Spring Application/h1 5: pThis is my test./p 6: pa hrefhello.htmlSay Hello/a/p 7: /body 8: /html 然后加个目录WEB-INF。里面加一个文件web.xml这个文件很重要是web项目最重要的配置文件(有关Servlet这个是java web的核心概念。) 1: ?xml version1.0 encodingUTF-8? 2: 3: web-app version2.4 4: xmlnshttp://java.sun.com/xml/ns/j2ee 5: xmlns:xsihttp://www.w3.org/2001/XMLSchema-instance 6: xsi:schemaLocationhttp://java.sun.com/xml/ns/j2ee 7: http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd 8: 9: display-nameSpring3MVC/display-name 10: servlet 11: servlet-namespringapp/servlet-name 12: servlet-classorg.springframework.web.servlet.DispatcherServlet/servlet-class 13: load-on-startup1/load-on-startup 14: /servlet 15: 16: servlet-mapping 17: servlet-namespringapp/servlet-name 18: url-pattern*.html/url-pattern 19: /servlet-mapping 20: 21: welcome-file-list 22: welcome-file 23: index.jsp 24: /welcome-file 25: /welcome-file-list 26: 27: /web-app 加一个文件srpingapp-servlet.xml 1: ?xml version1.0 encodingUTF-8? 2: beans xmlnshttp://www.springframework.org/schema/beans 3: xmlns:xsihttp://www.w3.org/2001/XMLSchema-instance 4: xmlns:phttp://www.springframework.org/schema/p 5: xmlns:contexthttp://www.springframework.org/schema/context 6: xsi:schemaLocationhttp://www.springframework.org/schema/beans 7: http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 8: http://www.springframework.org/schema/context 9: http://www.springframework.org/schema/context/spring-context-3.0.xsd 10: 11: context:component-scan base-packagenet.spring.controller / 12: 13: !-- the application context definition for the springapp DispatcherServlet -- 14: !-- bean name/hello.html classnet.spring.controller.HelloWorldController/ -- 15: 16: bean idviewResolver 17: classorg.springframework.web.servlet.view.UrlBasedViewResolver 18: property nameviewClass 19: valueorg.springframework.web.servlet.view.JstlView / 20: property nameprefix value/WEB-INF/jsp/ / 21: property namesuffix value.jsp / 22: /bean 23: /beans 在WEB-INF加两个目录jsp和lib。首先复制引用的jar包例如Spring的jar然后在lib目录上粘贴要引用这些jar 然后右键选择项目属性Build path… Configure build path. Libraries – add jars…把这些lib下面的jar加入引用。 说一下目录结构通常src存放Java源文件classes存放编译后的class文件lib存放编译和运行用到的所有jar文件web存放JSP等web文件dist存放打包后的jar文件doc存放API文档。 在jsp目录下添加include.jsp: 1: % page sessionfalse% 2: % taglib prefixc urihttp://java.sun.com/jsp/jstl/core % 3: % taglib prefixfmt urihttp://java.sun.com/jsp/jstl/fmt % 添加hello.jsp注意里面用了Model里面的message 1: % include file/WEB-INF/jsp/include.jsp % 2: 3: html 4: headtitleHello :: Spring Application/title/head 5: body 6: h1Hello - Spring Application/h1 7: pGreetings./p 8: pMessage: c:out value${message}//p 9: /body 10: /html Ant编译和自动部署到Tomcat 为了让Eclipse用我们的Ant编译和build.xml文件需要设置一下Eclipse项目属性Builders把java builder去掉勾然后New…一个选择Ant builder….然后选择build.xml如图 确定了以后点击菜单 project – Build all … 自动Ant编译 1: Buildfile: C:\Users\GatesBill\workspace\springapp\build.xml 2: 3: usage: 4: [echo] springapp build file 5: [echo] ----------------------------------- 6: [echo] Available targets are: 7: [echo] build -- Build the application 8: [echo] deploy -- Deploy application as directory 9: [echo] deploywar -- Deploy application as a WAR file 10: [echo] install -- Install application in Tomcat 11: [echo] reload -- Reload application in Tomcat 12: [echo] start -- Start Tomcat application 13: [echo] stop -- Stop Tomcat application 14: [echo] list -- List Tomcat applications 15: BUILD SUCCESSFUL 16: Total time: 989 milliseconds 看了一下源码果然已经编译好了 但是没有自动部署到Tomcat的webapps里面我们需要运行Ant deploy在项目属性Builders选择刚才我们新建的那个Ant编译选择edit然后里面Argument的地方输入deploy然后ApplyOK。再次编译就自动部署Tomcat了 1: Buildfile: C:\Users\GatesBill\workspace\springapp\build.xml 2: 3: build: 4: [javac] Compiling 1 source file to C:\Users\GatesBill\workspace\springapp\war\WEB-INF\classes 5: [javac] warning: [options] bootstrap class path not set in conjunction with -source 1.5 6: [javac] 1 warning 7: 8: deploy: 9: [copy] Copying 11 files to C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\springapp 10: BUILD SUCCESSFUL 11: Total time: 4 seconds 也可以用命令行的方式执行Ant编译这样我们可以另外写一个deploy的bat脚本非常方便不过要首先到computer – properties – advanced - 环境变量添加下列环境变量 ANT_HOMEAnt解压目录通常在Eclipse的plugin目录下Path…;%ANT_HOME%\bin 然后打开command如果在win7下可能需要提升administration 权限转到springapp目录为当前目录然后执行ant deploy 即可如下图 到Tomcat的目录下webapps一看果然有了springapp然后在浏览器打开Tomcat的managerhttp://localhost:8080/manager/html点击我们的网站springapp有了 点击say hello链接到http://localhost:8080/springapp/hello.html 上面这个message是从controller传给model的。 Build Error: taskdef class org.apache.catalina.ant.InstallTask cannot be found 如果得到这个错误一般是因为安装的Tomcat 7而不是Tomcat 6.0因为在Tomcat 7.0下面要修改下build.xml 1 taskdef nameinstall classnameorg.apache.catalina.ant.InstallTask2 classpath refidcatalina-ant-classpath/3 /taskdef 要改成 1 taskdef nameinstall classnameorg.apache.catalina.ant.DeployTask2 classpath refidcatalina-ant-classpath/3 /taskdef 总结 用Ant编译和部署到Tomcat还是非常爽的过程很流畅。喜欢这种感觉。转载于:https://www.cnblogs.com/Mainz/archive/2012/04/14/2447786.html
