我的应用程序需要Websockets进行实时更新。所以我找到了这个例子并且一步一步做了。
我搜索了很多，但我没有找到解决方案。
我希望任何人都可以提前帮助我。
祝好，帕特里克 解决方案
通过添加以下maven依赖项：
<依赖项>
< groupId> org.apache.tomcat.embed< / groupId>
< artifactId> tomcat-embed-websocket< / artifactId>
< version> 7.0.52< / version>
< /依赖关系>
正如Craig Otis指出的那样，如果您计划部署到Tomcat，您应该使用< scope> test< / scope> ，以确保您不会在构建工件中包含依赖项。
I need Websockets for real-time updates in my application. So i found this example and did it step by step here. I went through the tutorial and finally i got this exception when starting the application:
I have searched a lot, but i didn't find a solution.
I hope anyone can help me, thanks in advance.
best regards, patrick
I managed to resolve this issue by adding the following maven dependency:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-websocket</artifactId>
<version>7.0.52</version>
</dependency>
As pointed by Craig Otis, if you're planning on deploying to Tomcat anyway, you should use <scope>test</scope> to ensure you don't include the dependency in your build artifact.
