利用JBuilder 2005 開(kāi)發(fā)Spring實(shí)例

2010-08-28 10:45:06來(lái)源:西部e網(wǎng)作者:

  1. 下載spring包,網(wǎng)址如下:

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

  解壓后的目錄中包含了dist、lib等子目錄

  2. 在JBuilder2005中增加spring庫(kù),選擇菜單Tools-Configure-Libraries,在彈出的對(duì)話框中點(diǎn)擊New按鈕,輸入spring庫(kù)的名稱:spring,點(diǎn)擊Add按鈕,將dist目錄中的所有jar文件增加到spring庫(kù)中

  3. 新建工程文件,選菜單File-New Project,給工程文件取名為myProject

  設(shè)置工程文件的屬性,選菜單Project-Project Properties,選擇Tomcat作為服務(wù)器,將spring庫(kù)加入Path/Required Libraries。因?yàn)槔又杏玫搅薼og4j,將包含了log4j的庫(kù)加入Path/Required Libraries,注意到lib目錄下有兩個(gè)子目錄log4j和jakarta-commons,它們的用法是不同的,如下面的代碼片斷所示:

  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模塊,選菜單File-New,給Web模塊取名為springapp

  5. 新建hello.jsp文件如下:

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

  6. 新建類文件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>

。約ervlet>
 。約ervlet-name>springapp</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 。糽oad-on-startup>1</load-on-startup>
。/servlet>

。約ervlet-mapping>
  <servlet-name>springapp</servlet-name>
 。紆rl-pattern>*.htm</url-pattern>
 </servlet-mapping>

。紈elcome-file-list>
 。紈elcome-file>
   index.jsp
 。/welcome-file>
。/welcome-file-list>

</web-app>

  8. 在web-inf目錄中新建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"/>
。糱ean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
。紁roperty name="mappings">
 。紁rops>
   <prop key="/hello.htm">springappController</prop>
 。/props>
。/property>
</bean>

</beans>

  9. 在web-inf目錄中新建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. 設(shè)置web模塊springapp的屬性Content,加入文件log4j.properties,因?yàn)閏lasses目錄是自動(dòng)產(chǎn)生的,這一步是為了把文件log4j.properties加到classes目錄。

  11. 設(shè)置Run Configuration,選菜單Run-Configurations,新建一個(gè)Run Configuration,Type選Server,Launch URI設(shè)置為:/springapp/hello.htm,給它取名為hello

  12. 運(yùn)行,你會(huì)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>

  這說(shuō)明你已成功建立了基本的spring應(yīng)用。

  jstl的支持,設(shè)置工程文件的屬性,選菜單Project-Project Properties,將jstl庫(kù)加入Path/Required Libraries。

  14. 改進(jìn)前面的例子,改進(jìn)的文件如下:

  增加“header”文件include.jsp,這是一些jsp文件的公用部分,這樣可以使得開(kāi)發(fā)和維護(hù)更容易。所有jsp文件放在web-inf/jsp目錄下,為的是只有Controller可以訪問(wèn)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>將頁(yè)面重定向到Controller,這樣就建立了index.jsp和應(yīng)用架構(gòu)的聯(lián)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>標(biāo)記,把從Model提取的,傳遞給View的當(dāng)前日期和時(shí)間作為輸出。

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

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

<html>
<head><title>Hello :: Spring Application</title></head>
<body>
。糷1>Hello - Spring Application</h1>
 <p>Greetings, it is now <c:out value="${now}"/>
 </p>
</body>
</html>


  在SpringappController.java中增加包含了當(dāng)前日期和時(shí)間的string作為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. 瀏覽改進(jìn)后的結(jié)果http://localhost:8080/springapp,首先訪問(wèn)index.jsp,然后重定向到hello.htm,接著把控制交給Controller,Controller把日期和時(shí)間傳送給View。

  只能在瀏覽器這樣測(cè)試。在JBuilder2005中設(shè)置Run Configuration不能訪問(wèn)http://localhost:8080/springapp,但可以訪問(wèn)http://localhost:8080/springapp/index.jsp

  在上面的例子中,Controller指定了View的完全路徑,使得Controller和View之間存在不必要的依賴。為了移出這種依賴,我們可以用類ResourceBundleViewResolver 和 a SimpleUrlHandlerMapping在屬性文件中定義這種依賴,對(duì)于簡(jiǎn)單的情形,我們也可以利用InternalResourceViewResolver設(shè)置前綴和后綴,下面就用第二種方法。修改文件springapp-servlet.xml包含ViewResolver設(shè)置,我們還選擇使用JstlView,這使得我們可以結(jié)合使用JSTL和message resource bundles,因此可以支持國(guó)際化。

  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>
。糱ean id="springappController" class="SpringappController"/>

。糱ean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
 <property name="mappings">
 。紁rops>
   <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>


  現(xiàn)在,我們就可以移出Controller中View名稱的前綴和后綴了。

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);
 }
}


  這樣修改后的例子應(yīng)該仍能運(yùn)行。

  16. 增加商業(yè)邏輯類

  為了分開(kāi)Web邏輯和商業(yè)邏輯,我們建立兩個(gè)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以便顯示商業(yè)數(shù)據(jù),增加對(duì)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. 增加一些測(cè)試數(shù)據(jù)

  我們現(xiàn)在還不打算增加代碼,從數(shù)據(jù)庫(kù)裝載商業(yè)對(duì)象。我們只springapp-servlet.xml中增加bean和messageSource設(shè)置,提供一些測(cè)試數(shù)據(jù)和對(duì)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">

<!--

-->

<beans>
 <bean id="springappController" class="web.SpringappController">
。紁roperty name="productManager">
 。紃ef bean="prodMan"/>
 </property>
</bean>

<bean id="prodMan" class="bus.ProductManager">
<property name="products">
。糽ist>
 。紃ef bean="product1"/>
 。紃ef bean="product2"/>
 。紃ef bean="product3"/>
。/list>

</bean>

<bean id="product1" class="bus.Product">

</bean>

<bean id="product2" class="bus.Product">

  <property name="price"><value>75.25</value></property>
</bean>

<bean id="product3" class="bus.Product">

 <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. 瀏覽改進(jìn)后的結(jié)果http://localhost:8080/springapp

  實(shí)現(xiàn)數(shù)據(jù)庫(kù)持久層

  21. 設(shè)置HSQL數(shù)據(jù)庫(kù),在JBuilder2005中增加HSQL庫(kù),選擇菜單Tools-Configure-Libraries,在彈出的對(duì)話框中點(diǎn)擊New按鈕,輸入HSQL庫(kù)的名稱:HSQL,點(diǎn)擊Add按鈕,將lib/hsqldb目錄下的文件hsqldb.jar增加到HSQL庫(kù)中。

  選擇菜單Enterprise-Enterprise Setup,在彈出的對(duì)話框中選擇Database Drivers,按Add按鈕增加HSQL庫(kù)。

  選擇菜單Tools-Database Pilot,然后選擇菜單Files-New輸入Driver:org.hsqldb.jdbcDriver,URL:jdbc:hsqldb:db/test, 雙擊hsqldb:db/test,輸入U(xiǎn)serName:sa,不必輸入Passsword。輸入如下的SQL語(yǔ)句并執(zhí)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);

  這樣就會(huì)在JBuilder_Home/bin目錄下創(chuàng)建一個(gè)目錄db,存放了數(shù)據(jù)庫(kù)test的數(shù)據(jù)

  22. 創(chuàng)建JDBC DAO (Data Access Object)實(shí)現(xiàn)

  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應(yīng)用使其使用數(shù)據(jù)庫(kù)持久層

  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);
}

}

}
