SSH1环境搭建及示例(二)

6.编写代码

  基本框架建立好后,我们添加几个类,展示一下目录:

 

  下面是示例代码

   先建立数据库ssh_test,再编写实体类建表

   建立表时需要用到一些工具,我们建立一个工具包

   domain包

       User.java

 

package ssh.dan.domain;

public class User {
	
	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;
	}

}


      User.hbm.xml

 

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
	"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
	"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
	<class name="ssh.dan.domain.User" table="t_user">
		<id name="userName">
			<generator class="assigned"/>
		</id>
		<property name="passWord"/>
	</class>
</hibernate-mapping>


    配置文件

      hibernate.cfg.xml(配置数据库及映射文件)

<!DOCTYPE hibernate-configuration PUBLIC
	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
	"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>
	<session-factory>
		<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/ssh_test</property>
		<property name="hibernate.connection.username">root</property>
		<property name="hibernate.connection.password">dandan</property>
		<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
		<property name="hibernate.show_sql">true</property>
		<property name="hibernate.hbm2ddl.auto">update</property>
		
		<mapping resource="ssh/dan/domain/User.hbm.xml"/>
	</session-factory>
</hibernate-configuration>


 

    dao包

      UserDao.java

 

package ssh.dan.dao;

import ssh.dan.domain.User;

public interface UserDao {

	/**
	 * 添加用户
	 * @param user
	 */
	public void addUser(User user);	
	
	/**
	 * 根据用户名查找用户
	 * @param userName
	 * @return
	 */
	public User findUserByName(String userName);
	
}


      UserDaoImpl.java(使用了spring框架对Hibernate的集成的HibernateDaoSupport类)

 

package ssh.dan.dao;

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

import ssh.dan.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);				
	}

}


    manager包

      UserManager.java

package ssh.dan.manager;

import ssh.dan.domain.User;

public interface UserManager {

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


 

      UserManagerImpl.java(使用setter注入方式)

package ssh.dan.manager;

import ssh.dan.dao.UserDao;
import ssh.dan.domain.User;

public class UserManagerImpl implements UserManager {

	private UserDao userDao;
	
	@Override
	public void addUser(User user) {
		try{	
			if(findUserByName(user.getUserName()) != null){
				userDao.addUser(user);
			}
		}catch(Exception e){
			e.printStackTrace();
		}
	}
	
	@Override
	public User findUserByName(String userName) {
		User user = null;
		try{			
			user = userDao.findUserByName(userName);
		}catch(Exception e){
			e.printStackTrace();
		}
		return user;		
	}
	
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}	

}


 

    web包

      UserActionForm.java

 

package ssh.dan.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 ssh.dan.web;

import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
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 ssh.dan.domain.User;
import ssh.dan.manager.UserManager;



public class UserAction extends Action {
	
	private 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");
	}


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