及以上版本可以使用监听器，相应配置如下：
<context-param>
              <param-name>contextConfigLocation</param-name>
              <param-value>/WEB-INF/classes/applicationContext.xml</param-value>
</context-param>
<listener>
              <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
如果spring配置文件被命名为applicationContext.xml，并且放在WEB-INF目录下，则不需要配置<context-param>，因为ContextLoaderListener默认在WEB-INF目录下寻找名为applicationContext.xml的文件。若存在多个Spring配置文件，则在<param-value>中依次列出，之间以逗号隔开。

 

 

2.spring整合hibernate

 

applicationContext.xml如下：

 

<? xml  version = "1.0"  encoding =  "UTF-8" ?>

<! DOCTYPE  beans  PUBLIC

     "-//SPRING//DTD BEAN 2.0//EN"

     "http://www.springframework.org/dtd/spring-beans-2.0.dtd"  >

< beans >

     < bean  id = "sessionfactory"

         class = "org.springframework.orm.hibernate3.LocalSessionFactoryBean"  >

         < property  name = "configLocation"  >

             < value >  classpath:hibernate.cfg.xml </ value  >

         </ property >

       

         < property  name = "dataSource"  >  

              < ref  bean = "dataSource"  />  

       </ property  >

     </ bean  >

   

     < bean  id = "dataSource"  class = "org.springframework.jdbc.datasource.DriverManagerDataSource"  >

         < property  name = "driverClassName"  >

          < value >  com.mysql.jdbc.Driver </ value  >

         </ property >

         < property  name = "url"  >

          < value >  jdbc:mysql://localhost:3306/test </ value  >

         </ property >

         < property  name = "username"  value = "root" ></  property >

         < property  name = "password"  value = "123456" ></  property >

        </ bean >

</ beans >

hibernate.cfg.xml如下：

<! DOCTYPE  hibernate-configuration  PUBLIC

          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"  >

 

  < hibernate-configuration  >

 

      < session-factory  >

 

          <!-- Database connection settings -->

         <!--          <property name="connection.driver_class">com.mysql.jdbc.Driver</property> -->

<!--          <property name="connection.url">jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8</property> -->

<!--          <property name="connection.username">root</property> -->

<!--          <property name="connection.password">123456</property> -->

 

          <!-- SQL dialect -->

          < property  name = "dialect"  > org.hibernate.dialect.MySQLDialect </  property >

 

          <!-- Enable Hibernate's automatic session context management -->

          < property  name = "current_session_context_class"  > thread </  property >

 

          <!-- Echo all executed SQL to stdout -->

          < property  name = "show_sql"  > true </  property >

 

          <!-- Drop and re-create the database schema on startup -->

          < property  name = "hbm2ddl.auto"  > create </  property >

 

          < mapping  resource = "user.xml"  />

 

      </ session-factory  >

 

  </ hibernate-configuration  >
