打开网页，但无法连接到Websocket。

Question

• WebSocketConfig.java - https://pastebin.com/G4iUk5Q2
• ChatController.java - https://pastebin.com/TPxwxaKm
• ChatMessage.java - https://pastebin.com/qbfcSvTe
• MessageType.java - https://pastebin.com/kMA3MPGd
• index.html - https://pastebin.com/HBD6Tn6L
• main.js - https://pastebin.com/hn3m3p97

我正在使用localhost:8080连接，它生成“登录”页面，但是当我连接时，它会产生“无法连接到WebSocket服务器。请刷新此页面再试一次！”位于main.js第50行。

老实说，我对Spring和这一切都很陌生。我看了很多教程，试图找出为什么有些东西不起作用。它们都会产生同样的错误。我正在运行一个gradle应用程序，我将在下面提供我的build.gradle。我还将尝试显示我的完整控制台日志。

控制台日志- https://gist.github.com/beanbeanjuice/035f8dcd8e5b347eab87558fe713d8c8

会产生一些错误，例如LibraryNotFoundError for org.apache.tomcat.jni，然而，经过一些研究，这似乎是“正常”的行为。

第二个值得注意的错误是用于ClassNotFoundException的java.net.UnixDomainSocketAddress，它在切换到JDK 16时似乎消失了。然而，切换到JDK 16并没有解决这个问题。

这是我的build.grade；

我怀疑这与我的电脑有关，但此时我完全迷失了方向。

编辑1:似乎发生了什么事情，导致它得到一个404错误，即使它确实通过浏览器连接。websocket的登陆页面工作，但websocket本身不工作。这是错误；

我不知道404为什么会发生。我在做更多的研究，但是，我所尝试的一切还是不起作用。

Answer 1

我想通了。我的websocket包必须在相同的包中，或者在我的Main类的子包中。GG。
