Struts+Spring+Hibernate--SSH整合实例
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
DROPTABLEIFEXISTS`user`;
CREATETABLE`user`(
`Id`int(11)NOTNULLAUTO_INCREMENT,
`username`varchar(255)DEFAULTNULL,
`password`varchar(255)DEFAULTNULL,
PRIMARYKEY(`Id`)
)ENGINE=InnoDBAUTO_INCREMENT=3DEFAULTCHARSET=utf8;
开发步骤：
一
1建立Web项目
选择：JavaEE5.5
2添加Struts支持（项目右键àMyEclipseStrutsCapabilities…）
选择：
1）Strutsspecification：Struts1.3
2）Basepackagefor那位classes：edu.syict.struts
3添加Spring支持（项目右键àMyEclipseSpringCapabilities…）
选择：
1)Springversion：Spring2.0
2)Selectthelibrariestoaddthebuildpath：
Spring2.0AOPLibraries
Spring2.0CoreLibraries
Spring2.0PersistenceCoreLibraries
Spring2.0PersistenceJDBCLibraries
Spring2.0WebLibraries
3)JARLibraryInstallation：
CopycheckedLibrarycontentstoprojectfolder（TLDsalwayscopied）
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àMyEclipseHibernateCapabilities…）
选择：
1）HibernateSpecification：Hibernate3.1
2）Selectthelibrariestoadtothebuildpath：Hibernate3.1CoreLibraries
3）JARLibraryInstallation：CopycheckedLibraryJarstoprojectfolderandaddtobuild-path
Next
4）选择：Springconfigurationfile(applicationContext.xml)Next
5）选择：ExistingSpringconfigurationfile
SessionFactoryId：sessionFactoryàNext
6）BeanId：dataSource
DBDriver：选择配置好的Hibernate。àNext
7）不建立SessionFactory（不选择CreateSessionFactoryclass?）
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：
CreatePOJO<>DBTablemappinginformation复选框
CreateaHibernatemappingfile单选框
UpdateHibernateconfigurationwithmappingresourcelocation复选框
JavaDataObject（POJO<>DBTable）复选框
其余的都不选择。àNext
IdGenerator：nativeàFinish
2）新建接口：edu.syict.dao.UserDao.java(所在包：edu.syict.dao)
packageedu.syict.dao;
importedu.syict.pojo.User;
publicinterfaceUserDao{
publicvoidsave(Useruser);
}
3）建立UserDao接口实现类edu.syict.dao.impl.UserDaoImpl
类继承HibernateDaoSupport，接口继承UserDao
packageedu.syict.dao;
importorg.springframework.orm.hibernate3.support.HibernateDaoSupport;
importedu.syict.pojo.User;
publicclassUserDaoImplextendsHibernateDaoSupportimplementsUserDao{
publicvoidsave(Useruser){
try{
this.getHibernateTemplate().saveOrUpdate(user);
}catch(RuntimeExceptionre){
throwre;
}
}
}
三建立JSP页面，Action类
1)打开struts-config.xml配置文件：右键newàForm,ActionandJSP
2)Usercase：register
FormImpl：DynamicFormBean
Properties：usernamepassword
JSP：选择CreateJSPformàNext
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-inclassname="org.springframework.web.struts.ContextLoaderPlugIn">
<set-propertyproperty="contextConfigLocation"
value="/WEB-INF/applicationContext.xml"/>
</plug-in>
b)将Action类移交（message-resources标记上）
<controllerprocessorclass="org.springframework.web.struts.DelegatingRequestProcessor"/>
struts-config.xml文件(全部)
struts-config.xml文件(全部)
<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEstruts-configPUBLIC"-//ApacheSoftwareFoundation//DTDStrutsConfiguration1.3//EN""http://struts.apache.org/dtds/struts-config_1_3.dtd">
<struts-config>
<form-beans>
<form-beanname="registerForm"type="org.apache.struts.action.DynaActionForm">
<form-propertyname="password"type="java.lang.String"/>
<form-propertyname="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>
<controllerprocessorclass="org.springframework.web.struts.DelegatingRequestProcessor"/>
<message-resourcesparameter="edu.syict.struts.ApplicationResources"/>
<plug-inclassname="org.springframework.web.struts.ContextLoaderPlugIn">
<set-propertyproperty="contextConfigLocation"
value="/WEB-INF/applicationContext.xml"/>
</plug-in>
</struts-config>
5)register.jsp页面(WebRoot/form/register.jsp)
<%@pagelanguage="java"pageEncoding="UTF-8"%>
<%@tagliburi="http://struts.apache.org/tags-bean"prefix="bean"%>
<%@tagliburi="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:formaction="/register">
用户名：<html:textproperty="username"/><html:errorsproperty="username"/><br/>
密 码：<html:textproperty="password"/><html:errorsproperty="password"/><br/>
<html:submitvalue="注册"/> <html:resetvalue="重置"/>
</html:form>
</body>
</html>
6）修改RegisterAction.java
packageedu.syict.struts.action;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importorg.apache.struts.action.Action;
importorg.apache.struts.action.ActionForm;
importorg.apache.struts.action.ActionForward;
importorg.apache.struts.action.ActionMapping;
importorg.apache.struts.action.DynaActionForm;
importedu.syict.dao.UserDao;
importedu.syict.pojo.User;
publicclassRegisterActionextendsAction{
//数据库Dao接口，并添加get方法，
privateUserDaodao;
publicvoidsetDao(UserDaodao){
this.dao=dao;
}
publicActionForwardexecute(ActionMappingmapping,ActionFormform,
HttpServletRequestrequest,HttpServletResponseresponse){
DynaActionFormregisterForm=(DynaActionForm)form;
//在控制台输出
System.out.println(registerForm.get("username"));
System.out.println(registerForm.get("password"));
Useruser=newUser();
user.setUsername((String)registerForm.get("username"));
user.setPassword((String)registerForm.get("password"));
dao.save(user);//向数据库中保存信息
returnnewActionForward("/form/register.jsp");
}
}
四修改Spring配置文件applicationContext.xml
1）配置数据库UserDao
右键àSpringàNewBean：
BeanId：dao
Beanclass：edu.syict.dao.UserDaoImpl
PropertiesàAdd：Name：sessionFactory
Reference：sessionFactory
Finish
2）配置Action（RegisterAction）
右键àSpringàNewBean：
Name（与上不同，上位Id）：/register
Beanclass：edu.syict.struts.action.RegisterAction
PropertiesàAdd：Name：userDao
Reference：dao
applicationContext.xml全部
<?xmlversion="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/beanshttp://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
<beanid="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<propertyname="dataSource">
<refbean="dataSource"/>
</property>
<propertyname="hibernateProperties">
<props>
<propkey="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
</props>
</property>
<propertyname="mappingResources">
<list>
<value>edu/syict/pojo/User.hbm.xml</value></list>
</property>
</bean>
<beanid="dao"class="edu.syict.dao.UserDaoImpl">
<propertyname="sessionFactory">
<refbean="sessionFactory"/>
</property>
</bean>
<!--/register与Action中的path相同-->
<beanname="/register"
class="edu.syict.struts.action.RegisterAction">
<!--RegisterAction中住的DAO的名称-->
<propertyname="userDao">
<!--上面数据库Bean的id-->
<refbean="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>
