Jakarta ee grails 3.0.9 WebSocket 404错误

我正在尝试用grails创建聊天应用程序。我正在使用Grails3.0.9和tomcat-8.0.28

对不起，重复了

我读了这个，然后。。。但这并不能解决我的问题

我已经将javax.websocket-api更改为如下所示：

provided 'javax.websocket:javax.websocket-api:1.0'

但我仍然得到这个错误：

Firefox

：Firefox无法建立与位于“”的服务器的连接

Chrome

：WebSocket握手时出错：意外响应代码：404

你可以看到这个

这是我的密码

===================================================================

我尝试运行：grails prod run应用程序

我的websocket无法工作

但如果我运行grails run应用程序，它就会工作

这是因为我把

ServerEndPointDemo.groovy

放在

/src/main/groovy/com.akiong/ServerEndPointDemo.groovy

==============================================================================

如果（Environment.current==Environment.DEVELOPMENT）

我认为它应该在您当前的grails下工作……只需在app文件夹中运行一个grails应用程序（我还没有尝试过）。还有serverContainer.addEndpoint（WsChatEndpoint）这是在开发模式下对grails 2的一次攻击。也许你可以尝试将其添加到当前的端点，并在其周围不包装任何环境，看看它是否有影响。我将不得不在家中尝试测试项目，直到明天才能看到它是否工作。我尝试使用grails 3.0.9运行……但我得到了这个错误。|错误失败d编译stop-app.groovy:启动失败：stop-app.groovy:60:无法解析GroovyMBean@line 60，第18列。def mbean=new GroovyMBean（服务器，objectName）^然后我下载graisl 3.0.1来运行它..但仍然可以得到它error@vahid您好……我从grails.slack.com

：这可能不是您的问题，但我们在部署支持websocket的应用程序时遇到了一些问题（grails 3.0.9，Tomcat 7）原因很简单，websocket连接被配置为在根上下文上连接。这在grails run app下工作，因为该应用以localhost:[port]/运行，但在Tomcat上失败，因为该应用部署为服务器：[port]/[​*appname*​]/（编辑）​[9:11]我们刚刚更改了tomcat配置，将WAR文件部署到根上下文中，现在可以正常工作了。注释不用于扩展讨论；此对话已完成。
