Struts1+Hibernate+Spring整合实例(一)

      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MavenAnt也加入进来,如果SSHMavenAnt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:

Ant1.8.4

Xdoclet1.2.3;(个人喜欢1.0版本)

JDK1.6

Tomcat6

数据库:MySQL

首先新建一个web Projecttgb_ssh),右击项目选中Configure—Convert to Maven ProjectFinish!下面是pom.xml配置:

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:

Struts1+Hibernate+Spring整合实例(一)_第1张图片

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

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

<?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"/>

   	<!-- 定义构建路径 -->
   	<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

<?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">

<!-- Generated file - Do not edit! -->

<hibernate-configuration>

	<!-- a SessionFactory instance listed as /jndi/name -->
	<session-factory>

		<!-- properties -->
		<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 files -->
		<mapping resource="com/tgb/domain/User.hbm.xml"/>
	</session-factory>

</hibernate-configuration>

User.hbm.xml

<?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

package com.tgb.dao;
import com.tgb.domain.User;

public interface UserDao {

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

UserDaoImpl.java

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

package com.tgb.manager;

import com.tgb.domain.User;

public interface UserManager {

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

UserManagerImpl.java

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UserActionUserActionForm两个类,如下:

UserActionForm.java

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

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。
