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：
?y??: 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
?y??: 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。
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);
}
}
}
