ssh

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

package com.ssh.pojo;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name="user")
public class User {
	private Integer id;
	private String username;
	private String password;
	@Id
	@GeneratedValue
	@Column(name="hr_id")
	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
}

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。
