我正在运行 hello world 示例

但是，我使用的是2.7版本。

However, I am using version 2.7.

在maven pom.xml我有

我尝试从命令行运行servlet，并在Eclipse上使用Server插件。我得到相同的错误：

I tried running the servlet from command line and from withing the Server plugin on Eclipse. I get the same error:

奇怪的是我可以看到.jar文件中的类。课程就在那里。

The weird thing is that I can see the class among the .jar files. The class is there.

我甚至尝试添加跳过maven的jar，但Tomcat不会看到该类。

I have even tried adding the jar skipping maven, but Tomcat won't see the class.

推荐答案

从

Eclipse + tomcat - 部署时的ClassNotFound异常

如果您已经同时安装Maven Eclipse插件和Maven WTP插件这是自动的。如果您没有安装它们，请继续安装它们，然后一旦Eclipse重新启动右键单击项目并执行Maven> Update项目....这将在内部更改项目配置，以便将Maven依赖项复制到您的部署目标上的/ WEB-INF / lib文件夹。

If you have installed both the Maven Eclipse Plugin and the Maven WTP Plugin this is automatic. If you don't have these installed, go ahead and install them and then once Eclipse restarts right-click on the project and do a Maven > Update project.... This will internally change the project configuration so the Maven dependencies are copied to the /WEB-INF/lib folder on your deployment target.

如果您不想使用任何这些插件，那么您必须转到项目属性>部署程序集配置并手动添加依赖项，但是这又是由这些插件自动完成的。

If you don't want to use any of these plug-ins, then you have to go to the Project properties > Deployment Assembly configuration and add your dependencies manually, but again, this is done automatically by these plug-ins.
