有时候,我们需要的一个简单的不能再简单的web应用,通常我这时候会用jetty来实现一个嵌入式的web容器,写一个bat,鼠标点一下就能跑起来。 目录结构:
引用---App
---www
---WEB-INF
---web.xml
---index.gsp
---index.groovy
---logs
---lib
---commons-logging.jar
---groovy-all-1.5.7.jar

app.groovy(启动脚本):
import org.mortbay.http.HttpContext; import org.mortbay.http.HttpListener; import org.mortbay.http.NCSARequestLog; import org.mortbay.http.SocketListener; import org.mortbay.http.SslListener; import org.mortbay.http.handler.MsieSslHandler; import org.mortbay.jetty.Server; import org.mortbay.jetty.servlet.WebApplicationContext; //应用定义 def port = 8089 def approot = ["/":"www"]//虚拟目录,支持多个["/":"www","/demo":"demo"] SocketListener listener = new SocketListener(); listener.setPort(port); listener.setMinThreads(5); listener.setMaxThreads(100); listener.setMaxIdleTimeMs(30000); listener.setLowResourcePersistTimeMs(2000); listener.setAcceptQueueSize(0); Server server = new Server(); server.addListener(listener); server.setRequestsPerGC(2000); server.setStatsOn(false); approot.each(){key,value -> server.addWebApplication(key, value); } server.start();
request.setAttribute("user","1111") context.getRequestDispatcher("/index.gsp?iuser=admin").forward(request,response)
index.gsp(例子):
Java代码<% println params.iuser println request.getAttribute("user") println request.remoteHost println headers.host %>
Java代码
