如何在quarkus框架中使用@ServerRequestFilter，该框架使用vert.x读取ContainerRequestContext中的请求正文

Question

我想在@ServerRequestFilter过滤器中打印post请求正文的json日志

    @ServerRequestFilter
public void requestFilter(ContainerRequestContext requestContext) throws IOException {
    InputStream entityStream = requestContext.getEntityStream();
    byte[] data = new byte[1024];
    int r;
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    while ((r = entityStream.read(data)) > 0) {
        out.write(data, 0, r);
    }
    log.info(StrUtil.format("body->[{}]", out.toString(StandardCharsets.UTF_8)));
    requestContext.setEntityStream(new ByteArrayInputStream(out.toByteArray()));
}

但是我发现无论我对entityStream触发器做什么：

java.io.IOException: Attempting a blocking read on io thread
   at org.jboss.resteasy.reactive.server.vertx.VertxInputStream$VertxBlockingInput.readBlocking

如果您真的想这样做，您应该在扩展javax.ws.rs.core.application的类上添加@blocking，如下所示：

@Blocking 
public class MyApplication extends Application {
}
