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：

[html] view plaincopy

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：

[java] view plaincopy

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：

[html] view plaincopy

<?xml version="1.0" encoding="UTF-8"?>
<project name="SSH构建脚本" default="生成Hibernate配置文件" basedir=".">
<property name="src.dir" value="${basedir}/src"/>
<property name="build.dir" value="${basedir}/bin"/>
<property name="webapp.dir" value="${basedir}/WebContent"/>
<property name="xdoclet.home" value="D:/Application/xdoclet-1.2.3"/>
<path id="xdoclet.task.classpath">
<fileset dir="${xdoclet.home}/lib">
<include name="**/*.jar"/>
</fileset>
</path>
<taskdef
name="hibernatedoclet"
classname="xdoclet.modules.hibernate.HibernateDocletTask"
classpathref="xdoclet.task.classpath"
/>
<target name="生成Hibernate配置文件">
<hibernatedoclet destdir="src">
<fileset dir="${src.dir}/com/tgb/domain">
<include name="**/*.java"/>
</fileset>
<hibernatecfg
destinationFile="hibernate.cfg.xml"
dialect="org.hibernate.dialect.MySQLDialect"
driver="com.mysql.jdbc.Driver"
username="root"
password="1"
jdbcurl="jdbc:mysql://127.0.0.1/test_ssh"
showsql="true"
version="3.0"
hbm2ddl="update"
xmlencoding="utf-8"
/>
</hibernatedoclet>
</target>
<target name="生成hibernate映射文件">
<hibernatedoclet destdir="src">
<fileset dir="${src.dir}">
<include name="com/tgb/domain/*.java"/>
</fileset>
<hibernate version="3.0"/>
</hibernatedoclet>
</target>
</project>

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

[html] view plaincopy

<?xml version="1.0" encoding="gb2312"?>
<!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="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="show_sql">true</property>
<property name="use_outer_join">false</property>
<property name="connection.username">root</property>
<property name="connection.password">1</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://127.0.0.1/test_ssh</property>
<property name="hbm2ddl.auto">update</property>
<mapping resource="com/tgb/domain/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>

User.hbm.xml

[html] view plaincopy

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping
>
<class
name="com.tgb.domain.User"
table="t_user"
>
<id
name="id"
column="id"
type="int"
>
<generator class="native">
</generator>
</id>
<property
name="username"
type="java.lang.String"
update="true"
insert="true"
column="username"
/>
<property
name="password"
type="java.lang.String"
update="true"
insert="true"
column="password"
/>
</class>
</hibernate-mapping>

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

[java] view plaincopy

package com.tgb.dao;
import com.tgb.domain.User;
public interface UserDao {
public void addUser(User user);
public User findUserByName(String userName);
}

UserDaoImpl.java

[java] view plaincopy

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

[java] view plaincopy

package com.tgb.manager;
import com.tgb.domain.User;
public interface UserManager {
public void addUser(User user);
public User findUserByName(String userName);
}

UserManagerImpl.java

[java] view plaincopy

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

[java] view plaincopy

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

[java] view plaincopy

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。
