我正在尝试为Confluence制作一个"hello world"servlet插件.在atlassian-plugin.xml中,我有

<servlet name="testservlet" key="testservlet" class="com.test.confluence.plugins.testservlet.TestServlet">
    <description>A test servlet.</description>
    <url-pattern>/testservlet</url-pattern>
</servlet>

在pom.xml中,我有

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

这是servlet

package com.test.confluence.plugins.testservlet;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

public class TestServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        out.println("Hello World");
        out.close();
    }
}

它构建和安装,但是当我在/ confluence/plugins/servlet/testservlet上访问servlet时,我得到一个找不到的页面,并且这个ClassCastException:

[INFO] [talledLocalContainer]  -- url: /confluence/plugins/servlet/testservlet | userName: admin
[INFO] [talledLocalContainer] com.atlassian.util.concurrent.LazyReference$InitializationException: java.lang.ClassCastException: com.test.confluence.plugins.testservlet.TestServlet cannot be cast to javax.servlet.http.HttpServlet

编辑:这是完整的堆栈跟踪:

[INFO] …

我想显示以下内容:

 <ul class="parent">
    <li>a
        <ul class="child">
            <li>a1</li>
            <li>a2</li>
            <li>a3</li>
        </ul>
    </li>
    <li>b
        <ul class="child">
            <li>b1</li>
            <li>b2</li>
            <li>b3</li>
        </ul>
    </li>
</ul>

像这样:

*a        *b
  *a1       *b1
  *a2       *b2
  *a3       *b3

我尝试了一些使用内联和浮动的变体,但找不到让孩子菜单垂直扩展并使用CSS排队的方法.
