1. 下载spring包,网址如下:

  http://www.springframework.org/download.html

  解压后的目录中包含了dist、lib等子目录

  2. 在JBuilder2005中增加spring库,选择菜单Tools-Configure-Libraries,在弹出的对话框中点击New按钮,输入spring库的名称:spring,点击Add按钮,将dist目录中的所有jar文件增加到spring库中

  3. 新建工程文件,选菜单File-New Project,给工程文件取名为myProject

  设置工程文件的属性,选菜单Project-Project Properties,选择Tomcat作为服务器,将spring库加入Path/Required Libraries。因为例子中用到了log4j,将包含了log4j的库加入Path/Required Libraries,注意到lib目录下有两个子目录log4j和jakarta-commons,它们的用法是不同的,如下面的代码片断所示:

  log4j

  import org.apache.log4j.Level;
  import org.apache.log4j.Logger;

  public class SpringappController implements Controller {
  /** Logger for this class and subclasses */

  static Logger logger = Logger.getLogger(SpringappController.class);
  jakarta-commons
  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;
  public class SpringappController implements Controller {
  /** Logger for this class and subclasses */
  protected final Log logger = LogFactory.getLog(getClass());

  4. 新建Web模块,选菜单File-New,给Web模块取名为springapp

  5. 新建hello.jsp文件如下:

  <%@ page contentType="text/html; charset=Big5" %>
  <html>
  <head><title>Example :: Spring Application</title></head>
  <body>
  <h1>Hello - Spring Application</h1>
  <p>Greetings.</p>
  </body>
  </html>

  6. 新建类文件SpringappController.java如下:

  package spring;

  import org.springframework.web.servlet.mvc.Controller;
  import org.springframework.web.servlet.ModelAndView;
  import javax.servlet.ServletException;
  import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse;
  import java.io.IOException;

  //import org.apache.commons.logging.Log;
  //import org.apache.commons.logging.LogFactory;

  import org.apache.log4j.Level;
  import org.apache.log4j.Logger;

  public class SpringappController implements Controller {
  /** Logger for this class and subclasses */
  // protected final Log logger = LogFactory.getLog(getClass());

  static Logger logger = Logger.getLogger(SpringappController.class);
  public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {
  logger.info("SpringappController - returning hello view");
  return new ModelAndView("hello.jsp");
  }
  }

  7. 修改web.xml文件

  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE web-app PUBLIC '-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN' 'http://java.sun.com/dtd/web-app_2_3.dtd'>

  <web-app>

  <servlet>
  <servlet-name>springapp</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
  <servlet-name>springapp</servlet-name>
  <url-pattern>*.htm</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
  <welcome-file>
   index.jsp
  </welcome-file>
  </welcome-file-list>

  </web-app>

  8. 在web-inf目录中新建springapp-servlet.xml文件如下

  <?xml version="1.0" encoding="UTF-8"?>

  <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">


  <!-- - Application context definition for "springapp" DispatcherServlet. -->

  <beans>
  <bean id="springappController" class="spring.SpringappController"/>
  <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
  <props>
   <prop key="/hello.htm">springappController</prop>
  </props>
  </property>
  </bean>

  </beans>

  9. 在web-inf目录中新建log4j.properties文件如下:

  log4j.rootCategory=INFO, stdout, logfile

  log4j.appender.stdout=org.apache.log4j.ConsoleAppender

  log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

  log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n

  log4j.appender.logfile=org.apache.log4j.RollingFileAppender

  log4j.appender.logfile.File=springapp.log

  log4j.appender.logfile.MaxFileSize=512KB

  # Keep three backup files

  log4j.appender.logfile.MaxBackupIndex=3

  log4j.appender.logfile.layout=org.apache.log4j.PatternLayout

  #Pattern to output : date priority [category] - <message>line_separator

  log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - <%m>%n

   10. 设置web模块springapp的属性Content,加入文件log4j.properties,因为classes目录是自动产生的,这一步是为了把文件log4j.properties加到classes目录。

  11. 设置Run Configuration,选菜单Run-Configurations,新建一个Run Configuration,Type选Server,Launch URI设置为:/springapp/hello.htm,给它取名为hello

  12. 运行,你会在messages窗口中看到如下信息:

  資訊: Server startup in 9253 ms

  2004-11-05 15:05:00,585 INFO [spring.SpringappController] - <SpringappController - returning hello view>

  2004/11/5 下午 03:05:00 org.springframework.web.servlet.view.AbstractCachingViewResolver resolveViewName

  資訊: Cached view 'hello.jsp'

  在myProject/Tomcat/springapp.log文件中增加了一行如下所示:

  2004-11-05 15:11:32,348 INFO [spring.SpringappController] - <SpringappController - returning hello view>

  这说明你已成功建立了基本的spring应用。

  jstl的支持,设置工程文件的属性,选菜单Project-Project Properties,将jstl库加入Path/Required Libraries。

  14. 改进前面的例子,改进的文件如下:

  增加“header”文件include.jsp,这是一些jsp文件的公用部分,这样可以使得开发和维护更容易。所有jsp文件放在web-inf/jsp目录下,为的是只有Controller可以访问View。

  springapp/war/WEB-INF/jsp/include.jsp


  <%@ page session="false"%>

  <%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
  <%@ taglib prefix="fmt" uri="http://java.sun.com/jstl/fmt" %>


  利用JSTL,<c:redirect>将页面重定向到Controller,这样就建立了index.jsp和应用架构的联系。

  springapp/war/index.jsp


  <%@ include file="/WEB-INF/jsp/include.jsp" %>

  <%-- Redirected because we can't set the welcome page to a virtual URL. --%>
  <c:redirect url="/hello.htm"/>


  利用JSTL的<c:out>标记,把从Model提取的,传递给View的当前日期和时间作为输出。

  springapp/war/WEB-INF/jsp/hello.jsp


  <%@ include file="/WEB-INF/jsp/include.jsp" %>

  <html>
  <head><title>Hello :: Spring Application</title></head>
  <body>
  <h1>Hello - Spring Application</h1>
  <p>Greetings, it is now <c:out value="${now}"/>
  </p>
  </body>
  </html>


  在SpringappController.java中增加包含了当前日期和时间的string作为Model

  springapp/src/SpringappController.java


  import org.springframework.web.servlet.mvc.Controller;
  import org.springframework.web.servlet.ModelAndView;

  import javax.servlet.ServletException;
  import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse;

  import java.io.IOException;

  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;

  public class SpringappController implements Controller {

  /** Logger for this class and subclasses */
  protected final Log logger = LogFactory.getLog(getClass());

  public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {

  String now = (new java.util.Date()).toString();
  logger.info("returning hello view with " + now);

  return new ModelAndView("WEB-INF/jsp/hello.jsp", "now", now);
  }
  }


  15. 浏览改进后的结果http://localhost:8080/springapp,首先访问index.jsp,然后重定向到hello.htm,接著把控制交给Controller,Controller把日期和时间传送给View。

  只能在浏览器这样测试。在JBuilder2005中设置Run Configuration不能访问http://localhost:8080/springapp,但可以访问http://localhost:8080/springapp/index.jsp

  在上面的例子中,Controller指定了View的完全路径,使得Controller和View之间存在不必要的依赖。为了移出这种依赖,我们可以用类ResourceBundleViewResolver 和 a SimpleUrlHandlerMapping在属性文件中定义这种依赖,对于简单的情形,我们也可以利用InternalResourceViewResolver设置前缀和后缀,下面就用第二种方法。修改文件springapp-servlet.xml包含ViewResolver设置,我们还选择使用JstlView,这使得我们可以结合使用JSTL和message resource bundles,因此可以支持国际化。

  springapp/war/WEB-INF/springapp-servlet.xml


  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

  <!--
  - Application context definition for "springapp" DispatcherServlet.
  -->

  <beans>
  <bean id="springappController" class="SpringappController"/>

  <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
  <props>
   <prop key="/hello.htm">springappController</prop>
  </props>
  </property>
  </bean>

  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="viewClass"><value>org.springframework.web.servlet.view.JstlView</value></property>
  <property name="prefix"><value>/WEB-INF/jsp/</value></property>
  <property name="suffix"><value>.jsp</value></property>
  </bean>
  </beans>


  现在,我们就可以移出Controller中View名称的前缀和后缀了。


  springapp/src/SpringappController.java

  import org.springframework.web.servlet.mvc.Controller;
  import org.springframework.web.servlet.ModelAndView;

  import javax.servlet.ServletException;
  import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse;

  import java.io.IOException;

  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;

  public class SpringappController implements Controller {

  /** Logger for this class and subclasses */
  protected final Log logger = LogFactory.getLog(getClass());
  
  public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {

  String now = (new java.util.Date()).toString();
  logger.info("returning hello view with " + now);

  return new ModelAndView("hello", "now", now);
  }
  }


  这样修改后的例子应该仍能运行。
   16. 增加商业逻辑类

  为了分开Web逻辑和商业逻辑,我们建立两个不同的包,web和bus

  springapp/src/bus/Product.java

  package bus;

  import java.io.Serializable;

  public class Product implements Serializable {

  private String description;
  private Double price;

  public void setDescription(String s) {
  description = s;
  }

  public String getDescription() {
  return description;
  }

  public void setPrice(Double d) {
  price = d;
  }

  public Double getPrice() {
  return price;
  }

  }

  springapp/src/bus/ProductManager.java

  package bus;

  import java.io.Serializable;
  import java.util.List;

  public class ProductManager implements Serializable {

  private List products;
  public void setProducts(List p) {
  products = p;
  }

  public List getProducts() {
  return products;
  }

  }

  修改SpringappController.java

  springapp/src/web/SpringappController.java

  package web;

  import org.springframework.web.servlet.mvc.Controller;
  import org.springframework.web.servlet.ModelAndView;

  import javax.servlet.ServletException;
  import javax.servlet.http.HttpServletRequest;
  import javax.servlet.http.HttpServletResponse;

  import java.io.IOException;
  import java.util.Map;
  import java.util.HashMap;

  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;

  import bus.Product;
  import bus.ProductManager;

  public class SpringappController implements Controller {

  /** Logger for this class and subclasses */
  protected final Log logger = LogFactory.getLog(getClass());

  private ProductManager prodMan;

  public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
  throws ServletException, IOException {

  String now = (new java.util.Date()).toString();
  logger.info("returning hello view with " + now);

  Map myModel = new HashMap();
  myModel.put("now", now);
  myModel.put("products", getProductManager().getProducts());

  return new ModelAndView("hello", "model", myModel);
  }

  public void setProductManager(ProductManager pm) {
  prodMan = pm;
  }

  public ProductManager getProductManager() {
  return prodMan;
  }
  }

  17. 修改View以便显示商业数据,增加对message bundle的支持

  springapp/war/WEB-INF/jsp/hello.jsp

  <%@ include file="/WEB-INF/jsp/include.jsp" %>

  <html>
  <head><title><fmt:message key="title"/></title></head>
  <body>
  <h1><fmt:message key="heading"/></h1>
  <p><fmt:message key="greeting"/> <c:out value="${model.now}"/>
  </p>
  <h3>Products</h3>
  <c:forEach items="${model.products}" var="prod">
  <c:out value="${prod.description}"/> <i>$<c:out value="${prod.price}"/></i><br><br>
  </c:forEach>
  </body>
  </html>

  18. 增加一些测试数据

  我们现在还不打算增加代码,从数据库装载商业对象。我们只springapp-servlet.xml中增加bean和messageSource设置,提供一些测试数据和对messages resource bundle的支持。

  springapp/war/WEB-INF/springapp-servlet.xml

  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

  <!--
  - Application context definition for "springapp" DispatcherServlet.
  -->

  <beans>
  <bean id="springappController" class="web.SpringappController">
  <property name="productManager">
  <ref bean="prodMan"/>
  </property>
  </bean>

  <bean id="prodMan" class="bus.ProductManager">
  <property name="products">
  <list>
  <ref bean="product1"/>
  <ref bean="product2"/>
  <ref bean="product3"/>
  </list>
  </property>
  </bean>

  <bean id="product1" class="bus.Product">
  <property name="description"><value>Lamp</value></property>
  <property name="price"><value>5.75</value></property>
  </bean>

  <bean id="product2" class="bus.Product">
  <property name="description"><value>Table</value></property>
  <property name="price"><value>75.25</value></property>
  </bean>

  <bean id="product3" class="bus.Product">
  <property name="description"><value>Chair</value></property>
  <property name="price"><value>22.79</value></property>
  </bean>

  <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">
  <property name="basename"><value>messages</value></property>
  </bean>

  <bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
  <props>
  <prop key="/hello.htm">springappController</prop>
  </props>
  </property>
  </bean>

  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
  <property name="viewClass"><value>org.springframework.web.servlet.view.JstlView</value></property>
  <property name="prefix"><value>/WEB-INF/jsp/</value></property>
  <property name="suffix"><value>.jsp</value></property>
  </bean>
  </beans>

   19. 增加message bundle

  springapp/war/WEB-INF/classes/messages.properties

  title=SpringApp
  heading=Hello :: SpringApp
  greeting=Greetings, it is now

  20. 浏览改进后的结果http://localhost:8080/springapp

  实现数据库持久层

  21. 设置HSQL数据库,在JBuilder2005中增加HSQL库,选择菜单Tools-Configure-Libraries,在弹出的对话框中点击New按钮,输入HSQL库的名称:HSQL,点击Add按钮,将lib/hsqldb目录下的文件hsqldb.jar增加到HSQL库中。

  选择菜单Enterprise-Enterprise Setup,在弹出的对话框中选择Database Drivers,按Add按钮增加HSQL库。

  选择菜单Tools-Database Pilot,然后选择菜单Files-New输入Driver:org.hsqldb.jdbcDriver,URL:jdbc:hsqldb:db/test, 双击hsqldb:db/test,输入UserName:sa,不必输入Passsword。输入如下的SQL语句并执行

  CREATE TABLE products (

  id INTEGER NOT NULL PRIMARY KEY,

  description varchar(255),

  price decimal(15,2)

  );

  CREATE INDEX products_description ON products(description);

  INSERT INTO products (id, description, price) values(1, 'Lamp', 5.78);

  INSERT INTO products (id, description, price) values(2, 'Table', 75.29);

  INSERT INTO products (id, description, price) values(3, 'Chair', 22.81);

  这样就会在JBuilder_Home/bin目录下创建一个目录db,存放了数据库test的数据

  22. 创建JDBC DAO (Data Access Object)实现

  springapp/src/db/ProductManagerDao.java

  package db;

  import bus.Product;
  import java.util.List;

  public interface ProductManagerDao {

  public List getProductList();

  public void increasePrice(Product prod, int pct);

  }

  springapp/src/db/ProductManagerDaoJdbc.java

  package db;

  import bus.Product;
  import java.util.List;
  import java.sql.ResultSet;
  import java.sql.SQLException;
  import java.sql.Types;
  import javax.sql.DataSource;
  import org.apache.commons.logging.Log;
  import org.apache.commons.logging.LogFactory;
  import org.springframework.jdbc.object.MappingSqlQuery;
  import org.springframework.jdbc.object.SqlUpdate;
  import org.springframework.jdbc.core.SqlParameter;

  public class ProductManagerDaoJdbc implements ProductManagerDao {

  /** Logger for this class and subclasses */
  protected final Log logger = LogFactory.getLog(getClass());

  private DataSource ds;

  public List getProductList() {
  logger.info("Getting products!");
  ProductQuery pq = new ProductQuery(ds);
  return pq.execute();
  }

  public void increasePrice(Product prod, int pct) {
  logger.info("Increasing price by " + pct + "%");
  SqlUpdate su = new SqlUpdate(ds, "update products set price = price * (100 + ?) / 100 where id = ?");
  su.declareParameter(new SqlParameter("increase", Types.INTEGER));
  su.declareParameter(new SqlParameter("ID", Types.INTEGER));
  su.compile();
  Object[] oa = new Object[2];
  oa[0] = new Integer(pct);
  oa[1] = new Integer(prod.getId());
  int count = su.update(oa);
  logger.info("Rows affected: " + count);
  }

  public void setDataSource(DataSource ds) {
  this.ds = ds;
  }

  class ProductQuery extends MappingSqlQuery {
  ProductQuery(DataSource ds) {
   super(ds, "SELECT id, description, price from products");
   compile();
  }

  protected Object mapRow(ResultSet rs, int rowNum) throws SQLException {
   Product prod = new Product();
   prod.setId(rs.getInt("id"));
   prod.setDescription(rs.getString("description"));
   prod.setPrice(new Double(rs.getDouble("price")));
   return prod;
  }
  }
  }

  springapp/src/bus/Product.java

  package bus;

  import java.io.Serializable;

  public class Product implements Serializable {

  private int id;
  private String description;
  private Double price;

  public void setId(int i) {
  id = i;
  }

  public int getId() {
  return id;
  }

  public void setDescription(String s) {
  description = s;
  }

  public String getDescription() {
  return description;
  }

  public void setPrice(Double d) {
  price = d;
  }

  public Double getPrice() {
  return price;
  }

  }

  springapp/src/test/TestProductManagerDaoJdbc.java

  package tests;

  import java.util.List;
  import java.util.ArrayList;
  import junit.framework.TestCase;
  import org.springframework.jdbc.datasource.DriverManagerDataSource;
  import db.ProductManagerDaoJdbc;
  import bus.Product;

  public class TestProductManagerDaoJdbc extends TestCase {

  private ProductManagerDaoJdbc pmdao;

  public void setUp() {
  pmdao = new ProductManagerDaoJdbc();
  DriverManagerDataSource ds = new DriverManagerDataSource();
  ds.setDriverClassName("org.hsqldb.jdbcDriver");
  ds.setUrl("jdbc:hsqldb:db/test");
  ds.setUsername("sa");
  ds.setPassword("");
  pmdao.setDataSource(ds);
  }

  public void testGetProductList() {
  List l = pmdao.getProductList();
  Product p1 = (Product) l.get(0);
  assertEquals("Lamp", p1.getDescription());
  Product p2 = (Product) l.get(1);
  assertEquals("Table", p2.getDescription());
  }

  public void testIncreasePrice() {
  List l1 = pmdao.getProductList();
  Product p1 = (Product) l1.get(0);
  assertEquals(new Double("5.78"), p1.getPrice());
  pmdao.increasePrice(p1, 10);
  List l2 = pmdao.getProductList();
  Product p2 = (Product) l2.get(0);
  assertEquals(new Double("6.36"), p2.getPrice());
  }

  }

  23. 修改Web应用使其使用数据库持久层

  springapp/src/bus/ProductManager.java

  package bus;

  import java.io.Serializable;
  import java.util.ListIterator;
  import java.util.List;
  import db.ProductManagerDao;

  public class ProductManager implements Serializable {

  private ProductManagerDao pmd;
  private List products;

  public void setProductManagerDao(ProductManagerDao pmd) {
  this.pmd = pmd;
  }

  /*
  public void setProducts(List p) {
  products = p;
  }
  */

  public List getProducts() {
  products = pmd.getProductList();
  return products;
  }

  public void increasePrice(int pct) {
  ListIterator li = products.listIterator();
  while (li.hasNext()) {
  Product p = (Product) li.next();
  /*
  double newPrice = p.getPrice().doubleValue() * (100 + pct)/100;
  p.setPrice(new Double(newPrice));
  */
  pmd.increasePrice(p, pct);
  }

  }

  }
