通过eclipse插件启动我的应用程序时出现此异常:
“运行方式”>“使用 jetty 的 GWT 开发模式”
环境 :
- GWT SDK 2.8
- Spring 启动 1.5.2.RELEASE
- jetty 9.4.2
- GWT Eclipse 插件 3.0.0
上下文:将 GWT 2.6 应用程序迁移到 GWT 2.8 并使用 spring-boot
使用 GWT webAppCreator 生成的应用程序 pom
这是堆栈跟踪 :

我做了另一个测试 : 我删除了 spring-boot 依赖:result=same exception。此外，依赖树显示了版本 9.2.14.v20151106 中的所有 jetty 属性
此外，我尝试搜索类
org.eclipse.jetty.websocket.server.WebSocketServerFactory在 jar 里，但没有找到。它现在在哪里？为什么在日志中提到了这个类？
感谢您的帮助
请您参考如下方法:
您在类路径上有多种 Jetty 版本:9.4.2.v20170220 和 9.2.14.v20151106。前者是 Spring Boot 1.5.2 默认使用的。我猜后者来自 com.google.gwt:gwt 的导入。 .
您可以覆盖 jetty.version Spring Boot 用于将其值设置为 9.2.14.v20151106 的属性，从而在任何地方都使用 9.2.14。或者，您可以为当前使用 9.2.14 的模块声明自己的依赖项管理，以将它们升级到 9.4.2。
