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>
