有什么问题吗？如果有任何帮助，我将不胜感激。

编辑：

如果有帮助 - 我已经下载了刚刚部署在服务器上的示例 Web 项目，它运行良好。该项目具有上述依赖关系，但不同之处在于部署后的日志。部署该示例应用程序后，日志中是典型的 Spring 日志：

但在部署我的应用程序（附加依赖项）后，没有像上面这样的日志。只有应用程序已部署的信息。

【问题讨论】：

您可以尝试使用 postman 或 curl 向您的 API 发送请求，然后检查 cors 标头是否包含在响应中，如果没有，请尝试使用 cors 过滤器，您可以从这里stackoverflow.com/questions/51686029/…
@SannTran 当我尝试通过邮递员发送请求时，出现 404 错误。现在我真的很困惑..
这意味着您的 api 不工作。检查ip、端口、路径是否正确
@SannTran 更重要的是，如果我在 tomcat 停止 java 应用程序，错误是一样的。我不知道为什么它不起作用，因为写的是应用程序正在运行
