I'm trying to deploy an application containing a WebSocket endpoint on Wildfly and I get this error:

javax.websocket.DeploymentException: UT003012: Method public void Endpoint.openConnection(javax.websocket.Session,javax.websocket.EndpointConfig,java.lang.String) has invalid parameters [2]"}}

This is the code for the endpoint class:

import javax.websocket.EndpointConfig;
import javax.websocket.CloseReason;
import javax.websocket.OnClose;
import javax.websocket.OnOpen;
import javax.websocket.Session;
import javax.websocket.server.ServerEndpoint;
import javax.ws.rs.PathParam;

@ServerEndpoint(value = "/update-user/{token}")
public class UpdateUsersEndpoint {

    @OnOpen
    public void openConnection(Session session, EndpointConfig config, @PathParam("token") String token) {
        ...
    }

    @OnClose
    public void closedConnection(Session session, CloseReason reason, @PathParam("token") String token) {
        ...
    }
}

This is the full stack from Wildfly log:

The deployment is successful upon removing the two last parameters. Since the WebSocket JSR states that a method annotated with @OnOpen can have the parameters I have in my method, I can't understand why Wildfly refuses to deploy the application.

您正在使用 javax.ws.rs.PathParam 而不是 javax.websocket.server.PathParam。

我可能会向 Undertow 添加一个关于此的警告，这似乎是一种可能会发生很多的事情。

您的问题出在错误的库中，您的库中提供了服务器提供的 jar。这可能会导致各种注射问题。

如果您使用 maven 构建，那么<scope>provided</scope>您的依赖项中只会缺少一些。

对单个罐子的评论：

activation-1.1.1.jar <-- part of jdk, remove
apache-mime4j-0.6.jar 
asm-3.3.1.jar <-- probably not needed
commons-email-1.3.1.jar
commons-logging-1.1.1.jar <-- remove
geronimo-jta_1.1_spec-1.1.1.jar <-- remove this is JTA api jar, it is part of app server
gson-2.2.2.jar
istack-commons-runtime-2.16.jar
jackson-annotations-2.2.1.jar <-- using jackson directly in your app? if not remove jackson*
jackson-core-2.2.1.jar
jackson-databind-2.2.1.jar
jackson-jaxrs-base-2.2.1.jar
jackson-jaxrs-json-provider-2.2.1.jar
jackson-module-jaxb-annotations-2.2.1.jar
jaxb-api-2.2.7.jar <-- part of jdk and app server, remove
jaxb-core-2.2.7.jar <-- part of jdk and app server, remove
jaxb-impl-2.2.7.jar <-- part of jdk and app server, remove
jboss-annotations-api_1.2_spec-1.0.0.Final.jar <-- part of app server, should not be in deployment
jboss-ejb-api_3.2_spec-1.0.0.Final.jar <-- part of app server, should not be in deployment
jboss-interceptors-api_1.2_spec-1.0.0.Final.jar <-- part of app server, should not be in deployment
jboss-jms-api_2.0_spec-1.0.0.Final.jar <-- part of app server, should not be in deployment
jboss-servlet-api_3.1_spec-1.0.0.Final.jar <-- part of app server, should not be in deployment
jboss-websocket-api_1.0_spec-1.0.0.Final.jar <-- part of app server, should not be in deployment
jcl-over-slf4j-1.7.1.jar <-- probably not needed as wildfly overrides it
jsr173_api-1.0.jar <-- app server already provides that, could be removed
logback-classic-1.0.10.jar <-- are you server managed logging? if so remove
logback-core-1.0.10.jar <-- are you server managed logging? if so remove
mail-1.4.5.jar <-- part of app server
resteasy-client-3.0.6.Final.jar <-- client api in deployment? is your application client to some jaxrs services?
resteasy-jackson2-provider-3.0.6.Final.jar <-- remove
resteasy-jaxb-provider-3.0.6.Final.jar <-- remove
resteasy-multipart-provider-3.0.6.Final.jar <-- remove
slf4j-api-1.7.1.jar <-- are you server managed logging? if so remove

我认为您在这里拥有的大部分内容是因为您需要编译依赖项，但在运行时不需要它们。

另外，为什么您的应用程序中有两个 jaxrs 实现？这是故意的还是错误的？

这应该有效。您可以发布完整的端点定义吗？我能想到的只是你可能在客户端端点上使用它，这是行不通的。

我刚刚向 Undertow 添加了一个测试，它通过了，所以我不确定问题是什么：https ://github.com/undertow-io/undertow/commit/1be41d70ec5268e557cf0657638f0f77bc6d2f58
