SSH1环境搭建及示例

发布时间：2014-09-05 16:27:40作者：知识屋

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.zhishiwu.com
      hibernate.cfg.xml（配置数据库及映射文件）
[html] view plaincopy
<!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

[java] view plaincopy
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）

[java] view plaincopy
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
[java] view plaincopy
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）
[java] view plaincopy
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

[java] view plaincopy
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

[java] view plaincopy
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;
    }
}
