spring-boot - WildFly 14：org.apache.tomcat.websocket.server.WsServerContainer 类无法转换为 io.undertow.websockets.jsr.ServerWebSocketContainer 类

Question

尝试将 Spring Boot 应用程序部署到 WildFly 14 我收到以下错误：

server.WsServerContainer 位于加载程序“deployment.application_name.war”@56a6a8b7 的未命名模块中；io.undertow.websockets.jsr.ServerWebSocketContainer 位于加载程序 '[e-mail]' @59ba0563 的未命名模块中）由：java.lang.ClassCastException：类 org.apache.tomcat.websocket.server .WsServerContainer 无法转换为 io.undertow.websockets.jsr.ServerWebSocketContainer 类（org.apache.tomcat.websocket.server.WsServerContainer 位于加载程序“deployment.application_name.war”@56a6a8b7 的未命名模块中；io.undertow.websockets。 jsr.ServerWebSocketContainer 位于加载程序 '[e-mail]' @59ba0563)"}} 的未命名模块中

我已经尝试了在 stackoverflow 或其他博客、论坛等中可以找到的所有内容，但没有运气。我最终得到了以下 pom.xml。

有人可以检查我的 pom.xml 并告诉我缺少什么吗？

Answer 1

您必须将 spring-boot-starter-underow 设置为 scope = provided。这适用于任何其他 Web 服务器。
