ssh整合1

本文描述的是框架SSH集成的示例，由於在這個過程中有一些小的細節容易被遺忘，特別撰寫了一篇小的博文來記錄這個過程，希望對自己以及後來者能夠起到積極意義。

本文中使用的框架和版本號爲：

struts-2.3.1.2、hibernate-3.6.10、spring-3.1.1

其下載地址分別爲：

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

分別將其解壓，需要注意的是本例中hibernate3還需要的是log4j，spring還需要commons-loging、commons-dbcp和commons-pool，在這裏就不再贅述出其下載地址了。

需要刪除的重複包爲：asm-commons-3.3.jar和javassist-3.11.0.GA.jar

需要使用的JAR包截圖：

接下來在jee中新建一個Dynamic Web Project，選擇好運行環境：

相關文件組織如下：

源代碼列舉如下：

UserAction.java

package com.ssh.action;import com.opensymphony.xwork2.ActionSupport;

this.service = service;
    }
public User getUser() {
return user;
    }
publicvoid setUser(User user) {
this.user = user;
    }

public String execute(){

    }
public User save(User user){
        Session session = factory.getCurrentSession();
        session.beginTransaction();
        session.save(user);
        session.getTransaction().commit();
return user;
    }
}

然後在Tomcat7上部署該項目即可，在瀏覽器中輸入地址：http://localhost:8080/ssh_demo/register即可進入下面的頁面：

至此，SSH框架整合完成。
