SSH架构搭建-登录实例.ppt

SSH架构搭建-LoginDemo,By 黄圣彪,开发环境,Windows XP ProMyEclipse 5.5.1 GAMySQL 5.0,前期准备下载依赖包,/物流/SSH学习资料/lib,SSH架构开发步骤,环境配置添加SSH的依赖包编写SSH各层代码布署网站和测试,环境配置,建立MySQL数据库配置Tomcat服务器配置数据库的连接,环境配置-建立数据库,Enter Password:root,环境配置-建立数据库,Create database LoginDemo;use LoginDemo;CREATE TABLE user(id INTEGER NOT NULL auto_increment,userName VARCHAR(50),password VARCHAR(50),PRIMARY KEY(id)DEFAULT CHARSET=gbk;charset gbk;insert into user values(null,bill,123);,复制SQL脚本,环境配置-建立数据库,右键粘贴,回车,环境配置-配置Tomcat,Windows preferences,输入Tomcat,选择Tomcat 5.x,找到Tomcat的安装目录,环境配置-配置数据库连接,Windows Show View Other,工作区多了DB Browser,右键 new,环境配置-配置数据库连接,选择MySQL,找到刚下载的包:,User name:rootPassword:root,jdbc:mysql:/localhost:3306/LoginDemo,新建Web Project,LoginDemo,添加SSH的依赖包,添加顺序SpringHibernateStruts,添加依赖包-Spring,勾选5个库:AOPCoreORM/DAO/Hibernate3J2EEWeb,MyEclipse Add Spring Capabilities,添加依赖包-Spring,contextConfigLocation/WEB-INF/classes/applicationContext.xml SpringContextServlet 1,修改web.xml,增加以下内容:,添加依赖包-Hibernate,MyEclipse Add Hibernate Capabilities,添加依赖包-Hibernate,sessionFactory,添加依赖包-Hibernate,选择刚才配置的数据库连接勾选 Copy DB driver jars,添加依赖包-Hibernate,dataSource,添加依赖包-Hibernate,添加依赖包-Hibernate,删除冲突的3个包:asm.jarasm-attr.jar增加连接池管理包:,到目录 LoginDemoWebRootWEB-INFlib,添加依赖包-Struts,MyEclipse Add Struts Capabilities,编写SSH各层代码,各层职责:Hibernate:PO类,DAO接口,DAO实现Spring:Service接口,Service类,applicationContext.xmlStruts:Action,ActionForm,struts-config.xml,编写SSH各层代码,SSH层次调用说明图,SSH代码编写-Hibernate,DB Browser,右键Hibernate Re,右键Open Connetion,SSH代码编写-Hibernate,SSH代码编写-Hibernate,SSH代码编写-Hibernate,结果,SSH代码编写-Hibernate,编写DAO接口,SSH代码编写-Hibernate,DAO接口对数据库操作的接口,一般包含CRUD操作。,命名方式可根据习惯,SSH代码编写-Hibernate,New 一个dao包,将生成的IUserDAO移进去,SSH代码编写 单元测试,编写Juint单元测试,保证编写的DAO的正确性,SSH代码编写 Spring,Service接口提供业务处理对外接口,SSH代码编写 Spring,package;import;public interface UserService public User getUserByUserName(String userName);public void addUser(User user);,UserService.java,SSH代码编写 Spring,Service接口实现提供业务处理,package;import;import;import;import;public class UserServiceImpl implements UserService private UserDAO userDAO;public UserDAO getUserDAO()return userDAO;public void setUserDAO(UserDAO userDAO)this.userDAO=userDAO;public void addUser(User user)public User getUserByUserName(String userName)User user=null;List list=userDAO.findByUserName(userName);if(list.size()0)user=(User)list.get(0);return user;,SSH代码编写 Spring,UserServiceImpl.java,DAO接口成员,并生成get set方法,SSH代码编写 Spring,修改applicationContext.xml,SSH代码编写 单元测试,编写Juint单元测试,保证编写的Service的正确性,SSH代码编写 Struts,SSH代码编写 Struts,输入action,选择,SSH代码编写 Struts,SSH代码编写 Struts,SSH代码编写 Struts,public ActionForward execute(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response)LoginForm loginForm=(LoginForm)form;ActionForward forward=mapping.getInputForward();String userName=loginForm.getUserName();String password=loginForm.getPassword();UserService service=(UserService)getWebApplicationContext().getBean(UserService);User userFromDB=service.getUserByUserName(userName);if(userFromDB!=null)if(password.equals(userFromDB.getPassword()forward=mapping.findForward(success);elseforward=mapping.findForward(fail);return forward;,Action ActionSupport,如果有错误,可能是有些包没有导入按下快捷键 Ctrl+Shfit+O,导入包,SSH代码编写 Struts,struts-config.xml,SSH代码编写 界面,welcome.jsp,login.jsp,用户名：密 码：,登陆成功,布署网站和测试,布署网站和测试,布署网站和测试,布署网站和测试,打开IE,输入 http:/localhost:8080/LoginDemo/login.jsp,总结,文件结构图,Hibernate层,Spring层,Struts层,注意:将po包移进dao包更符合逻辑移动po包,要修改几个特定的地方这里暂时不讨论,有兴趣同学可以自己探索,
