java - Wildfly 8，异步方法上 UriInfo 上下文的问题

Question

我在将一种方法转换为异步时遇到问题。我使用的是 wildfly 8.2.0，这个方法很好用:

@GET
@Path("externalCallback")
@Produces("text/html")
public Response authorize(@Context UriInfo uriInfo, @QueryParam(value =        
    "code") final String code,
    @QueryParam(value = "state") final String state) {

        URI baseUri = uriInfo.getBaseUri();
        final URI redirect = UriBuilder.fromUri(baseUri)
            .path("auth.html").build();        

        if (!validateAntiForgeryStateToken(state)) {
            throw new WebApplicationException("Invalid anti forgery state token");
        }

        return Response.seeOther(redirect).build();
    }

但如果我将其转换为异步，则失败并显示错误无法找到类型为 javax.ws.rs.core.UriInfo 的上下文数据

@GET
@Path("externalCallback")
@Produces("text/html")
@Asynchronous
public void authorize(@Suspended
final AsyncResponse asyncResponse, @Context
final UriInfo uriInfo, @QueryParam(value = "code")
final String code, @QueryParam(value = "state")
final String state) {

    asyncResponse.resume(doAuthorize(uriInfo, code, state));
}

private Response doAuthorize(@Context UriInfo uriInfo, @QueryParam(value = "code") final String code, @QueryParam(value = "state") final String state) {
    URI baseUri = uriInfo.getBaseUri();
    final URI redirect = UriBuilder.fromUri(baseUri)
            .path("auth.html").build();        

    if (!validateAntiForgeryStateToken(state)) {
        throw new WebApplicationException("Invalid anti forgery state token");
    }

    return Response.seeOther(redirect).build();
}

我尝试更改 doAuthorize 方法签名，将 UriInfo 更改为 URI，并传递授权中提取的值方法，但即使在这种情况下，它也会失败并出现相同的错误。

谁知道为什么会这样？它应该那样工作吗？

这是错误的完整调用堆栈(取自 wildfly 日志文件)

一旦您将其发送到异步模式，就没有与 UriInfo 关联的上下文。换句话说，需要从请求范围/上下文中访问 UriInfo。

解决它的唯一方法是在进入异步之前检索 URI。然后使用该 URI

进行处理

public void authorize(@Suspended AsyncResponse asyncResponse, 
                      @Context UriInfo uriInfo, 
                      @QueryParam(value = "code") String code,
                      @QueryParam(value = "state") String state) {

    URI uri = uriInfo.getBaseUri();
    asyncResponse.resume(doAuthorize(uri, code, state));
}
