• Struts2+Spring+Hibernate(SSH)框架的搭建


    首先需要下载struts2 ,spring4,hibernate5  的资源包;

    struts2资源包下载路径:http://www.apache.org/
    spring资源包下载路径:http://projects.spring.io/spring-framework/
    hibernate资源包下载路径:http://hibernate.org/orm/downloads/

    在SSH框架的搭建步骤:

    第一步:在eclipse中创建一个web项目,并生成web.xml文件; 

    第二步:往lib目录导入jar包:


    1.struts2所需的jar包:

    struts2.3.30appsstruts2-blankWebContentWEB-INFlib(如图所示:)

    2.spring 所需的jar包:

    spring-framework-4.2.2.RELEASE-distspring-framework-4.2.2.RELEASElibs(如图所示:)

    3.hibernate所需的jar包:

    hibernate-release-5.2.2.Finallib equired(如图所示:)

    4.mysql数据库以及dbcp连接池所需的jar包:(如图所示:)

    第三步:在web.xml 文件中配置struts的过滤器 ,spring 的监听器;(代码如下:)

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
      <display-name>ssh</display-name>
      <welcome-file-list>
        <welcome-file>default.jsp</welcome-file>
      </welcome-file-list>
      <!--配置struts的过滤器  -->
      <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>
      
      <!--配置spring的监听器  -->
      <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>
    </web-app>

    第四步:在src目录下创建四个包,分别是action 控制层、dao 数据层、entity 实体层 ,  
    service 业务层;(如图所示:)

    第五步:struts.xml的配置:在src目录下创建struts.xml文件(代码如下:)

    <?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>
        
        <!-- 第1步:先定义一个包 -->
        <package name="mypck001" extends="struts-default">
                
            <action name="Index" class="myIndexAction" method="execute1">          
                <result name="success">/WEB-INF/jsp/index2.jsp</result>
                <result name="error">/WEB-INF/jsp/s_tag.jsp</result>
            </action>
        </package>
    </struts>

    第六步:spring的配置与hibernate的配置: 在src目录下创建applicationContext.xml文件:(代码如下:)

    <?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:p="http://www.springframework.org/schema/p"  
            xmlns:aop="http://www.springframework.org/schema/aop"   
            xmlns:context="http://www.springframework.org/schema/context"  
            xmlns:jee="http://www.springframework.org/schema/jee"  
            xmlns:tx="http://www.springframework.org/schema/tx"  
            xsi:schemaLocation="    
                http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd  
                http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd  
                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
                http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.2.xsd  
                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">
        <!-- 引入外部属性文件 -->
        <context:property-placeholder location="classpath:jdbc.properties"/>
            
        <!-- 所有需要类的实例都由spring去管理 -->
        <bean id="myIndexAction" class="ssh.action.IndexAction" scope="prototype">
            <!-- setIs(myIndexService) -->
            <property name="is" ref="myIndexService"/>

         <bean id="mySessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
            <!-- 注入连接池,包含了数据库用户名,密码等等信息 -->
            <property name="dataSource" ref="myDataSource"/>
            
            <!-- 配置Hibernate的其他的属性 -->
            <property name="hibernateProperties">
                <props>

                    <!-- 开机自动生成表 -->

                </props>
            </property>
            
            <property name="mappingResources">
                <list>
                    <value>ssh/entity/BookCard.hbm.xml</value>
                </list>
            </property>
