SSH框架整合示例

本文描述的是框架SSH集成的示例，由于在这个过程中有一些小的细节容易被遗忘，特别撰写了一篇小的博文来记录这个过程，希望对自己以及后来者能够起到积极意义。

本文中使用的框架和版本号为：

struts-2.3.1.2、hibernate-3.6.10、spring-3.1.1

其下载地址分别为：

http://struts.apache.org/download.cgi#struts2312

http://sourceforge.net/projects/hibernate/files/hibernate3/3.6.10.Final/

http://www.springsource.org/download/community?project=Spring%2520Framework&version=3.1.1.RELEASE

分别将其解压，需要注意的是本例中hibernate3还需要的是log4j，spring还需要commons-loging、commons-dbcp和commons-pool，在这里就不再赘述出其下载地址了。

需要删除的重复包为：asm-commons-3.3.jar和javassist-3.11.0.GA.jar

需要使用的JAR包截图：

接下来在jee中新建一个Dynamic Web Project，选择好运行环境：

 相关文件组织如下：

源代码列举如下：

UserAction.java

package com.ssh.action;import com.opensymphony.xwork2.ActionSupport;import com.ssh.pojo.User;import com.ssh.service.UserService;public class UserAction extends ActionSupport {private static final long serialVersionUID = 1L;private User user;private UserService service;public UserService getService() {return service;}public void setService(UserService service) {this.service = service;}public User getUser() {return user;}public void setUser(User user) {this.user = user;}public String execute(){if (service.save(user)!=null) {return SUCCESS;}else {return ERROR;}}}

User.java

 UserService.java

package com.ssh.service;import org.hibernate.Session;import org.hibernate.SessionFactory;import com.ssh.pojo.User;public class UserService {private SessionFactory factory = null;public SessionFactory getFactory() {return factory;}public void setFactory(SessionFactory factory) {this.factory = factory;}public User save(User user){Session session = factory.getCurrentSession();session.beginTransaction();session.save(user);session.getTransaction().commit();return user;}}

然后在Tomcat7上部署该项目即可，在浏览器中输入地址：http://localhost:8080/ssh_demo/register即可进入下面的页面：

至此，SSH框架整合完成。
