Web开发技术

Web Struts Spring Hibernate Bean

这个Web应用很简单，就是实现一个用户注册页面，当用户在register.jsp页面输入注册信息，点保存，如果成功，进入registerSuccess.jsp页面。这个应用虽然很小，但它也有三层组成，表示层由Struts框架负责，业务层由Spring框架负责，持久层由Hibernate框架负责。
开发环境：MyEclipse 5+ MySQL4 + Struts1.3.5 + Spring2.0.1 + Hibernate3.2.1 + Tomcat5.0.19 + jdk1.4.2_06.
1. 首先，我们在MyEclipse中新建一个Web Project ,login；
2．然后把Struts,Spring,Hibernate框架所需要的jar包以及MySQL的驱动拷贝到WEB－INF\lib下；
3．创建用户注册页面register.jsp

 1<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
 2<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
 3<html>
 4 
 5<head>
 6 <title><bean:message key="register.title"/></title>
 7</head>
 8 
 9<body>
10<html:errors />
11 <html:form action="register.do">
12    <table >
13      <tr>
14        <td><bean:message key="register.username"/>:</td>
15        <td><html:text property="register.username" /></td>
16      </tr>
17      <tr>
18        <td><bean:message key="register.password"/>:</td>
19        <td><html:password property="register.password" /></td>
20      </tr>
21       <tr>
22        <td><bean:message key="register.email"/>:</td>
23        <td><html:text property="register.email" /></td>
24      </tr>
25      <tr>
26        <td colspan="2" align="center">
27        <html:submit><bean:message key="register.submit"/></html:submit>
28        </td>
29      </tr>
30    </table>
31 </html:form>
32</body>
33 
34</html>

4.创建注册成功后显示的页面registerSuccess.jsp

 1<%@ taglib uri=" http://struts.apache.org/tags-bean " prefix="bean" %>
 2<html>
 3 
 4<head>
 5 <title><bean:message key="register.title"/></title>
 6</head>
 7 
 8<body>
 9 <bean:message key="register.success"/>
10</body>
11 
12</html>

5. 创建消息资源文件registermessages.properties

1register.title = Register
2register.username = UserName
3register.password = Password
4register.email = Email
5register.submit = Submit
6register.success = RegisterSuccess!

6. 由于我们使用动态ActionForm,只需在Struts-config.xml中配置与register.jsp页面中form对应的ActionForm。
7. 创建配置文件Struts-config.xml

1<?xml version="1.0" encoding="iso-8859-1"?>
 2<!DOCTYPE struts-config PUBLIC
 3        "-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
 4        "http://struts.apache.org/dtds/struts-config_1_3.dtd">
 5<!--
 6 Default configuration file for examples application.
 7 Each module also has its own struts-config under: /WEB-INF/$MODULE/
 8 @version $Revision: 1.9 $ $Date: 2006-02-13 18:39:49 -0700 (Mon, 13 Feb 2006) $
 9-->
10<struts-config>
11 <form-beans >
12   <!—配置register.jsp中form对应的ActionFrom-->
13    <form-bean name="registerForm" type="org.apache.struts.action.DynaActionForm" >
14        <form-property name="register" type="test.register.entity.Register"/>                     
15    </form-bean>
16 </form-beans>
17 <!—配置对Struts Action请求的代理-->
18 <controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>
19 <!—配置register.jsp中form对应的Action-->
20 <action-mappings >
21    <action      
22      name="registerForm"
23      path="/register"
24      scope="request"
25      type="test.register.action.RegisterAction"
26      validate="false"
27      input="register.jsp">
28      <forward name="success" path="/registerSuccess.jsp" />
29    </action>
30   </action-mappings>
31 
32 <message-resources parameter="test.register.registermessages" />
33 <!—配置插件，让action能访问sping容器-->
34 <plug-in
35       className="org.springframework.web.struts.ContextLoaderPlugIn">
36       <set-property property="contextConfigLocation"
37           value="/WEB-INF/action-servlets.xml" />
38</plug-in>
39 
40</struts-config>

8. 创建实体类Register.java

 1package test.register.entity;
 2 
 3import java.io.Serializable;
 4 
 5publicclass Register implements Serializable{   
 6    privatestaticfinallongserialVersionUID = 1521645755684977819L;
 7    private Long id;
 8    private String username;
 9    private String password;
10    private String email;
11    
12    public Register(){
13       
14    }
15 
16    public String getEmail() {
17       returnemail;
18    }
19 
20    publicvoid setEmail(String email) {
21       this.email = email;
22    }
23 
24    public Long getId() {
25       returnid;
26    }
27 
28    publicvoid setId(Long id) {
29       this.id = id;
30    }
31 
32    public String getPassword() {
33       returnpassword;
34    }
35 
36    publicvoid setPassword(String password) {
37       this.password = password;
38    }
39 
40    public String getUsername() {
41       returnusername;
42    }
43 
44    publicvoid setUsername(String username) {
45       this.username = username;
46    }
47    
48    
49 
50}

9.创建Hibernate映射文件，Register.hbm.xml

 1<?xml version="1.0"?>
 2<!DOCTYPE hibernate-mapping PUBLIC 
 3    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
 4    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
 5<hibernate-mapping 
 6    package="test.register.entity">
 7 
 8    <class name="Register" table="REGISTER">
 9       
10       <id name="id">
11           <generator class="native"/>
12       </id>
13              
14    <property name="username" 
15            not-null="true"
16            length="15"
17            column="USERNAME"/>
18       
19    <property name="password" 
20            not-null="true"
21            length="15"
22            column="PASSWORD"/>
23       
24    <property name="email"
25            not-null="true"
26            length="15"
27            column="EMAIL"/>       
28       
29    </class>
30    
31</hibernate-mapping>

10. 创建Spring配置文件applicationContext.xml

1<?xml version="1.0" encoding="UTF-8"?>
 2<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
 3 
 4<beans>    
 5 
 6    <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
 7<property name="driverClassName" value="com.mysql.jdbc.Driver"/>
 8       <property name="url" value="jdbc:mysql://localhost/register"/>
 9       <property name="username" value="root"/>
10       <property name="password" value="root"/>
11    </bean>    
12 
13    <!-- Hibernate SessionFactory -->
14    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
15       <property name="dataSource" ref="dataSource"/>
16       <property name="mappingDirectoryLocations">
17           <value>classpath:test\register\entity\</value>
18       </property>
19       <property name="hibernateProperties">
20           <props>
21              <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
22              <prop key="hibernate.show_sql">true</prop>
23              <prop key="hibernate.generate_statistics">true</prop>
24           </props>
25       </property>       
26    </bean>    
27    
28   <bean id="registerDAO" class="test.register.dao.RegisterDAO">
29        <property name="sessionFactory">
30             <ref local="sessionFactory"/>
31        </property>
32 </bean>
33 
34   <bean id="registerService" class="test.register.service.RegisterService">
35        <property name="registerDAO">
36             <ref local="registerDAO"/>
37        </property>
38 </bean>
39 
40</beans>

11. 创建数据访问对象RegisterDAO.java

1package test.register.dao;
 2 
 3import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
 4 
 5import test.register.entity.Register;
 6 
 7publicclass RegisterDAO extends HibernateDaoSupport{
 8    
 9    public Register saveRegister(Register r){
10       try{
11           this.getHibernateTemplate().saveOrUpdate(r);
12           return r;
13       }catch (Exception e) {
14           e.printStackTrace();
15           returnnull;
16       }      
17    }
18}

12.创建服务对象RegisterService.java

1package test.register.service;
 2 
 3import test.register.dao.RegisterDAO;
 4import test.register.entity.Register;
 5 
 6publicclass RegisterService {
 7    private RegisterDAO registerDAO;   
 8    
 9    publicRegisterDAO getRegisterDAO() {
10       returnregisterDAO;
11    }
12 
13    publicvoid setRegisterDAO(RegisterDAO registerDAO) {
14       this.registerDAO = registerDAO;
15    }
16 
17    public Register saveRegister(Register r){
18       this.getRegisterDAO().saveRegister(r);
19       return r;
20    }
21}

13. 创建web.xml

 1<?xml version="1.0" encoding="UTF-8"?>
 2<!DOCTYPE web-app PUBLIC
 3        "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 4        "http://java.sun.com/dtd/web-app_2_3.dtd">
 5<web-app>
 6<context-param>
 7    <param-name>contextConfigLocation</param-name>
 8    <param-value>/WEB-INF/applicationContext.xml</param-value>
 9</context-param>
10<listener>
11    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
12</listener>
13<servlet>
14    <servlet-name>action</servlet-name>
15    <servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
16    <init-param>
17      <param-name>config</param-name>
18      <param-value>/WEB-INF/struts-config.xml</param-value>
19    </init-param>
20    <init-param>
21      <param-name>debug</param-name>
22      <param-value>3</param-value>
23    </init-param>
24    <init-param>
25      <param-name>detail</param-name>
26      <param-value>3</param-value>
27    </init-param>
28    <load-on-startup>0</load-on-startup>
29 </servlet>
30 
31 <servlet-mapping>
32    <servlet-name>action</servlet-name>
33    <url-pattern>*.do</url-pattern>
34 </servlet-mapping>
35 
36 <welcome-file-list>
37  <welcome-file>register.jsp</welcome-file>
38 </welcome-file-list>
39 
40</web-app>

14．创建RegisterAction.java

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 org.apache.struts.action.DynaActionForm;
 
import test.register.entity.Register;
import test.register.service.RegisterService;
 
publicclass RegisterAction extends Action{
    
    private RegisterService registerService;
 
    public RegisterService getRegisterService() {
       returnregisterService;
    }
 
    publicvoid setRegisterService(RegisterService registerService) {
       this.registerService = registerService;
    }
 
    public ActionForward execute(ActionMapping mapping,
                                ActionForm form, 
                         HttpServletRequest request, 
                          HttpServletResponse response) 
    throws Exception {
 
       Register r = (Register)((DynaActionForm)form).get("register"); 
       getRegisterService().saveRegister(r);     
       return mapping.findForward("success");
    }
}

在RegisterAction.java中，为了获取spring容器中的RegisterService对象，我们要对struts-config.xml作下修改，具体修改如下：
在struts-config.xml增加controller元素

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>

目的告诉Struts自动将对Action的请求委托给Spring上下文中的Struts Action来处理。
并且为了让Struts能访问Spring容器，还必须在struts-config.xml注册一个能访问Spring上下文的插件：

<plug-in      className="org.springframework.web.struts.ContextLoaderPlugIn">
       <set-property property="contextConfigLocation"
           value="/WEB-INF/action-servlets.xml" />
</plug-in>

action-servlets.xml文件的具体内容如下：

1<?xml version="1.0" encoding="UTF-8"?>
2<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd">
3 
4<beans>    
5    <bean name="/register" class="test.register.action.RegisterAction">
6       <property name="registerService" ref="registerService"/>       
7    </bean>     
8</beans>

注意：这里bean是name属性，而不是id。
至此，一个完整的SSH（Struts,Spring,Hibernate）框架搭建好了。
