Struts1+Hibernate+Spring整合实例（一）

      SSH博文写的也差不多了，这篇主要是通过做一个完整简单的小例子，来整合下前面学到的东西，顺便把后面写的两篇Maven和Ant也加入进来，如果SSH或Maven、Ant这些东西不懂，可先看其他文章。项目用Maven来管理jar，我后面会把pom.xml贴出来，供大家参考，Maven之外的有：

Ant：1.8.4；

Xdoclet：1.2.3；（个人喜欢1.0版本）

JDK：1.6；

Tomcat：6；

数据库：MySQL；

首先新建一个web Project（tgb_ssh），右击项目选中Configure—Convert to Maven Project，Finish！下面是pom.xml配置：

  4.0.0
  tgb_ssh
  tgb_ssh
  1.0-SNAPSHOT
  war
  
    src
    
      
        maven-compiler-plugin

          1.6
        
      
      
        maven-war-plugin
        2.3
        
          WebContent
          false

下面是我整个项目包结构的一张截图，后面提及的类及配置文件请对号入座：

自底而上，先创建数据库：test_ssh，在domain包下创建一个实体类User.java：

package com.tgb.domain;

/**
 * 用户实体类
 * @author yuanfubiao
 *@hibernate.class table="t_user"
 *
 */
public class User {

	private int id;
	
	private String username;
	
	private String password;
	
	/**
	 * @hibernate.id generator-class="native"
	 */	
	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	/**
	 * @hibernate.property
	 */	
	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	/**
	 * @hibernate.property
	 */	
	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}	
}

然后创建build.xml，配置好后就可以生成Hibernate的配置文件和映射文件了，build.xml：

上面利用Ant+Xdoclet生成方式不多做介绍，可参看我后面的博客，生成的映射文件和配置文件如下：

hibernate.cfg.xml

	
	

		
		org.hibernate.dialect.MySQLDialect
		true
		false
		root
		1
		com.mysql.jdbc.Driver
		jdbc:mysql://127.0.0.1/test_ssh
		update
		
		
		
	

User.hbm.xml

完成domain层之后，在dao包下分别创建一个接口UserDao.java和实现类UserDaoImpl.java，如下：

UserDao.java

package com.tgb.dao;
import com.tgb.domain.User;

public interface UserDao {

	public void addUser(User user);
	
	public User findUserByName(String userName);
}

UserDaoImpl.java

package com.tgb.dao;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.tgb.domain.User;

public class UserDaoImpl extends HibernateDaoSupport implements UserDao{

	@Override
	public void addUser(User user) {
		getHibernateTemplate().save(user);
	}

	@Override
	public User findUserByName(String userName) {
		return (User)getHibernateTemplate().load(User.class, userName);
	}

}

接下来创建manager包下的接口UserManager.java和实现类UserManagerImpl.java，如下：

UserManager.java

package com.tgb.manager;

import com.tgb.domain.User;

public interface UserManager {

	public void addUser(User user);
	
	public User findUserByName(String userName);
}

UserManagerImpl.java

package com.tgb.manager;

import com.tgb.dao.UserDao;
import com.tgb.domain.User;

public class UserManagerImpl implements UserManager {

	private UserDao userDao;
	
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

	@Override
	public void addUser(User user) {
		userDao.addUser(user);
	}

	@Override
	public User findUserByName(String userName) {
		
		return userDao.findUserByName(userName);
	}

}

Web包下分别创建UserAction和UserActionForm两个类，如下：

UserActionForm.java

package com.tgb.web;

import org.apache.struts.action.ActionForm;

public class UserActionForm extends ActionForm {

	private String userName;
	
	private String password;

	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;
	}
	
}

UserAction.java

package com.tgb.web;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

import com.tgb.domain.User;
import com.tgb.manager.UserManager;

public class UserAction extends Action {

	private UserManager userManager;
	
	public void setUserManager(UserManager userManager) {
		this.userManager = userManager;
	}

	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		
		UserActionForm uaf = (UserActionForm)form;
		User user = new User();
		user.setUsername(uaf.getUserName());
		user.setPassword(uaf.getPassword());
		
		userManager.addUser(user);
		
		return mapping.findForward("success");
	}

}

Java类到此为止，这篇有点多，下篇文章继续。
