S2SH框架集成详解(Struts 2.3.16 + Spring 3.2.6 + Hibernate 3.6.10)

近期集成了一次较新版本的s2sh,出现了不少问题,网上资料也是良莠不齐,有的甚至就是扯淡,简单的把jar包扔进去就以为是集成成功了,在这里整理一下详细的步骤,若哪位有什么不同看法,可以留言,欢迎批评改正。

首先说下集成的环境,Eclipse 4.4,Tomcat 7.0.54,Struts2.3.16,Hibernate3.6.10,Spring3.2.6

相关JAR包已上传至百度云:http://pan.baidu.com/s/1pJluA5l

  • 搭建Struts2框架

    1. 创建Java Web工程SSH

    2. 添加struts2.3.16的8个基本类库,可能以前版本是6个,但是2.3.16版本本人测试是8个,大家可以自己测试下

      

    3. 在src下创建config.struts包,并创建struts2的配置文件struts.xml

    4. 在web.xml文件中添加过滤器

 1 <filter> 2     <filter-name>struts2</filter-name> 3     <filter-class> 4       org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter 5     </filter-class> 6     <init-param> 7         <param-name>config</param-name> 8         <param-value> 9             struts-default.xml,struts-plugin.xml,config/struts/struts.xml10         </param-value>11     </init-param>12 </filter>13 <filter-mapping>14     <filter-name>struts2</filter-name>15     <url-pattern>/*</url-pattern>16 </filter-mapping> 

    5. 向struts.xml中添加如下代码

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE struts PUBLIC    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"    "http://struts.apache.org/dtds/struts-2.3.dtd"><struts>    <package name="ssh" namespace="/" extends="struts-default">                <action name="" class="" method="">            <result name=""></result>        </action>    </package></struts>

    6.  创建以下路径用于测试

        WebContent/Web-INF/jsp/index.jsp

              (Web-INF为安全目录,无法直接访问)

    7. 在src目录下创建action包,用于放置Struts2的Action,然后创建MainAction,用于测试,以及以后的页面跳转,并添加如下代码:

1 package action;2 3 public class MainAction {4 5     public String start(){6         return "start";7     }8 9 }    

    8.  在struts.xml中进行配置

1 <struts>2     <package name="ssh" namespace="/" extends="struts-default">3         <default-action-ref name="index" />4         <action name="index" class="action.MainAction" method="start">5             <result name="start">WEB-INF/jsp/index.jsp</result>6         </action>7     </package>8 </struts>

    9. 启动web服务器,测试http://localhost:8080/SSH/

  • 集成struts2和spring

    1. 添加spring类库

      

    2. 添加strut2集成spring类库:struts2-spring-plugin-2.3.16.3.jar

    3. 添加spring配置文件applicationContext.xml,并添加如下信息

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><beans>    </beans>

    4. 在web.xml文件中添加spring监听器,在filter标签外

1 <listener>  2   <listener-class>  3     org.springframework.web.context.ContextLoaderListener  4     </listener-class>  5 </listener>6 <context-param> 7     <param-name>contextConfigLocation</param-name> 8     <param-value> classpath:config/spring/applicationContext.xml </param-value> 9 </context-param>

    5. 启动Tomcat测试

    6. spring管理struts2中Action,在spring文件中配置

<bean id="mainAction" class="action.MainAction"></bean>

    7. 修改struts对应配置文件信息,换成spring配置文件中<bean id="mainAction">

<struts>     <package name="ssh" namespace="/" extends="struts-default">         <default-action-ref name="index" />         <action name="index" class="mainAction" method="start">             <result name="start">WEB-INF/jsp/index.jsp</result>         </action>     </package></struts>

    8. 重启tomcat测试是否可用

  • 集成hibernate

    1. 添加hibernate必须的jar包

      

    2. 添加hibernate配置文件,位置设置在config/hibernate/cfg目录下,文件名:hibernate.cfg.xml,并向其中添加如下配置

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-configuration PUBLIC    "-//Hibernate/Hibernate Configuration DTD 3.0//EN"    "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration>  <session-factory></session-factory></hibernate-configuration

    3. 创建包hibernate.hbm,用于存放hibernate的映射文件,创建User.hbm.xml并添加如下信息

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-mapping PUBLIC     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><hibernate-mapping></hibernate-mapping>

    4. 配置spring的数据源,添加Tomcat JDBC POOL连接池类库

      

    5. 在spring配置文件中配置连接池,在src目录下创建properties包,用于存属性文件,并创建文件db.properties,用于保存数据库连接池的配置属性之后向db.properties中添加数据库连接池的属性数据,包括:url、driver、username、password、initialSize、maxActive、maxIdle、minIdle、maxWait、removeAbandoned、 removeAbandonedTimeOut等

<bean id="PropertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  <property name="location" value="classpath:config/properties/datasource.properties" /></bean>    <bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource" >  <property name="driverClassName" value="${driver}" />  <property name="url" value="${url}" />  <property name="username" value="${username}" />  <property name="password" value="${password}" />          <property name="initialSize" value="${initialSize}" />  <property name="maxActive" value="${maxActive}" />  <property name="maxIdle" value="${maxIdle}" />  <property name="minIdle" value="${minIdle}" />  <property name="maxWait" value="${maxWait}" />  <property name="removeAbandoned" value="${removeAbandoned}" />  <property name="removeAbandonedTimeout" value="${removeAbandonedTimeout}" /></bean>

    6. 在spring中完全管理hibernate配置,删除hibernate.cfg.xml,在spring配置文件中创建id为sessionFactory的bean

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">  <property name="dataSource" ref="dataSource" />  <property name="hibernateProperties">    <props>      <prop key="hibernate.dialect">        org.hibernate.dialect.MySQLDialect      </prop>      <prop key="hibernate.format_sql">true</prop>      <prop key="hibernate.show_sql">true</prop>
    </props>  </property>  <property name="mappingLocations">    <list>      <value>classpath:config/hibernate/User.hbm.xml</value>    </list>  </property></bean>

    7. 创建User实体类,UserDao、jsp等,并在spring中配置提供注入,进行测试

附:sping事务配置(基于tx、aop声明式)

    1. 在spring配置文件中添加声明

<beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:p="http://www.springframework.org/schema/p"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:aop="http://www.springframework.org/schema/aop"     xmlns:tx="http://www.springframework.org/schema/tx"    xsi:schemaLocation="http://www.springframework.org/schema/beans         classpath:/org/springframework/beans/factory/xml/spring-beans-3.2.xsd        http://www.springframework.org/schema/context         classpath:/org/springframework/context/config/spring-context-3.2.xsd        http://www.springframework.org/schema/tx         classpath:/org/springframework/transaction/config/spring-tx-3.2.xsd        http://www.springframework.org/schema/aop        classpath:/org/springframework/aop/config/spring-aop-3.2.xsd">

    2. 添加事务配置,bean标签之外,beans标签之内

<tx:advice id="txAdvice" transaction-manager="transactionManager">  <tx:attributes>    <tx:method name="find*" read-only="false"/>    <tx:method name="add*" rollback-for="Exception"/>  </tx:attributes></tx:advice><aop:config>  <aop:pointcut id="serviceMethod" expression="execution(* action.*.*(..))"/>  <aop:advisor pointcut-ref="serviceMethod" advice-ref="txAdvice"/></aop:config>
