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;
}
}

新建数据库ssh_test，启动Tomcat后表就建立好了，然后开始运行，结果：
index界面：
user_add界面：
success界面：
数据库结果：
