spring hibernate struts整合开发实例-oop

一，数据表（因为是一个小例子，所以只有一个表，毕竟这不是一个讲怎么配置hibernate级联的例子。）
CREATE TABLE `members` (
`id` int(7) NOT NULL auto_increment,
`name` varchar(20) NOT NULL default '',
`password` varchar(20) default NULL,
`sex` varchar(10) default NULL,
`mail` varchar(50) default NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `name` (`name`)
) ENGINE=MyISAM AUTO_INCREMENT=4 DEFAULT CHARSET=utf8
二，hibernate持久化类及映射文件、数据库操作封装DAO
package com.yang.product.booksonline.dao;

/**
* Members
*/

public class Members implements java.io.Serializable {

// Fields

private Integer id;
private String name;
private String password;
private String sex;
private String mail;

// Constructors

/** default constructor */
public Members() {
}

/** minimal constructor */
public Members(String name) {
this.name = name;
}

/** full constructor */
public Members(String name, String password, String sex, String mail) {
this.name = name;
this.password = password;
this.sex = sex;
this.mail = mail;
}

// Property accessors

public Integer getId() {
return this.id;
}

public void setId(Integer id) {
this.id = id;
}

public String getName() {
return this.name;
}

public void setName(String name) {
this.name = name;
}

public String getPassword() {
return this.password;
}

public void setPassword(String password) {
this.password = password;
}

public String getSex() {
return this.sex;
}

public void setSex(String sex) {
this.sex = sex;
}

public String getMail() {
return this.mail;
}

public void setMail(String mail) {
this.mail = mail;
}
}

三，spring配置

com.mysql.jdbc.Driver

jdbc:mysql://localhost:3306/books

root

snrdcqmq

org.hibernate.dialect.MySQLDialect

com/yang/product/booksonline/dao/Members.hbm.xml

四，struts配置及action类

attribute="membersForm"
name="membersForm"
parameter="action"
path="/members"
scope="request"
type="org.springframework.web.struts.DelegatingActionProxy" >

package com.yang.product.booksonline.action;

import java.util.List;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.DynaActionForm;
import org.apache.struts.actions.DispatchAction;

import com.yang.product.booksonline.dao.Members;
import com.yang.product.booksonline.dao.MembersDAO;

/**
* XDoclet definition:
* @struts.action path="/members" name="membersForm" parameter="action" scope="request" validate="true"
*/
public class MembersAction extends DispatchAction {
private MembersDAO membersDAO;

public MembersDAO getMembersDAO() {
return membersDAO;
}

public void setMembersDAO(MembersDAO membersDAO) {
this.membersDAO = membersDAO;
}

public ActionForward login (ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) {
// String url = request.getParameter("url");
String name = (String)((DynaActionForm)form).get("name");
String password = (String)((DynaActionForm)form).get("password");
List members = membersDAO.findByMembersName(name);
if (members != null && members.size() >0) {
Members member = (Members)members.get(0);
if (password.equals(member.getPassword())) {
request.getSession().setAttribute("member",name);
//return new ActionForward(url);
return mapping.findForward("loginSuccess");
} else {
return null;
}
} else {
return null;
}
}

public ActionForward logout (ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) {
request.getSession().removeAttribute("member");
return mapping.findForward("logoutSuccess");
}

public ActionForward register (ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) {
String name = (String)((DynaActionForm)form).get("name");
String password = (String)((DynaActionForm)form).get("password");
String sex = (String)((DynaActionForm)form).get("sex");
String mail = (String)((DynaActionForm)form).get("mail");
List members = membersDAO.findByMembersName(name);
if (members != null && members.size() >0) {
return null;
} else {
Members member = new Members();
member.setName(name);
member.setPassword(password);
member.setSex(sex);
member.setMail(mail);
membersDAO.save(member);
return mapping.findForward("registerSuccess");
}
}
}

注意到，这里使用了dispatchaction。
五，三个jsp部分内容
