我正在尝试使用wicket创建一个web应用程序。以下是我遵循的步骤:
> < li>
我使用以下命令创建了一个maven项目:
mvn原型:generate-DarchetypeGroupId=org.apache。wicket-DarchetypeArtifactId=wicket原型快速启动-DarchetypeVersion=6.6.0-DgroupId=com。mycompany-DartifactId=myproject-DarchetypeRepository=https://repository.apache.org/-DinteractiveMode=假
我导入了项目来日食
这是控制台上的错误消息:

任何人都可以帮我????
你换了你的POM吗?这个类属于< code>wicket-core,快速入门增加了这个:
<dependency>
<groupId>org.apache.wicket</groupId>
<artifactId>wicket-core</artifactId>
<version>6.6.0</version>
</dependency>

异常过滤器 With Nest you can move exception handling logic to special classes called Exception Filters. 你可以使用Nest将异常处理逻辑移动到异常过滤器的特殊类中。 How it works? 怎么运行呢? Let's take a look at the following code: 让我们来看看下面
