问题描述
当通过eclipse插件启动我的应用程序时，我有这个异常：
Run as>使用jetty的GWT开发模式
环境：
- GWT SDK 2.8
- spring-boot 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GWT生成的spring-boot
应用程序pom webAppCreator
以下是堆栈跟踪：

为什么我的应用程序无法启动？
这是我的pom和依赖关系树。

我做了其他测试：我删除了spring -boot依赖项：结果=相同的异常。此外，依赖关系树显示了版本9.2.14.v20151106中的所有jetty atrifacts
此外，我尝试搜索类 org.eclipse.jetty .websocket.server.WebSocketServerFactory 在jar中但未找到。它在哪里？为什么这个类被记录在日志中？
感谢您的帮助
解决方案
类路径上的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。我猜想后者是从 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，从而使用9.2.14到处。或者，您可以为当前使用9.2.14的模块声明您自己的依赖项管理，以将其升级到9.4.2。

I did an other test: I delete spring-boot dependency: result=same exception. Moreover, the dependency tree shows all jetty atrifacts in version 9.2.14.v20151106
Moreover, I try to search the class org.eclipse.jetty.websocket.server.WebSocketServerFactory in jars but not found. Where is it present? Why this class is mentionned in logs?
Thank you for your help
解决方案
You have a mixture of Jetty versions on the class path: 9.4.2.v20170220 and 9.2.14.v20151106. The former is what Spring Boot 1.5.2 uses by default. I would guess that latter is from the import of com.google.gwt:gwt.
You could override the jetty.version property that Spring Boot uses to set its value to 9.2.14.v20151106, thereby using 9.2.14 everywhere. Alternatively, you could declare your own dependency management for the modules that are currently using 9.2.14 to upgrade them to 9.4.2.
这篇关于NoSuchMethodError：org.eclipse.jetty.websocket.server.WebSocketServerFactory。< init>（Ljavax / servlet / ServletContext;）V的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
