  1. OOT实习指南 顾天晓 ktxjoro@gmail.com

  2. 内容提要 • 运行起Jpetstore • Jpetstore源码解析 • SpringIoC • Spring MVC • 实习项目分析

  3. 运行Jpetstore • 搭建环境 • 下载安装jdk • 下载安装SpringSourceTool Suite • 下载subversion插件 • 下载Jpetstore源码 • 编译、打包、部署

  4. 下载subversion插件 • Eclipse Plugin • http://www.eclipse.org/subversive/downloads.php • Help->Install New Software • Update site • http://download.eclipse.org/technology/subversive/0.7/update-site/ • SpringByExample

  5. 下载jpetstore源码 • SpringSource.org • https://src.springsource.org/svn/spring-samples/ • svn co https://src.springsource.org/svn/spring-samples/jpetstore/trunk/org.springframework.samples.jpetstore/jpetstore • Use subversion plugin • SpringByExample

  6. 编译、打包源码 • Maven • http://maven.apache.org/ • STS已经集成Maven插件 • Project Object Model • pom.xml • validate, compile, test, package, integration-test, verify, install, deploy

  7. 编译、打包源码 • pom.xml • <properties> • <dependencies> • <repositories> • <plugins>

  8. 编译、打包源码 • Jpetstore readme.txt • 1. Run "mvn package" to generate the WAR file • 2. Copy the generated "target/org.springframework.samples.jpetstore-1.0.0-SNAPSHOT.war" to “<TOMCAT_HOME>/webapps/jpetstore.war" • 3. Start HSQLDB via "db/hsqldb/server.bat" or "db/hsqldb/server.sh" • 4. Start Tomcat (default port will be 8080) • 5. Open "http://localhost:8080/jpetstore" in an Internet browser

  9. 编译、打包源码 • 修改pom.xml • <spring.version>3.0.4.RELEASE</spring.version> • 添加slf4j-nop-1.5.2.jar运行依赖支持 <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-nop</artifactId> <version>1.5.2</version> <scope>runtime</scope> </dependency>

  10. 编译、打包源码 • 启动数据库hsqldb • windows：server.bat • Linux：server.sh • Server.bat • mvn -f %~dp0pom.xml -Ddb.file=%~dp0jpetstore exec:java

  11. 编译、打包源码 • 拷贝target/目录下的war文件至tomcat下的webapps文件夹下 • 重命名为jpetstore • http://localhost:8080/jpetstore

  12. Spring 源码分析 • SpringSource Tool中演示

  13. Spring IoC • Inversion of Control • dependency injection • It is a process whereby objects define their dependencies, that is, the other objects they work with, only through constructorarguments, arguments to a factory method, or properties that are set on the object instance after it is constructed or returned from a factory method.

  14. Spring IoC • PetStore <bean id="petStore" class="org.springframework.samples.jpetstore.domain.logic.PetStoreImpl"> <property name="accountDao" ref="accountDao"/> <property name="categoryDao" ref="categoryDao"/> <property name="productDao" ref="productDao"/> <property name="itemDao" ref="itemDao"/> <property name="orderDao" ref="orderDao"/> </bean>

  15. Spring IoC • org.springframework.samples.jpetstore.domain.logic.PetStoreImpl public class PetStoreImpl implements PetStoreFacade, OrderService { private AccountDaoaccountDao; private CategoryDaocategoryDao; private ProductDaoproductDao; private ItemDaoitemDao; private OrderDaoorderDao; … }

  16. Jpetstore源码解析 • Java package • dao.* 数据层 • domain.* 逻辑层 • web.* 表现层

  17. Spring MVC • Model-View-Controller • The Spring Web model-view-controller (MVC) framework is designed around a DispatcherServlet that dispatches requests to handlers, with configurable handler mappings, view resolution, locale and theme resolution as well as support for uploading files.

  18. Spring MVC

  19. Spring MVC • Controller • Synchronize changes between model and view Action model view Controller

  20. Spring MVC • web.xml – entry-point for use spring in tomcat <servlet> <servlet-name>petstore</servlet-name> <servlet-class> org.springframework.web.servlet.DispatcherServlet </servlet-class> <load-on-startup>2</load-on-startup> </servlet> • Action –Views are modified by Actions and controllers receive the modification, then reflect it to model <servlet-mapping> <servlet-name>petstore</servlet-name> <!-- <servlet-name>action</servlet-name> --> <url-pattern>*.do</url-pattern> </servlet-mapping>

  21. Spring MVC • petstore-servlet.xmlmap action to controller <bean id="defaultHandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/> <bean name="/shop/addItemToCart.do" class="org.springframework.samples.jpetstore.web.spring.AddItemToCartController"> <property name="petStore" ref="petStore"/> </bean> • product.jsp action definition <td><a href="<c:url value="/shop/addItemToCart.do"><c:param name="workingItemId" value="${item.itemId}"/></c:url>"> <img border="0" src="../images/button_add_to_cart.gif"/> </a></td>

  22. 实习题目介绍 • 医院挂号系统 • 通过网页访问某医院的预约挂号系统（普通号、专家号、特需号），用户需实名注册，预约成功后得到预约号，在规定时间前不去医院实际挂号则取消预约号。 • 预约不成功则进入等待序列，当有空余号时，挂号系统将自动发送短信或EMAIL将预约号通知用户，用户确认后生效，预约成功。

  23. 医院挂号系统 • 用户系统 • 注册与登录 • 挂号系统 • 挂号成功 • 挂号失败 • ＥＭＡＩＬ通知
