Could not transfer artifact org.apache.tomcat.embed:tomcat-embed-core:jar:9.0.68 from/to central (https://repo.maven.apache.org/maven2): Transfer failed for https://repo.maven.apache.org/maven2/org/apache/tomcat/embed/tomcat-embed-core/9.0.68/tomcat-embed-core-9.0.68.jar
根据提供的引用内容,你遇到的问题是在下载jar包时出现了错误。具体来说,你无法从中央仓库(https://repo.maven.apache.org/maven2)成功下载org.apache.tomcat.embed:tomcat-embed-core:jar:9.0.68这个jar包。
解决这个问题的方法是检查你的网络连接是否正常,并确保你可以访问中央仓库。如果你的网络连接正常,但仍然无法下载该jar包,你可以尝试使用其他镜像仓库或者手动下载该jar包并将其添加到你的项目中。
另外,根据引用\[1\]提供的信息,你还需要下载其他三个jar包:tomcat-embed-el.jar(版本8.5.4),org.slf4j:slf4j-api.jar(版本1.7.21),jackson-core.jar(版本2.8.1)。你可以通过在百度或其他搜索引擎上搜索这些jar包的名称来找到它们的下载链接。
希望这些信息对你有帮助!

这个异常是java.io.EOFException,它表示在读取数据时到达文件末尾或连接关闭。根据堆栈跟踪,这个异常似乎是在Tomcat的WebSocket服务器端代码中引发的。它可能是由于客户端提前关闭了连接或者发送了不完整的数据导致的。
要解决这个问题,你可以检查以下几个方面:
1. 客户端代码:确保客户端在发送数据之后正确地关闭了连接。
2. 服务端代码:检查WebSocket服务器端代码是否正确处理了数据的读取和连接关闭的情况。
3. 网络连接:如果在使用WebSocket时遇到这个异常,可以检查网络连接是否稳定,并确保没有任何网络故障。
如果以上方面都没有问题,你可以尝试重现该异常并进一步调试,以确定异常发生的具体原因。
