ContainerRequestFilter在我的Quarkus扩展中被忽略了

Question

我想实现一个要在我的服务中使用的自定义扩展。其中一个关键特性是过滤所有传入请求：

@Provider
public class RequestInterceptor implements ContainerRequestFilter {

    private static final Logger logger = Logger.getLogger(RequestInterceptor.class.getName());

    @Override
    public void filter(ContainerRequestContext requestContext) {
        logger.info("Testing extension interceptor");
    }
}

它是以这种方式宣布的：

class LoggingExtensionProcessor {

    private static final Logger logger = Logger.getLogger(LoggingExtensionProcessor.class.getName());

    private static final String FEATURE = "logging-extension";

    @BuildStep
    FeatureBuildItem feature() {
        return new FeatureBuildItem(FEATURE);
    }

    @BuildStep
    ServletBuildItem createServlet() {
        logger.info("createServlet");
        return ServletBuildItem.builder(FEATURE, GreetingExtensionServlet.class.getName())
                .addMapping("/greeting")
                .build();
    }

    @BuildStep
    AdditionalBeanBuildItem registerAdditionalBeans() {
        logger.info("registerAdditionalBeans");
        return AdditionalBeanBuildItem.builder()
                .setUnremovable()
                .addBeanClass(RequestInterceptor.class)
                .build();

    }

    @BuildStep
    ResteasyJaxrsProviderBuildItem registerConfiguration() {
        logger.info("registerConfiguration");
        return new ResteasyJaxrsProviderBuildItem(RequestInterceptor.class.getName());
    }
}

我还尝试在运行时pom中添加Jandex插件。

            <plugin>
                <groupId>org.jboss.jandex</groupId>
                <artifactId>jandex-maven-plugin</artifactId>
                <version>1.2.2</version>
                <executions>
                    <execution>
                        <id>make-index</id>
                        <goals>
                            <goal>jandex</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>

但没人叫它。

我看到了一个类似的场景here，但是这个解决方案对我不起作用。

有什么建议吗？提前谢谢。

最后，我找到了解决办法。

我使用的是提供quarkus-resteasy-reactive-jackson的@ServerRequestFilter库，您可以构建一个CustomContainerRequestFilterBuildItem，用于注册使用@ServerRequestFilter注释的类。

public class RequestInterceptor {

    private static final Logger logger = Logger.getLogger(RequestInterceptor.class.getName());

    @ServerRequestFilter(preMatching = true)
    public void filter(ContainerRequestContext requestContext) {
        logger.info("Testing extension interceptor");
    }
}

class LoggingExtensionProcessor {

    private static final Logger logger = Logger.getLogger(LoggingExtensionProcessor.class.getName());

    private static final String FEATURE = "logging-extension";

    @BuildStep
    FeatureBuildItem feature() {
        return new FeatureBuildItem(FEATURE);
    }

    @BuildStep
    ServletBuildItem createServlet() {
        logger.info("createServlet");
        return ServletBuildItem.builder(FEATURE, GreetingExtensionServlet.class.getName())
                .addMapping("/greeting")
                .build();
    }

    @BuildStep
    CustomContainerRequestFilterBuildItem buildContainerRequestFilter() {
        return new CustomContainerRequestFilterBuildItem(RequestInterceptor.class.getName());
    }
}
