Question

好吧，我完全卡住了。我想在嵌入式模式下运行Tomcat，这样我就可以测试应用程序，而无需在单独的进程中运行服务器。我错过了一些简单，愚蠢和重要的东西，我需要你的帮助才能看到它。

此测试失败，出现HTTP错误400，错误请求。我试过MemoryProtocolHandler，context.invoke（），...我不知道该怎么做。也许你看到一些简单的东西。

package ca.jbrains.jsfunit.learning.test;

import org.apache.catalina.Container;
import org.apache.catalina.Context;
import org.apache.catalina.Engine;
import org.apache.catalina.connector.Connector;
import org.apache.catalina.connector.Request;
import org.apache.catalina.realm.MemoryRealm;
import org.apache.catalina.startup.Embedded;
import org.junit.After;
import org.junit.Test;

import com.gargoylesoftware.htmlunit.WebClient;

public class LearnEmbeddedTomcatTest {
    private Embedded embedded;
    private Container host;
    private Engine engine;

    @Test
    public void deploySampleApplicationFromFileSystem() throws Exception {
        String tomcatPath = "/Users/jbrains/ThirdParty/apache-tomcat-5.5.28-embed";

        // Create an embedded server
        embedded = new Embedded();
        embedded.setCatalinaHome(tomcatPath);
        embedded.setRealm(new MemoryRealm());

        // Create an engine
        engine = embedded.createEngine();
        engine.setDefaultHost("localhost");

        // Create a default virtual host
        host = embedded.createHost("localhost", tomcatPath + "/webapps");
        engine.addChild(host);

        // Create an application context
        Context context = embedded.createContext("TddJsfWeb", tomcatPath
                + "/webapps/TddJsfWeb");
        host.addChild(context);

        // Install the assembled container hierarchy
        embedded.addEngine(engine);

        // Assemble and install a default HTTP connector
        Connector connector = embedded.createConnector("localhost", 8080,
                "http");
        embedded.addConnector(connector);

        // Start the embedded server
        embedded.setAwait(true);
        embedded.start();

        WebClient webClient = new WebClient();
        webClient.getPage("http://localhost:8080/TddJsfWeb/static.xhtml");
    }
}

解压缩的.war绝对位于/Users/jbrains/ThirdParty/apache-tomcat-5.5.28-embed/webapps/TddJsfWeb/...，而static.xhtml位于解压缩的.war文件夹的根目录中。

拜托，请告诉我我有多愚蠢。感谢。

我和Tomcat有类似的经历。我最终使用了Jetty - 从代码的角度来管理起来要简单得多。

Answer 2

我希望second Jetty over Tomcat for this ..要运行Jetty，我需要的是：

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

import org.mortbay.jetty.Connector;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.bio.SocketConnector;
import org.mortbay.jetty.webapp.WebAppContext;

public class StartJetty {
       public static void main(String[] args) throws Exception {
               Server server = new Server();
               SocketConnector connector = new SocketConnector();
               // Set some timeout options to make debugging easier.
               connector.setMaxIdleTime(1000 * 60 * 60);
               connector.setSoLingerTime(-1);
               connector.setPort(8081);
               server.setConnectors(new Connector[] { connector });

               WebAppContext bb = new WebAppContext();
               bb.setServer(server);
               bb.setContextPath("/");
               bb.setWar("src/main/webapp");
               server.addHandler(bb);

               try {
                       System.out.println(">>> STARTING EMBEDDED JETTY SERVER, PRESS ANY
KEY TO STOP");
                       server.start();

                       //Launch browser
                       if (Desktop.isDesktopSupported())
                               if (Desktop.getDesktop().isSupported(Desktop.Action.BROWSE))
                                       try {
                                               Desktop.getDesktop().browse(new URI("http://localhost:8081/"));
                                       }
                                       catch (IOException ioe) {
                                               ioe.printStackTrace();
                                       }
                                       catch (URISyntaxException use) {
                                               use.printStackTrace();
                                       }

                       System.in.read();
                       System.out.println(">>> STOPPING EMBEDDED JETTY SERVER");
                       server.stop();
                       server.join();
               }
               catch (Exception e) {
                       e.printStackTrace();
                       System.exit(100);
               }
       }
}

如果Jetty适合您，那就太棒了，但是如果您想深入了解Tomcat，您可以在发出请求之前浏览一下您的应用程序并查看它们是否可用。

for (Container cont : host.findChildren()) {
    if (cont instanceof StandardContext) {
        StandardContext ctx = (StandardContext) cont;
        ServletContext servletContext = ctx.getServletContext();
        log.debug("Context initialized: {}", servletContext.getContextPath());
        String prefix = servletContext.getRealPath("/");
        try {
            if (ctx.resourcesStart()) {
                log.debug("Resources started");
            }
            log.debug("Context - available: {} privileged: {}, start time: {}, reloadable: {}", new Object[] { ctx.getAvailable(), ctx.getPrivileged(), ctx.getStartTime(), ctx.getReloadable() });
...

第三种选择是查看比Tomcat或Jetty更简单的simpiler容器，例如Winstone：http://winstone.sourceforge.net/

嵌入Tomcat并向已部署的应用程序发出请求
