• 用Jetty快速开发J2EE应用



    对于用Maven管理的项目,可以使用Maven的Jetty插件启动应用进行快速测试。项目的pom.xml配置如下:

    之后在命令行输入mvn jetty:run即可启动应用程序。Jetty插件自动将src/main/webapp作为Web应用的根目录。

    此外,也可以按照下面的方法用main()方法来启动应用。
    package com.cdai.web.ssh;
    
    import java.io.File;
    
    import org.eclipse.jetty.server.Server;
    import org.eclipse.jetty.webapp.WebAppContext;
    
    public class JettyRunner {
    
    	public static void main(String[] args) throws Exception {
    
    		String contextPath = "/cdai";
    		int port = Integer.getInteger("port", 8080);
    
    		Server server = createServer(contextPath, port);
    
    		try {
    			server.start();
    			server.join();
    		} catch (Exception e) {
    			e.printStackTrace();
    			System.exit(100);
    		}
    	}
    
    	private static Server createServer(String contextPath, int port) {
    		//use Eclipse JDT compiler
    		System.setProperty("org.apache.jasper.compiler.disablejsr199", "true");
    
    		Server server = new Server(port);
    		server.setStopAtShutdown(true);
    
    		String warFile = "src/main/webapp";
    		WebAppContext context = new WebAppContext(warFile, contextPath);
    		context.setServer(server);
    
    		//设置work dir,war包将解压到该目录,jsp编译后的文件也将放入其中。
    		String currentDir = new File(warFile).getParent();
    		File workDir = new File(currentDir, "work");
    		context.setTempDirectory(workDir);
    
    		server.setHandler(context);
    		return server;
    	}
    
    }
    但是在使用Struts2时,Jetty找不到struts2标签报错,不知道有没有人碰到过。为什么main()方法启动的Jetty不会自动去Jar中
    找struts2标签配置文件呢?应该怎样配置Jetty去解决?

    以下是Jetty插件默认的配置。存放JSP编译结果的临时目录不再是main()方法启动时的src/main/work,而是target/tmp。
