Question

我正在为wicket示例hello world创建项目，我正在运行应用程序，但显示页面显示HTTP状态404 - 和描述：请求的资源（）不可用。

这是我的源代码：HelloWorld.java

package com.wicket.hello;

import org.apache.wicket.PageParameters;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;

public class HelloWorld extends WebPage {

/**
 * 
 */
private static final long serialVersionUID = 1L;

public HelloWorld(final PageParameters pageParameters) {
    add(new Label("message", "Hello World"));
}
}

这是我的源代码：HelloWorld.html

<html>
<body>
    <span wicket:id="message">Message goes here</span>
</body>
</html>

这是我的源代码：HelloWorldApplication.java

package com.wicket;

import org.apache.wicket.Page;
import org.apache.wicket.protocol.http.WebApplication;

import com.wicket.hello.HelloWorld;

public class HelloWorldApplication extends WebApplication {

    @Override
    public Class<? extends Page> getHomePage() {
        // TODO Auto-generated method stub
        return HelloWorld.class;
    }

}

这是我的来源：web.xml

感谢您的帮助。

Answer 1

您可以尝试删除pom.xml的warsourcedirectory部分。

是否有任何理由使用旧的1.4.x而不是6.x版本（强制jdk7对我来说意味着你的目标是更新的系统）？

Answer 2

在构建内部的pom.xml中添加以下代码，这会将HTML文件添加到您的可部署类文件夹中，您的问题将解决

<resources>
<resource>
    <filtering>false</filtering>
<directory>src/main/resources</directory>
</resource>
<resource>
    <filtering>false</filtering>
    <directory>src/main/java</directory>
    <includes>
        <include>**</include>
    </includes>
    <excludes>
        <exclude>**/*.java</exclude>
    </excludes>
</resource>
