整合SSH框架 （Struts2.x+Spring3.x+hibernate3.x+oracle）

整合SSH框架 （Struts2.x+Spring3.x+hibernate3.x+oracle）
1.整合ssh框架思路
1.1 首先需要导入ssh的jar包，包括Struts2，Spring,Hibernate所需jar包和关联包，最后就是oracle的jar包
1.2 然后配置web.xml文件，配置spring的监听器信息,struts2过滤器信息和hibernate的延迟加载问题
1.3 配置Spring的配置文件，首先就是数据源的配置，然后sessionFactory配置，hibernate配置，如果spring使用的是注解，则需要设置spring bean组件扫面,最后配置 实体向SessionFactory的注册映射关系包的路径
1.4 创建pojo，使用spring测试框架的jar里的注解，进行单元测试
2.具体步骤
2.1需要导入的jar包
struts2 :
struts2-core-2.3.16.jar
xwork-core-2.3.16.jar
ognl-3.0.6.jar
Struts2与Spring整合插件包
struts2-spring-plugin-2.3.16.jar
Struts2注解包
struts2-convention-plugin-2.3.16.jar
spring:
spring-aop-3.2.4.RELEASE.jar
spring-aspects-3.2.4.RELEASE.jar
spring-beans-3.2.4.RELEASE.jar
spring-context-3.2.4.RELEASE.jar
spring-core-3.2.4.RELEASE.jar
spring-expression-3.2.4.RELEASE.jar
spring-jdbc-3.2.4.RELEASE.jar
spring-orm-3.2.4.RELEASE.jar
开始启用Spring的测试框架
spring-test-3.2.4.RELEASE.jar
spring-tx-3.2.4.RELEASE.jar
spring-web-3.2.4.RELEASE.jar

其它对于aspect支持包 (AOP)
hibernate:
hibernate3.jar
hibernate-jpa-2.1-api-1.0.0.Final.jar

其它jar包
ojdbc14.jar (oracle的jar)
数据连接池（配置数据源）jar包 :
commons-collections.jar
commons-dbcp.jar
commons-pool-1.6.jar
2.2配置web.xml文件

<?xml version="1.0" encoding= "UTF-8"?><web-app version="2.5"       xmlns="http://java.sun.com/xml/ns/javaee"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xsi:schemaLocation="http://java.sun.com/xml/ns/javaee      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" >       <!-- 处理Hibernate延迟加载问题 -->       <filter>             <filter-name> OpenSessionInView</filter-name >             <filter-class> org.springframework.orm.hibernate3.support.OpenSessionInViewFilter </filter-class>       </filter>       <filter-mapping>        <filter-name> OpenSessionInView</filter-name >        <url-pattern> /*</ url-pattern>    </filter-mapping >       <!-- struts2配置过滤器信息 -->      <filter >        <filter-name> struts2</filter-name >        <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter </filter-class>    </filter >    <filter-mapping >        <filter-name> struts2</filter-name >        <url-pattern> /*</ url-pattern>    </filter-mapping >    <!-- spring的配置监听器信息 -->    <context-param >             <param-name> contextConfigLocation</param-name >             <param-value> classpath:beans.xml</param-value >       </context-param>       <listener>             <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class>       </listener>    <welcome-file-list >    <welcome-file >index.jsp</ welcome-file>  </welcome-file-list ></web-app>

2.3配置spring配置文件（bean.xml）本次使用的是dbcp配置数据源，数据库为oracle,数据库地址为本地地址

<?xml version="1.0" encoding= "UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:aop="http://www.springframework.org/schema/aop"       xmlns:tx="http://www.springframework.org/schema/tx"       xmlns:context="http://www.springframework.org/schema/context"       xsi:schemaLocation="http://www.springframework.org/schema/beans                           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd                           http://www.springframework.org/schema/aop                           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd                           http://www.springframework.org/schema/context                           http://www.springframework.org/schema/context/spring-context-3.0.xsd                           http://www.springframework.org/schema/tx                           http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">      <!-- 开启spring bean组件扫面 -->      <context:component-scan base-package= "test"/>      <!-- 配置数据源 -->      <bean id="dateSource" class="org.apache.commons.dbcp.BasicDataSource" >            <!-- 数据库连接配置信息 -->            <property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />            <property name="url" value="jdbc:oracle:thin:@localhost:1521:orcl" />            <property name="username" value="test"/>            <property name="password" value="123456"/>            <!-- 数据源相关配置信息 -->            <property name="initialSize" value="10"/>            <property name="maxActive" value="8"/>            <property name="maxIdle" value="6"/>      </bean >      <!--              使用 hbm映射文件进行配置      org.springframework.orm.hibernate3.LocalSessionFactoryBean              使用注解进行映射配置      org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean       -->      <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean" >       <!-- 把配置好的数据源注入到SessionFactory -->       <property name="dataSource" ref="dateSource"/>       <!-- 配置hibernate相关配置信息 -->       <property name="hibernateProperties" >             <props>                   <prop key="hibernate.show_sql" >true</ prop>                   <prop key="hibernate.formate_sql" >true</ prop>                   <prop key="hibernate.hbm2ddl.auto" >update</ prop>                   <prop key="hibernate.dialect" >org.hibernate.dialect.Oracle10gDialect</prop >                   <!-- 指定使用哪种方式来管理当前线程创建session -->                   <prop key="hibernate.current_session_context_class" >thread</ prop>             </props>       </property>       <!-- 向SessionFactory注册映射关系 -->       <property name="packagesToScan" >             <list>                   <value> test</value >             </list>       </property>      </bean ></beans>        

2.4创建测试实体类和测试类，测试sessionFactory是否创建成功
//测试实体类

 package test;import javax.persistence.Column;import javax.persistence.Entity;import javax.persistence.GeneratedValue;import javax.persistence.GenerationType;import javax.persistence.Id;import javax.persistence.SequenceGenerator;import javax.persistence.Table;@Entity@Table(name = "TEST")public class TestPo {        private int id;        private String name;        @Id        @Column(name = "ID", unique = true, nullable = false, precision = 10, scale = 0)        @GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQ")        @SequenceGenerator(name="SEQ",allocationSize=1,initialValue=1, sequenceName="SEQ")        public int getId() {            return id;        }        public void setId(int id) {            this.id = id;        }        @Column(name="NAME")        public String getName() {            return name;        }        public void setName(String name) {            this.name = name;        }}

package test1;import static org.junit.Assert .*;import javax.annotation.Resource;import org.hibernate.Session;import org.hibernate.SessionFactory;import org.hibernate.Transaction;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;import test.TestPo;//测试类@RunWith(SpringJUnit4ClassRunner.class) //使用spring测试框架，不需要启动web项目，加上注解就可以直接进行测试@ContextConfiguration ("/beans.xml" )public class testC{       @Resource(name="sessionFactory" )       private SessionFactory sessionFactory ;       @Test       public void createSessionFactory() {            Session session = sessionFactory.getCurrentSession();            Transaction tx = session.beginTransaction();            TestPo user = new TestPo();            user.setId(1);            user.setName( "name1");            session.save(user);            tx.commit();      }}

创建sessionFactory就可以了，接下来会继续更新整合。。。
