Struts+Spring+Hibernate,SSH整合实例

网上虽然有很多SSH整合的小例子,但很多程序都出现了不是这样,就是那样的错误。自己总结了一下,终于做出的Struts+Spring+Hibernate整合的小例子,也是最基础的SSH实例,虽然是小例子,但什么程序都是从基础的做起。如果你弄明白了这个小实例,相信你的SSH整合框架技术也会提高很多。 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>
