在上篇文章中，我们已经把struts2+hibernate3.2+spring2.0的开发环境搭建成功，这篇我们接着上篇，继续讲解struts2+hibernate3.2+spring2.0的整合过程。
步骤二：在MySQL数据库中创建数据库、数据表，建表语句：
create database mytest; use mytest; CREATE TABLE users ( id int(11) NOT NULL, firstname varchar(50) NOT NULL, lastname varchar(50) NOT NULL, age int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;在此我们需要说明各层之间的调用关系，action层-->service层-->dao层，调用关系我们在spring中配置。
步骤三：建立hibernate对数据表的持久层访问。
在com.tgb.bean包中建立User.java和User.hbm.xml文件，用于建立和数据表users的映射。
User.java
package com.tgb.bean;
public class User {
private Integer id;
private String firstname;
private String lastname;
private int age;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getFirstname() {
return firstname;
}
public void setFirstname(String firstname) {
this.firstname = firstname;
}
public String getLastname() {
return lastname;
}
public void setLastname(String lastname) {
this.lastname = lastname;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
}
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="com.tgb.bean.User" table="users"> <id name="id" type="java.lang.Integer" column="id"> <generator class="increment"></generator> </id> <property name="firstname" type="string" column="firstname" length="50"></property> <property name="lastname" type="string" column="lastname" length="50"></property> <property name="age" type="java.lang.Integer" column="age"></property> </class> </hibernate-mapping>步骤四：创建操作User对象的接口和实现类。
在com.tgb.dao中创建操作User对象的接口
UserDAO.java
package com.tgb.dao;
import java.util.List;
import com.tgb.bean.User;
public interface UserDAO {
public void saveUser(User user);
public void removeUser(User user);
public User findUserById(Integer id);
public List<User> findAllUsers();
public void updateUser(User user);
} 在com.tgb.dao.impl中创建操作User对象的接口实现类
UserDAOImpl.java
package com.tgb.dao.impl;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.tgb.bean.User;
import com.tgb.dao.UserDAO;
public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {
@SuppressWarnings("unchecked")
public List<User> findAllUsers() {
String hql = "from User user order by user.id desc";
return (List<User>) this.getHibernateTemplate().find(hql);
}
public User findUserById(Integer id) {
User user = (User) this.getHibernateTemplate().get(User.class, id);
return user;
}
public void removeUser(User user) {
this.getHibernateTemplate().delete(user);
}
public void saveUser(User user) {
this.getHibernateTemplate().save(user);
}
public void updateUser(User user) {
this.getHibernateTemplate().update(user);
}
}
步骤五：创建service层的接口和实现类
在com.tgb.service中创建调用UserDAO的接口
UserService.java
package com.tgb.service;
import java.util.List;
import com.tgb.bean.User;
public interface UserService {
public List<User> findAll();
public void save(User user);
public void delete(User user);
public User findUserById(Integer id);
public void update(User user);
} 在com.tgb.service.impl中创建调用UserDAO的接口实现类
UserServiceImpl.java
package com.tgb.service.impl;
import java.util.List;
import com.tgb.bean.User;
import com.tgb.dao.UserDAO;
import com.tgb.service.UserService;
public class UserServiceImpl implements UserService {
private UserDAO userDao;
public UserDAO getUserDao() {
return userDao;
}
public void setUserDao(UserDAO userDao) {
this.userDao = userDao;
}
public void delete(User user) {
this.userDao.removeUser(user);
}
public List<User> findAll() {
return this.userDao.findAllUsers();
}
public User findUserById(Integer id) {
return this.findUserById(id);
}
public void save(User user) {
this.userDao.saveUser(user);
}
public void update(User user) {
this.userDao.updateUser(user);
}
}
步骤六：创建action层的对于SavaUser和ListUser的处理类。
SaveUserAction.java
package com.tgb.action.user;
import com.opensymphony.xwork2.ActionSupport;
import com.tgb.bean.User;
import com.tgb.service.UserService;
public class SaveUserAction extends ActionSupport {
private User user;
private UserService userService;
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
@Override
public String execute() throws Exception {
this.userService.save(this.user);
return SUCCESS;
}
} ListUserAction.java
package com.tgb.action.user;
import java.util.Map;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.tgb.service.UserService;
public class ListUserAction extends ActionSupport {
private UserService userService;
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
@Override
public String execute() throws Exception {
Map request = (Map) ActionContext.getContext().get("request");
request.put("list", userService.findAll());
return SUCCESS;
}
}
步骤七：创建用于保存用户的save.jsp页面和显示用户的list.jsp页面。
save.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>Save User</title>
</head>
<body>
<h1>
<font color="red">Operation List</font>
</h1>
<s:form action="saveUser">
<s:textfield name="user.firstname" label="%{getText('firstname')}"></s:textfield>
<s:textfield name="user.lastname" label="%{getText('lastname')}"></s:textfield>
<s:textfield name="user.age" label="age"></s:textfield>
<s:submit></s:submit>
</s:form>
</body>
</html>
list.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>List User</title>
</head>
<body>
<h1>
<font color="red"><center>
Users List
</center> </font>
</h1>
<table>
<tr>
<td>序号</td>
<td>姓</td>
<td>名</td>
<td>年龄</td>
<td>删除</td>
<td>更新</td>
</tr>
<s:iterator value="#request.list" id="us">
<tr>
<td>
<s:property value="#us.id" />
</td>
<td>
<s:property value="#us.firstname" />
</td>
<td>
<s:property value="#us.lastname" />
</td>
<td>
<s:property value="#us.age" />
</td>
<td>
<s:a href="deleteUser.action?user.id=%{#us.id}">delete</s:a>
</td>
<td>
<s:a href="updatePUser.action?user.id=%{#us.id}">update</s:a>
</td>
</tr>
</s:iterator>
</table>
</body>
</html>
到此，各层之间的接口和实现类已经创建完毕，下篇我们将讲解如何通过spring管理类之间的依赖关系。
