1. Establishment of basic applications and environments
(Translator: This tutorial is originally used by Ant manual compilation and deployment, where there is a different place to use the Eclipse development environment, you can refer to the original text)
(1) Development environment
l Java SDK 1.4.2
l apache tomcat 5.0.25
l Eclipse 3.0
l Eclipse plugin:
Ø EMF SDK 2.0.1: ECLIPSE modeling framework, Lomboz plugin, you can use Runtime version)
Ø Lomboz 3.0: J2EE plugin for developing J2EE applications in Eclipse
Ø Spring IDE 1.0.3: Spring Bean Configuration Management Plugin
l Springframework 1.0.2
(2) Plug-in configuration
The following is a simply talking about the main configuration of the above plugin in Eclipse:
Lomboz
l Window / Customize Perspective / Shoutcuts / New: Select Java / Lomboz J2EE Wizards / Lomboz J2ee Project
l Window / Customize Perspective / Commands: Check Lomboz Actions
l Window / Preferences / Lomboz: Specify the location of JDK Tools.jar
l Window / Preferences: Select Server Types to apache tomcat v5.0.x, specify Tomcat installation directory, HTTP access address and port number (Translator: Use 8888), and ClassPath variables in Properties Tomcat_home value (ie Tomcat installation directory)
Spring IDE
l WINDOW / CUSTOMIZE PERSPECTIVE / SHOUTCUTS / SHOW View: Select Spring Ide
(3) Creating a J2EE project
l File / New / Lomboz J2EE Project
l Project settings: Specify project name SpringApp
l Java settings: Note that the default output directory is bin, change to SpringApp / SpringApp / Web-INF / CLASSES
l Create J2EE Module: Select the web modules page, click the Add button to specify the web module name SpringApp; select the Targeted Servers page, Type Select Apache Tomcat V5.0.x, click Add buttons to increase
l Click the finish button to complete the creation of the project.
(4) INDEX.JSP
Create an application's entry page INDEX.JSP, here is just a test of the environment:
eXample :: spring application </ title> </ head></p>
<p><body></p>
<p><H1> EXAMPLE - Spring Application </ h1> <p> this is my test. </ p></p>
<p></ body></p>
<p></ html></p>
<p>(5) Deploy the application to Tomcat</p>
<p>l On the toolbar, click the Press to Open A J2EE Project Outline button, open the Lomboz J2EE VIEW view</p>
<p>l Select the SpringApp module of SpringApp project in the modules page, right click to select Deploy</p>
<p>(6) Test application</p>
<p>l In the browser, enter http: // localhost: 8888 / springApp, see the normal test page, indicating that the environment has been established.</p>
<p>l The following starts to develop Spring MVC applications</p>
<p>(7) Modify the web-inflicity of Web.xml</p>
<p>l Define DispatCherServlets to control all requests, while having a standard servlet-maping map to * .htm URL mode</p>
<p><servlet></p>
<p><servlet-name> SpringApp </ servlet-name></p>
<p><servlet-class> Org.springframework.web.servlet.dispatcherServlet </ servlet-class></p>
<p><load-on-startup> 1 </ load-on-startup></p>
<p></ servlet></p>
<p><servlet-mapping></p>
<p><servlet-name> SpringApp </ servlet-name></p>
<p><url-pattern> *. htm </ url-pattern></p>
<p></ servlet-maping></p>
<p>l Create SpringApp-Servlet.xml (App Program Name --Servlet.xml), configure the web application for DispatcherServlet to use Context</p>
<p>Ø Define the bean entry named SpringAppController, point to the SpringAppController controller</p>
<p>Ø Use SimpleurlHandlerMapping to define the URL mapping, map the /hello.htm to the SpringAppController controller</p>
<p><? XML Version = "1.0" encoding = "UTF-8"?></p>
<p><! Doctype beans public "- // Spring // DTD bean // en" "http://www.springframework.org/dtd/spring-beans.dtd"></p>
<p><! -</p>
<p>- Application Context Definition for "SpringApp" DispatcherServlet.</p>
<p>-></p>
<p><beans></p>
<p><bean id = "SpringAppController" class = "springappcontroller" /></p>
<p><bean id = "urlmapping" class = "org.springframework.web.servlet.Handler.SIMPLEURLHANDLERMAPPING"></p>
<p><Property Name = "MAppings"> <props></p>
<p><prop key = "/ hello.htm> SpringAppController </ prop></p>
<p></ prOPS></p>
<p></ Property></p>
<p></ bean></p>
<p></ beans></p>
<p>l (Translator: Supplement Spring IDE)</p>
<p>Ø Select SpringApp project, right click to select Add Spring Beans Project Nature, the original J symbol turns S.</p>
<p>Ø Window / show View / Spring Beans, Open Spring Beans View</p>
<p>Ø Select SpringApp in the view, right click to select Properties</p>
<p>Ø Click the Add button in the config files page to join SpringApp-Servlet.xml</p>
<p>Ø In the Spring Beans view, you can see the tree of springapp-servlet.xml, double-click SpringApp-servlet.xml to open files, double-click the specific structure, automatically position</p>
<p>Ø Select SpringApp-servlet.xml, right click to select Show Graph, you can display the view structure of the file</p>
<p>(8) Copy Jars to Web-INF / LIB Directory</p>
<p>l Import Dist / Spring.jar, LIB / JAKARTA-COMMONS / Commons-Logging.jar, Lib / Log4j / Log4j-1.2.8.jar file into the springapp / web-inf / lib directory of SpringApp project</p>
<p>(9) Creating a controller</p>
<p>l HandleRequest () method to implement the Controller interface to process the request</p>
<p>l Add logging here to check if you are executed</p>
<p>l HandleRequest () Method Returned ModelandView not specified Model, so redirect to the specified view hello.jsp</p>
<p>Import Org.SpringFramework.Web.Servlet.mvc.controller;</p>
<p>Import org.springframework.Web.Servlet.ModelandView;</p>
<p>Import javax.servlet.servletException;</p>
<p>Import javax.servlet.http.httpservletRequest;</p>
<p>Import javax.servlet.http.httpservletResponse;</p>
<p>Import java.io.ioException;</p>
<p>Import org.apache.commons.logging.log;</p>
<p>Import org.apache.commons.logging.logfactory;</p>
<p>Public Class SpringAppController Implements Controller {</p>
<p>/ ** Logger for this class and subclasses * /</p>
<p>Protected final log logger = logfactory.getlog (getclass ());</p>
<p>Public ModlandView HandleRequest (httpservletRequest Request, HttpservletResponse Response)</p>
<p>Throws servletexception, IOException {Logger.info ("SpringAppController - Returning Hello View");</p>
<p>Return New ModelandView ("Hello.jsp");</p>
<p>}</p>
<p>}</p>
<p>(10) Creating view hello.jsp</p>
<p><html></p>
<p><head> <title> eXample :: spring application </ title> </ head></p>
<p><body></p>
<p><H1> Hello - Spring Application </ h1></p>
<p><p> greetings. </ p></p>
<p></ body></p>
<p></ html></p>
<p>(11) Copy and modify Log4j.properties</p>
<p>l Springframework uses the log4j record log, so import Samples / PetClinic / War / Web-INF / CLASSES / LOG4J.PROPERTIES file to the SpringApp / Web-INF / CLASSES directory of SpringApp project</p>
<p>l Modify log4j.properties, specify the log output file:</p>
<p># For jboss: Avoid to setup log4j outside $ jboss_home / server / default / deploy / log4j.xml!</p>
<p># For all other servers: Comment Out the log4j listener in web.xml too.</p>
<p># log4j.rootlogger = info, stdout, logfile</p>
<p>Log4j.appender.stdout = org.apache.log4j.consoleAppender</p>
<p>Log4j.Appender.stdout.Layout = Org.apache.log4j.patternlayout</p>
<p>Log4j.Appender.stdout.Layout.conversionPattern =% D% p [% C] - <% m>% N</p>
<p>Log4j.Appender.logfile = org.apache.log4j.rollingfileappender</p>
<p>Log4j.Appender.logfile.file = $ {Springapp.Root} /web-inf/springapp.log</p>
<p>Log4j.Appender.logfile.maxfilesize = 512KB</p>
<p># Keep Three Backup Files.</p>
<p>Log4j.Appender.logfile.maxbackupindex = 3</p>
<p># Pattern to output: Date Priority [category] - Message</p>
<p>Log4j.Appender.logfile.Layout = org.apache.log4j.patternlayout</p>
<p>Log4j.Appender.logfile.Layout.conversionPattern =% D% p [% C] -% M% N</p>
<p>L (Translator: Tips below when deploying, log4j does not work properly, looking high of high finger)</p>
<p>Log4j: warn no appenders could be found for logger (org.apache.catalina.session.managerbase).</p>
<p>Log4J: Warn Please Initialize The log4j system prot in.</p>
<p>(12) Re-deploy the application L Re-deploy the application via the previous method</p>
<p>l (Translator: Before re-deployment, you need to remove the SpringApp directory under Tomcat's WebApps directory, otherwise Tomcat will not extract the new WAR file. What is the problem?)</p>
<p>l Enter http: // localhost: 8888 / springApp / hello.htm, you can display the content of Hello.jsp.</p></div><div class="text-center mt-3 text-grey">
