Question

我正在尝试在Wildfly上部署包含WebSocket端点的应用程序，我收到此错误：

javax.websocket.DeploymentException：UT003012：方法public void Endpoint.openConnection（javax.websocket.Session，javax.websocket.EndpointConfig，java.lang.String中）有无效参数[2]“}}

这是端点类的代码：

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) {
        ...
    }
}

这是Wildfly日志的完整堆栈：

删除最后两个参数后，部署成功。由于WebSocket JSR表示使用@OnOpen注释的方法可以包含我在方法中使用的参数，因此我无法理解为什么Wildfly拒绝部署应用程序。

Answer 1

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

我可能会向Undertow添加一个警告，似乎可能会发生很多事情。

Answer 2

您的问题是在错误的lib中，您的lib是服务器中提供的jar。这可能会导致各种注射问题。

如果您使用maven构建，那么您的依赖项中只会遗漏少量<scope>provided</scope>。

对个别罐子的评论：

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-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-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

我认为你在这里的大部分内容都是因为你需要编译依赖项，但在运行时不需要它们。

另外，为什么你的应用程序中有两个jaxrs impls？是故意还是错误？

Answer 3

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

我刚刚给Undertow添加了一个测试，它传递得很好，所以我不确定问题是什么：https://github.com/undertow-io/undertow/commit/1be41d70ec5268e557cf0657638f0f77bc6d2f58
