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
