SSH1环境搭建及示例

1.前期准备
  Eclipse 3.7.0(下载地址：http://www.eclipse.org/downloads/）
  Tomcat7.0(下载地址：http://tomcat.apache.org/download-70.cgi）
  MySql Server5.0(下载地址：http://dev.mysql.com/downloads/）
  struts-1.2.9(下载地址：http://struts.apache.org/download.cgi#struts221）
  spring-2.0(下载地址：http://sourceforge.net/projects/springframework/files/）
  hibernate-3.2.0(下载地址：http://sourceforge.net/projects/hibernate/files/）
 
2.创建Web工程
  创建Web工程后并建立几个包
  ssh.dan.web/ssh.dan.manager/ssh.dan.dao/ssh.dan.domain
 
3.配置Struts1
  引入Struts1的相关jar包拷贝到WEB-INF/lib目录下
     Struts_Home/lib/*.jar
 引入Struts1的配置文件
     在webapps文件夹中解压struts-blank.war，将其中的struts-config.xml拷贝到项目中（WEB-INF下）   
 
4.配置Spring
 引入Spring的相关jar包拷贝到WEB-INF/lib目录下
   SPRING_HOME/dist/spring.jar
   SPRING_HOME/lib/log4j/log4j-1.2.14.jar
   SPRING_HOME/lib/jakarta-commons/commons-logging.jar
   SPRING_HOME/ lib/junit/junit.jar
   SPRING_HOME/ lib/aspect/*.jar
  引入Spring的配置文件
   将spring_home/samples/jpetstore/war/WEB-INF下的applicationContext.xml拷贝到项目中（src下），为了对其他的框架进行配置，我们将其复制为四份，分别命名为applicationContext-common.xml, applicationContext-daos.xml，applicationContext-managers.xml, applicationContext-actions.xml
 
5.配置Hibernate
  引入Hibernate的相关jar包拷贝到WEB-INF/lib目录下
    Hibernate_Home/lib/*.jar
   Hibernate_Home/hibernate3.jar
  再将mysql驱动拷贝到WEB-INF/lib目录下
   Mysql_Home/src/lib/jdbc2_0-stdext.jar
  引入Hibernate的配置文件
   将Hibernate_Home/etc下的hibernate.cfg.xml拷贝到项目中（src下）
 
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
 
[java] view plaincopy
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
 
[java] view plaincopy
<?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 www.2cto.com
      hibernate.cfg.xml（配置数据库及映射文件）
[html] view plaincopy

    dao包
      UserDao.java
 
[java] view plaincopy
package ssh.dan.dao; 
 
import ssh.dan.domain.User; 
 
public interface UserDao { 
 
    /**

     */ 
    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）
 
[java] view plaincopy
package ssh.dan.dao; 
 
import org.springframework.orm.hibernate3.support.HibernateDaoSupport; 
 
import ssh.dan.domain.User;

        return (User)getHibernateTemplate().load(User.class, userName);              
    } 
 
}

    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; 
    }

    public void setPassWord(String passWord) { 
        this.passWord = passWord;
