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
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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,注重到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 {
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
/** Logger for this class and subclasses */
static Logger logger = Logger.getLogger(SpringappController.class);
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
jakarta-commons
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
public class SpringappController implements Controller {
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
/** 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
headtitleExample :: Spring Application/title/head
body
h1Hello - Spring Application/h1
pGreetings./p
/body
/html
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
6. 新建类文件SpringappController.Java如下:
package spring;
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.ModelAndView;
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
import java.io.IOException;
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
//import org.apache.commons.logging.Log;
//import org.apache.commons.logging.LogFactory;
import org.apache.log4j.Level;
import org.apache.log4j.Logger;
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
public class SpringappController implements Controller {
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
/** Logger for this class and subclasses */
// protected final Log logger = LogFactory.getLog(getClass());
static Logger logger = Logger.getLogger(SpringappController.class);
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
logger.info("SpringappController - returning hello view");
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
return new ModelAndView("hello.jsp");
}
}
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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-namespringapp/servlet-name
servlet-classorg.springframework.web.servlet.DispatcherServlet/servlet-class
load-on-startup1/load-on-startup
/servlet
servlet-mapping
servlet-namespringapp/servlet-name
url-pattern*.htm/url-pattern
/servlet-mapping
welcome-file-list
welcome-file
index.jsp
/welcome-file
/welcome-file-list
/web-app
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
8. 在web-inf目录中新建springapp-servlet.xml文件如下
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
?xml version="1.0" encoding="UTF-8"?
!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
!--
- Application context definition for "springapp" DispatcherServlet.
--
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
beans
bean id="springappController" class="spring.SpringappController"/
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"
property name="mappings"
props
prop key="/hello.htm"springappController/prop
/props
/property
/bean
/beans
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
9. 在web-inf目录中新建log4j.properties文件如下:
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
log4j.rootCategory=INFO, stdout, logfile
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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] - messageline_separator
log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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'
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
这说明你已成功建立了基本的spring应用。

13. 增加对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轻易。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" %
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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"/
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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
headtitleHello :: Spring Application/title/head
body
h1Hello - Spring Application/h1
pGreetings, it is now c:out value="${now}"/
/p
/body
/html
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
在SpringappController.java中增加包含了当前日期和时间的string作为Model
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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);
}
}
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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靠。为了移出这种依靠,我们可以用类ResourceBundleViewResolver 和 a SimpleUrlHandlerMapping在属性文件中定义这种依靠,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。
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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"valueorg.springframework.web.servlet.view.JstlView/value/property

property name="suffix"value.jsp/value/property
/bean
/beans
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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);
}
}
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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;
}
}
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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;
}
}
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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;
}
}
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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
headtitlefmt:message key="title"//title/head
body
h1fmt:message key="heading"//h1
pfmt:message key="greeting"/ c:out value="${model.now}"/
/p
h3Products/h3
c:forEach items="${model.products}" var="prod"
c:out value="${prod.description}"/ i$c:out value="${prod.price}"//ibrbr
/c:forEach
/body
/html
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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。

19. 增加message bundle
springapp/war/WEB-INF/classes/messages.properties
title=SpringApp
heading=Hello :: SpringApp
greeting=Greetings, it is now

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
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
CREATE TABLE products (
id INTEGER NOT NULL PRIMARY KEY,
description varchar(255),
price decimal(15,2)
);
CREATE INDEX products_description ON products(description);
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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);
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)

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
(本文来源于图老师网站,更多请访问http://www.tulaoshi.com/bianchengyuyan/)
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);
}

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;
}

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;

while (li.hasNext()) {
Product p = (Product) li.next();
/*
double newPrice = p.getPrice().doubleValue() * (100 + pct)/100;
p.setPrice(new Double(newPrice));
