的Java /檢票：編譯基本的Hello World與資源

Question

我下面一個Hello World Wicket應用程序

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

特別是我在源目錄放置HelloWorld.html旁邊HelloWorld.java的這個例子。

我的文件結構如下：

$ 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 

然而，當我編譯這一場戰爭的文件，並在碼頭裝載，我收到此錯誤，在瀏覽器中：

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) 

當我看在戰爭文件我注意到，HTML文件丟失：

如何指定我的POM fil e包含html文件？

我的POM現在是最小的：

<?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> 
    <version>1.0-SNAPSHOT</version> 
    <packaging>war</packaging> 

    <dependencies> 
     <dependency> 
      <groupId>org.apache.wicket</groupId> 
      <artifactId>wicket-core</artifactId> 
      <version>6.10.0</version> 
     </dependency> 
    </dependencies> 
</project> 

Answer 1

解決方案如果你想在你的類的最佳實踐場所中使用你的HTML，那就是將它添加到你的pom的構建部分。

<build> 
    <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> 
    </resources> 
</build> 
</project>

你應該把你HelloWorld.html文件到文件夾src/main/webapp。這樣它將被包含在war文件中
