问题描述

此最小的嵌入式Jetty项目正确启动，扫描批注并查找并映射带批注的TestServlet。

项目结构：

|-src/main/java/test
|  |-Test.java
|-webapp/
|  |-test.zul
|-pom.xml

Test.java：

package test;

import java.io.File;
import java.io.IOException;
import java.net.URI;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.eclipse.jetty.annotations.AnnotationConfiguration;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.util.resource.Resource;
import org.eclipse.jetty.webapp.Configuration;
import org.eclipse.jetty.webapp.FragmentConfiguration;
import org.eclipse.jetty.webapp.MetaInfConfiguration;
import org.eclipse.jetty.webapp.WebAppContext;
import org.eclipse.jetty.webapp.WebInfConfiguration;
import org.eclipse.jetty.webapp.WebXmlConfiguration;

public class Test {
    public static void main(String[] args) throws Exception {
        Server server = new Server(8080);
        WebAppContext webapp = new WebAppContext();
        webapp.setContextPath("/test");
        webapp.setBaseResource(Resource.newResource(new File("webapp").getCanonicalFile()));
        // https://www.eclipse.org/jetty/documentation/jetty-9/index.html#configuring-webapps
        // the order is important
        webapp.setConfigurations(new Configuration[] { //
            new WebInfConfiguration(), //
            new WebXmlConfiguration(), //
            new MetaInfConfiguration(), //
            new FragmentConfiguration(), //
            // new EnvConfiguration(), // not needed
            // new PlusConfiguration(), // not needed
            new AnnotationConfiguration(), //
            // new JettyWebXmlConfiguration(), // no jetty-web.xml
        });
        webapp.setAttribute("org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern", ".*");
        server.setHandler(webapp);
        server.setDumpAfterStart(true);
        server.start();
        java.awt.Desktop.getDesktop().browse(new URI("http://localhost:8080/test/TestServlet")) /* working */;
        java.awt.Desktop.getDesktop().browse(new URI("http://localhost:8080/test/test.zul")) /* not working */;
    }
    
    @WebServlet(urlPatterns = {"/TestServlet"})
    public static final class TestServlet extends HttpServlet {
        @Override
        protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
            resp.getWriter().write("Test 1");
        }
    }
}

pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>test</groupId>
    <artifactId>test</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-annotations</artifactId>
            <version>9.4.30.v20200611</version>
        </dependency>
        <dependency>
            <groupId>org.zkoss.zk</groupId>
            <artifactId>zkbind</artifactId>
            <version>9.6.0.1</version>
        </dependency>
    </dependencies>
</project>

test.zul：

<zk><label value="hello"/></zk>

ZK网页片段似乎以某种方式被"记录"了：

|  +@ org.eclipse.jetty.webFragments.cache = java.util.concurrent.ConcurrentHashMap@bb35baa5{size=30}
|  |  +@ file:///C:/Users/r.hoehener/.m2/repository/org/zkoss/common/zcommon/9.6.0.1/zcommon-9.6.0.1.jar = org.eclipse.jetty.util.resource.EmptyResource@3fc39309
|  |  +@ file:///C:/Users/r.hoehener/.m2/repository/org/eclipse/jetty/jetty-annotations/9.4.30.v20200611/jetty-annotations-9.4.30.v20200611.jar = org.eclipse.jetty.util.resource.EmptyResource@3fc39309

|  |  +@ file:///C:/Users/r.hoehener/.m2/repository/org/apache-extras/beanshell/bsh/2.0b6/bsh-2.0b6.jar = org.eclipse.jetty.util.resource.EmptyResource@3fc39309
|  |  +@ file:///C:/Users/r.hoehener/.m2/repository/org/zkoss/zk/zkwebfragment/9.6.0.1/zkwebfragment-9.6.0.1.jar = jar:file:///C:/Users/r.hoehener/.m2/repository/org/zkoss/zk/zkwebfragment/9.6.0.1/zkwebfragment-9.6.0.1.jar!/META-INF/web-fragment.xml
...

但test.zul显示为纯文本。ZK引擎未初始化。

知道为什么吗？

编辑：为维护我进行配置的方式：这直接来自9.x文档，文档中写着"您有许多选项可以让Jetty使用不同的配置列表。"，包括"直接在WebAppContext上设置列表"：

<Configure class="org.eclipse.jetty.webapp.WebAppContext">
  <Set name="war"><SystemProperty name="jetty.base" default="."/>/webapps/my-cool-webapp</Set>
  <Set name="configurationClasses">
    <Array type="java.lang.String">
      <Item>org.eclipse.jetty.webapp.WebInfConfiguration</Item>
      <Item>org.eclipse.jetty.webapp.WebXmlConfiguration</Item>
      <Item>org.eclipse.jetty.webapp.MetaInfConfiguration</Item>
      <Item>org.eclipse.jetty.webapp.FragmentConfiguration</Item>
      <Item>org.eclipse.jetty.plus.webapp.EnvConfiguration</Item>
      <Item>org.eclipse.jetty.plus.webapp.PlusConfiguration</Item>
      <Item>org.eclipse.jetty.annotations.AnnotationConfiguration</Item>
      <Item>org.eclipse.jetty.webapp.JettyWebXmlConfiguration</Item>
    </Array>
  </Set>
</Configure>
