Java/Wicket:使用Resources编译Basic Hello World

Question

我正在关注Hello World Wicket应用程序的这个示例

https://www.ibm.com/developerworks/web/library/wa-aj-wicket/

特别是我放在HelloWorld.html我的源目录旁边HelloWorld.java.

我的文件结构如下所示:

$ tree
.
??? pom.xml
??? src
?   ??? main
?   ?   ??? java
?   ?   ?   ??? com
?   ?   ?       ??? example
?   ?   ?           ??? wicket
?   ?   ?               ??? HelloWorld.html
?   ?   ?               ??? HelloWorld.java
?   ?   ?               ??? HelloWorldApplication.java
?   ?   ??? resources
?   ?   ??? webapp
?   ?       ??? WEB-INF
?   ?           ??? web.xml
?   ??? test
?       ??? java
??? wicketTest.iml 

但是,当我将其编译为war文件,并在Jetty中加载时,我在浏览器中收到此错误:

Unexpected RuntimeException

Last cause: Can not determine Markup. Component is not yet connected to a parent. [Page class = com.example.wicket.HelloWorld, id = 4, render count = 1]

Stacktrace

Root cause:

org.apache.wicket.markup.MarkupNotFoundException: Can not determine Markup. Component is not yet connected to a parent. [Page class = com.example.wicket.HelloWorld, id = 4, render count = 1]
     at org.apache.wicket.Component.getMarkup(Component.java:737)
     at org.apache.wicket.Component.internalRender(Component.java:2344)
     at org.apache.wicket.Component.render(Component.java:2307)
     at org.apache.wicket.Page.renderPage(Page.java:1010) 

当我查看war文件时,我注意到html文件丢失了:

如何在我的POM文件中指定包含html文件？

我的POM现在很小:

<?xml version="1.0" encoding="UTF-8"?>
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>wicketTest</groupId>
    <artifactId>wicketTest</artifactId>

解决方案,如果您希望HTML在wicket最佳实践中(与您的类一起)将其添加到您的pom的构建部分.
