Question

我试图在我的JAX-RS项目中添加一个名为ContainerRequestFilter的东西。首先，我创建了一个注释：

@NameBinding
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
public @interface IsAuthenticated {}

然后，我创建了提供者：

@PreMatching
@Provider
@IsAuthenticated
public class AuthenticationRequestFilter implements ContainerRequestFilter {

    public void filter(ContainerRequestContext requestContext) throws IOException {
        System.out.println("filter() on     ServerAuthenticationRequestFilter");
        Response.ResponseBuilder responseBuilder = Response.serverError();
        Response response = responseBuilder.status(Response.Status.BAD_REQUEST).build();
        requestContext.abortWith(response);
    }
}

然后，我在我的JAX-RS方法上使用它：

@GET
@Path("/trial")
@IsAuthenticated
public String trial() {
    return "Hello world";
}

不幸的是，这会因以下错误而崩溃：

StandardWrapperValve [SpringApplication]：Servlet的Servlet.service（） SpringApplication抛出了异常java.lang.NullPointerException org.glassfish.jersey.server.spring.scope.RequestContextFilter $ 2.resetAttributes（RequestContextFilter.java:125）在 org.glassfish.jersey.server.spring.scope.RequestContextFilter.filter（RequestContextFilter.java:138）在 org.glassfish.jersey.server.ContainerFilteringStage $ ResponseFilterStage.apply（ContainerFilteringStage.java:196）在 org.glassfish.jersey.server.ContainerFilteringStage $ ResponseFilterStage.apply（ContainerFilteringStage.java:163）在 org.glassfish.jersey.process.internal.Stages.process（Stages.java:171）在 org.glassfish.jersey.server.ServerRuntime $ Responder.processResponse（ServerRuntime.java:393）在 org.glassfish.jersey.server.ServerRuntime $ Responder.process（ServerRuntime.java:385）在 org.glassfish.jersey.server.ServerRuntime $ 1.run（ServerRuntime.java:280）在org.glassfish.jersey.internal.Errors $ 1.call（Errors.java:272）at at org.glassfish.jersey.internal.Errors $ 1.call（Errors.java:268）at org.glassfish.jersey.internal.Errors.process（Errors.java:316）at org.glassfish.jersey.internal.Errors.process（Errors.java:298）at org.glassfish.jersey.internal.Errors.process（Errors.java:268）at org.glassfish.jersey.process.internal.RequestScope.runInScope（RequestScope.java:289）在 org.glassfish.jersey.server.ServerRuntime.process（ServerRuntime.java:256）在 org.glassfish.jersey.server.ApplicationHandler.handle（ApplicationHandler.java:703）在 org.glassfish.jersey.servlet.WebComponent.serviceImpl（WebComponent.java:416）在 org.glassfish.jersey.servlet.WebComponent.service（WebComponent.java:370）在 org.glassfish.jersey.servlet.ServletContainer.service（ServletContainer.java:389）在 org.glassfish.jersey.servlet.ServletContainer.service（ServletContainer.java:342）在 org.glassfish.jersey.servlet.ServletContainer.service（ServletContainer.java:229）在 org.apache.catalina.core.StandardWrapper.service（StandardWrapper.java:1580）在 org.apache.catalina.core.StandardWrapperValve.invoke（StandardWrapperValve.java:258）在 org.apache.catalina.core.StandardContextValve.invoke（StandardContextValve.java:160）在 org.apache.catalina.core.StandardPipeline.doInvoke（StandardPipeline.java:652）在 org.apache.catalina.core.StandardPipeline.invoke（StandardPipeline.java:591）在com.sun.enterprise.web.WebPipeline.invoke（WebPipeline.java:99）at org.apache.catalina.core.StandardHostValve.invoke（StandardHostValve.java:155）在 org.apache.catalina.connector.CoyoteAdapter.doService（CoyoteAdapter.java:371）在 org.apache.catalina.connector.CoyoteAdapter.service（CoyoteAdapter.java:238）在 com.sun.enterprise.v3.services.impl.ContainerMapper $ HttpHandlerCallable.call（ContainerMapper.java:463）在 com.sun.enterprise.v3.services.impl.ContainerMapper.service（ContainerMapper.java:168）在 org.glassfish.grizzly.http.server.HttpHandler.runService（HttpHandler.java:206）在 org.glassfish.grizzly.http.server.HttpHandler.doHandle（HttpHandler.java:180）在 org.glassfish.grizzly.http.server.HttpServerFilter.handleRead（HttpServerFilter.java:242）在 org.glassfish.grizzly.filterchain.ExecutorResolver $ 9.execute（ExecutorResolver.java:119）在 org.glassfish.grizzly.filterchain.DefaultFilterChain.executeFilter（DefaultFilterChain.java:284）在 org.glassfish.grizzly.filterchain.DefaultFilterChain.executeChainPart（DefaultFilterChain.java:201）在 org.glassfish.grizzly.filterchain.DefaultFilterChain.execute（DefaultFilterChain.java:133）在 org.glassfish.grizzly.filterchain.DefaultFilterChain.process（DefaultFilterChain.java:112）在 org.glassfish.grizzly.ProcessorExecutor.execute（ProcessorExecutor.java:77）在 org.glassfish.grizzly.nio.transport.TCPNIOTransport.fireIOEvent（TCPNIOTransport.java:539）在 org.glassfish.grizzly.strategies.AbstractIOStrategy.fireIOEvent（AbstractIOStrategy.java:112）在 org.glassfish.grizzly.strategies.WorkerThreadIOStrategy.run0（WorkerThreadIOStrategy.java:117）在 org.glassfish.grizzly.strategies.WorkerThreadIOStrategy.access $ 100（WorkerThreadIOStrategy.java:56）在 org.glassfish.grizzly.strategies.WorkerThreadIOStrategy $ WorkerThreadRunnable.run（WorkerThreadIOStrategy.java:137）在 org.glassfish.grizzly.threadpool.AbstractThreadPool $ Worker.doWork（AbstractThreadPool.java:593）在 org.glassfish.grizzly.threadpool.AbstractThreadPool $ Worker.run（AbstractThreadPool.java:573）在java.lang.Thread.run（Thread.java:748）

但是，如果我从提供程序中删除以下行：

requestContext.abortWith(response);

然后崩溃消失（虽然这没有按预期工作，因为永远不会返回错误的请求）。我在web.xml上添加了：

<init-param>
    <param-name>jersey.config.server.provider.packages</param-name>
    <param-value>com.trial.filters</param-value>
</init-param>
<init-param>
    <param-name>jersey.config.server.provider.classnames</param-name>
    <param-value>com.trial.filters.AuthenticationRequestFilter</param-value>
</init-param>

发生了什么事？我做错了什么？

非常感谢

这个问题是由@PreMatching引起的，虽然我不知道为什么。但是，我已经删除了该注释，现在它正在按预期工作。

@NameBinding导致org.glassfish.jersey.server.spring.scope.RequestContextFilter $ 2.resetAttributes
