在做本例前，需要熟悉对
Struts，
Hibernate的反向工程等的基本操作。
开发工具：MyEclipse+MySQL+Tomcat
说明：本实例是简单注册程序（只有两个属性）
数据库脚本：user.sql
|
DROP TABLE IF EXISTS
`user`;
CREATE TABLE `user` (
`Id` int(11) NOT NULL
AUTO_INCREMENT,
`username` varchar(255) DEFAULT
NULL,
`password` varchar(255) DEFAULT
NULL,
PRIMARY KEY (`Id`)
) ENGINE=InnoDB AUTO_INCREMENT=3
DEFAULT CHARSET=utf8;
|
开发步骤：
一
1建立Web项目
选择：
Java EE 5.5
2添加Struts支持（项目右键àMyEclipse Struts Capabilities …）
选择：
1）Struts specification： Struts 1.3
2）Base package for 那位classes：edu.syict.struts
3添加Spring支持（项目右键àMyEclipse Spring Capabilities …）
选择：
1) Spring
version：Spring 2.0
2) Select the libraries to add the
buildpath：
Spring 2.0 AOP Libraries
Spring 2.0 Core
Libraries
Spring 2.0 Persistence Core
Libraries
Spring 2.0 Persistence JDBC
Libraries
Spring 2.0 Web Libraries
3) JAR Library Installation：
Copy checked Library contents to
project folder （TLDs always
copied）
Next
4) Spring配置文件选择目录Folder：WebRoot/WEB-INF
Finish
4 添加Hibernate支持（项目右键àMyEclipse Hibernate Capabilities …）
选择：
1）Hibernate
Specification：Hibernate3.1
2）Select the libraries to ad to
the buildpath：Hibernate 3.1
Core Libraries
3）JAR Library Installation：Copy checked Library Jars to project folder and
add to build-path
Next
4）选择：Spring configuration file(applicationContext.xml)
Next
5）选择：Existing Spring
configuration file
SessionFactory Id：
sessionFactory àNext
6）Bean Id：dataSource
DB Driver：选择配置好的Hibernate。àNext
7）不建立SessionFactory（不选择Create SessionFactory class?）
8）Finish。
二 数据库方面
1）建立包edu.syict.pojo
Hibernate反向工程：
选择下列内容：
Create
POJO<>DB Table mapping
information复选框
Create a Hibernate mapping file单选框
Update Hibernate configuration with mapping resource
location复选框
Java Data Object（POJO<>DB
Table）复选框
其余的都不选择。àNext
Id Generator：native àFinish
2）新建接口：edu.syict.dao.UserDao.java
(所在包：edu.syict.dao )
|
package edu.syict.dao;
import edu.syict.pojo.User;
public interface
UserDao {
public void save(User user);
}
|
3）建立UserDao接口实现类edu.syict.dao.impl.UserDaoImpl
类继承HibernateDaoSupport，接口继承UserDao
|
package edu.syict.dao;
import
org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import edu.syict.pojo.User;
public class
UserDaoImpl extends HibernateDaoSupport
implements UserDao {
public void save(User user) {
try{
this.getHibernateTemplate().saveOrUpdate(user);
}catch(RuntimeException re){
throw re;
}
}
}
|
三 建立JSP 页面，Action类
1) 打开struts-config.xml配置文件：右键new àForm,Action and JSP
2) User case：register
Form Impl：Dynamic
FormBean
Properties：username
password
JSP：选择Create JSP form
àNext
3) Action 默认就可以了
àFinish
4) 配置struts-config.xml文件，将Struts交给Spring管理
a) 加入插件 (message-resources标记下)
|
<plug-in
className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation"
value="/WEB-INF/applicationContext.xml"
/>
</plug-in>
|
b) 将Action类移交（message-resources标记上）
|
<controller
processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>
|
struts-config.xml文件(全部)
struts-config.xml文件(全部)
|
<?xml version="1.0"
encoding="UTF-8"?>
<!DOCTYPE struts-config PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 1.3//EN"
"http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>
<form-beans >
<form-bean name="registerForm"
type="org.apache.struts.action.DynaActionForm">
<form-property name="password"
type="java.lang.String" />
<form-property name="username"
type="java.lang.String" />
</form-bean>
</form-beans>
<global-exceptions
/>
<global-forwards
/>
<action-mappings
>
<action
attribute="registerForm"
input="/form/register.jsp"
name="registerForm"
path="/register"
scope="request"
type="edu.syict.struts.action.RegisterAction" />
</action-mappings>
<controller
processorClass="org.springframework.web.struts.DelegatingRequestProcessor"/>
<message-resources
parameter="edu.syict.struts.ApplicationResources"
/>
<plug-in
className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation"
value="/WEB-INF/applicationContext.xml"
/>
</plug-in>
</struts-config>
|
5) register.jsp页面(WebRoot/form/register.jsp)
|
<%@ page language="java"
pageEncoding="UTF-8"%>
<%@ taglib
uri="http://struts.apache.org/tags-bean"
prefix="bean"%>
<%@ taglib
uri="http://struts.apache.org/tags-html"
prefix="html"%>
<html>
<head>
<title>用户注册</title>
</head>
<body>
SSH整合<br><hr>
<h3>用户注册</h3>
<html:form action="/register">
用户名：<html:text
property="username"/><html:errors
property="username"/><br/>
密 码：<html:text
property="password"/><html:errors
property="password"/><br/>
<html:submit
value="注册"/> <html:reset
value="重置"/>
</html:form>
</body>
</html>
|
6）修改RegisterAction.java
|
package
edu.syict.struts.action;
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 edu.syict.dao.UserDao;
import edu.syict.pojo.User;
public class
RegisterAction extends Action {
//数据库Dao接口，并添加get方法，
private UserDao dao;
public void setDao(UserDao dao)
{
this.dao = dao;
}
public ActionForward execute(ActionMapping
mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
DynaActionForm registerForm = (DynaActionForm) form;
//在控制台输出
System.out.println(registerForm.get("username"));
System.out.println(registerForm.get("password"));
User user=new User();
user.setUsername((String) registerForm.get("username"));
user.setPassword((String) registerForm.get("password"));
dao.save(user);//向数据库中保存信息
return new
ActionForward("/form/register.jsp");
}
}
|
四 修改Spring配置文件applicationContext.xml
1）配置数据库UserDao
右键àSpringàNew Bean：
Bean Id：dao
Bean class：edu.syict.dao.UserDaoImpl
PropertiesàAdd：Name：sessionFactory
Reference：sessionFactory
Finish
2）配置Action（RegisterAction）
右键àSpringàNew Bean：
Name（与上不同，上位Id）：/register
Bean class：edu.syict.struts.action.RegisterAction
PropertiesàAdd：Name：userDao
Reference：dao
applicationContext.xml全部
|
<?xml version="1.0"
encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">

|
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property

<prop key="hibernate.dialect">

<property

</property>
</bean>
<bean id="dao"
class="edu.syict.dao.UserDaoImpl">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>
<!-- /register 与Action中的path相同
-->
<bean name="/register"
class="edu.syict.struts.action.RegisterAction">
<!-- RegisterAction中住的DAO的名称 -->
<property name="userDao">
<!-- 上面数据库Bean的id -->
<ref bean="dao" />
</property>
</bean>
</beans>
|
五 修改web .xml文件
添加Spring提供的过滤器，并修改欢迎页面（form/register.jsp）
web.xml
|
<!-- Spring提供的过滤器_Start -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/applicationContext.xml</param-value>
</context-param>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- Spring提供的过滤器_End
-->
<!-- 欢迎页面 -->
<welcome-file-list>
<welcome-file>form/register.jsp</welcome-file>
</welcome-file-list>
</web-app>
