在RESTEasy Reactive/Quarkus中插入HttpRequest失败

Question

我目前正在尝试在Quarkus 1.13中注入和读出HttpRequest，但是没有任何成功。我使用RESTEasy-Reactive作为我的endpoint。

这就是我目前包含它的方式。

@Path("/users/{id}")
class UserController(
    @Inject val service: UserService,
    @Context val httpRequest: io.vertx.core.http.HttpServerRequest,
) 
...

构建过程成功，但是当我试图访问像< code > http request . absolute uri()这样的属性时，我得到了一个NPE

java.lang.NullPointerException: Cannot invoke "org.jboss.resteasy.reactive.server.core.ResteasyReactiveRequestContext.serverRequest()" because the return value of "org.jboss.resteasy.reactive.server.core.CurrentRequestManager.get()" is null
    at io.quarkus.resteasy.reactive.server.runtime.QuarkusContextProducers.httpServerRequest(QuarkusContextProducers.java:26)
    at io.quarkus.resteasy.reactive.server.runtime.QuarkusContextProducers_Subclass.httpServerRequest$$superaccessor3(QuarkusContextProducers_Subclass.zig:451)
    at io.quarkus.resteasy.reactive.server.runtime.QuarkusContextProducers_Subclass$$function$$3.apply(QuarkusContextProducers_Subclass$$function$$3.zig:29)
    ...

我还尝试了其他类，如io.vertx.mutiny.core.http.HttpServerRequest或java.net.http.HttpRequest，但仍然没有成功。用@Inject注入它甚至没有构建。我缺少HttpServletRequest类：/

有人有主意吗？

你有几个选择：

使用HttpFilter：https://javaee.github.io/javaee-spec/javadocs/javax/servlet/http/HttpFilter.html

@WebFilter(urlPatterns = "/*")
public class FilterEverything extends HttpFilter {


    @Override
    protected void doFilter(HttpServletRequest req, HttpServletResponse res, FilterChain chain) throws IOException, ServletException {

        //Do something with HttpServletRequest 
    }

}

使用container request filter:https://docs . Oracle . com/javaee/7/API/javax/ws/RS/container/container request filter . html

作为Quarkus文档展示：

@Provider
public class LoggingFilter implements ContainerRequestFilter {

    private static final Logger LOG = Logger.getLogger(LoggingFilter.class);

    @Context
    UriInfo info;

    @Context
    HttpServerRequest request;

    @Override
    public void filter(ContainerRequestContext context) {

        //Do whatever you want
    }
}

作为方法签名的一部分：

@GET
@Path("/someEndPoint")
@Produces("application/json")
public JsonObject getData(@PathParam("owner") String owner, @Context HttpServletRequest request) {
   //Do something here
}
