eclipse - Wicket 口异常开始过滤器 Wicket 口

Question

我正在尝试使用 wicket 创建一个网络应用程序。这些是我遵循的步骤:

1. 我使用这个命令创建了一个 maven 项目:

   mvn 原型(prototype):生成 -DarchetypeGroupId=org.apache.wicket -DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=6.6.0 -DgroupId=com.mycompany -DartifactId=myproject -DarchetypeRepository= https://repository.apache.org/ -DinteractiveMode=false

2. 我把项目导入eclipse

3. 我通过右键单击启用了 Maven 依赖项
4. 我将我的项目转换为 Web 项目并设置了 Tomcat 7 服务器
5. 通过右键单击我在此服务器上运行项目，生成消息:HTTP 状态 404 - 请求的资源不可用。

这是控制台上的错误消息:

        <param-name>applicationClassName</param-name>
        <param-value>com.mycompany.WicketApplication</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>wicket.myproject</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

谁能帮帮我？？？？

Answer 1

有点晚了，但这是解决问题的方法:

右键单击项目 -> 属性 -> 部署程序集

请确保项目的库已部署到 WEB-INF/lib 文件夹中。在我的例子中，根本没有库，所以我必须通过按

添加它们

添加 -> Java 构建路径条目

并选择库(其中有 wicket 库)
