SSH搭建

前言

本文以Tomcat为j2ee容器，数据库为Sqlserver2005进行说明。Struts版本为2.3.15.3,Spring版本为3.2.5,Hibernate版本为4.2.7

 

新建SSH

引入lib包

         所需包如下图所示：

web.xml配置

   <?xmlversion="1.0"encoding="UTF-8"?>

<web-appversion="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">

 

<!-- spring配置 -->

    <context-param>

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

        <param-value>/WEB-INF/applicationContext.xml/WEB-INF/spring-service.xml</param-value>

    </context-param>

 

    <listener>

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

    </listener>

   

    <!-- struts2配置 -->

    <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>

   

    <welcome-file-list>

        <welcome-file>index.jsp</welcome-file>

    </welcome-file-list>

</web-app>

 

新建applicationContext.xml

   在项目中WEB-INF下新建applicationContext.xml文件，注意此处JDBC配置使用的JNDI配置，大家可以根据具体情况进行更改，里面内容如下：

<?xmlversion="1.0"encoding="UTF-8"?>

<beansxmlns="http://www.springframework.org/schema/beans"

    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://www.springframework.org/schema/beans

          http://www.springframework.org/schema/beans/spring-beans.xsd"default-autowire="byName">

<!--配置service -->

    <beanid="managerService"class="org.ssh.service.ManagerService"/>

   

    <beanid="managerDao"class="org.ssh.dao.ManagerDao"/>

</beans>

 

新建struts.xml

在SRC目录下新建struts.xml文件，注意：要想实现Spring托管Struts必须在此配置文件中加入<constant name="struts.objectFactory"value="spring" />这句代码，具体内容如下：

<?xmlversion="1.0"encoding="UTF-8"?>

<!DOCTYPE strutsPUBLIC

    "-//ApacheSoftware Foundation//DTD Struts Configuration 2.0//EN"

    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>

    <constantname="struts.objectFactory"value="spring"/>

    <constantname="struts.devMode"value="false"/>

 

    <packagename="basicstruts2"extends="struts-default">

 

        <actionname="index">

            <result>/index.jsp</result>

        </action>

 

        <actionname="hello"

            class="org.apache.struts.helloworld.action.HelloWorldAction"method="execute">

            <resultname="success">/HelloWorld.jsp</result>

        </action>

 

    </package>

 

</struts>

 

 

新建hibernate.cfg.xml

         <?xmlversion='1.0'encoding='utf-8'?>

<!DOCTYPEhibernate-configuration PUBLIC

        "-//Hibernate/HibernateConfiguration DTD 3.0//EN"

        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

 

<hibernate-configuration>

 

    <session-factory>

 

        <!-- Database connection settings -->

        <!-- 普通连接

        <propertyname="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>

        <propertyname="connection.url">jdbc:sqlserver://localhost:1433;DatabaseName=ehr_db</property>

        <propertyname="connection.username">sa</property>

        <propertyname="connection.password">sa</property>

         -->

        <!-- JNDI连接 -->

        <propertyname="connection.datasource">java:comp/env/jdbc/ehrdb</property>

       

 

        <!-- JDBC connection pool (use thebuilt-in) -->

        <propertyname="connection.pool_size">1</property>

 

        <!-- SQL dialect -->

        <propertyname="dialect">org.hibernate.dialect.SQLServerDialect</property>

 

        <!-- Enable Hibernate's automatic sessioncontext management -->

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

 

        <!-- Disable the second-level cache  -->

        <propertyname="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

 

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

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

 

        <!-- Drop and re-create the databaseschema on startup -->

        <propertyname="hbm2ddl.auto">update</property>

 

        <mappingresource="org/ssh/model/TbManager.hbm.xml"/>

 

    </session-factory>

 

</hibernate-configuration>

 

新建HibernateUtil类

      package org.ssh.dao.util;

 

import org.hibernate.SessionFactory;

import org.hibernate.cfg.Configuration;

 

publicclass HibernateUtil {

 

    privatestaticfinal SessionFactory sessionFactory = buildSessionFactory();

 

    privatestatic SessionFactory buildSessionFactory(){

        try{

            // Create the SessionFactory fromhibernate.cfg.xml

            returnnew Configuration().configure().buildSessionFactory();

        }catch(Throwable ex){

            // Make sure you log the exception, as itmight be swallowed

            System.err.println("Initial SessionFactory creationfailed."+ ex);

            thrownew ExceptionInInitializerError(ex);

        }

    }

 

    publicstatic SessionFactory getSessionFactory(){

        return sessionFactory;

    }

 

}

     

部署运行

         将程序部署至tomcat，访问 http://localhost:8080/SSH 运行
