我有一个简单的资源,它返回一个 Uni<Response>

@POST
@Path("/test2")
public Uni<Response> test2(SampleEntity test) {
    List<SampleEntity> recordList = new ArrayList<>();
    recordList.add(new SampleEntity("cat", 12));
    recordList.add(new SampleEntity("dog", 14));
    return Uni.createFrom().item(Response.ok(recordList).build());
}

我有一个示例拦截器,用于将请求/响应记录为 json

    @AroundInvoke
public Object resourceLog(InvocationContext context) throws Exception {
    timer.restart();
    log.info(StrUtil.format("request->[{}]", JSONUtil.toJsonStr(context.getParameters())));
    Object response = context.proceed();
    log.info(StrUtil.format("response->[{}]", response));
    return response;
}

当我发送 json 请求时:

{
"name": "cat",
"age": 12
}

打印出来的日志是:

2021-04-09 10:29:34,529 INFO  [cof.gei.int.ResourceInterceptor] (vert.x-eventloop-thread-4) request->[[{"name":"cat","age":12}]]
2021-04-09 10:29:34,529 INFO  [cof.gei.int.ResourceInterceptor] (vert.x-eventloop-thread-4) response->[io.smallrye.mutiny.operators.uni.builders.UniCreateFromKnownItem@a0122dd]

我想问的问题是: 拦截器拦截到一个Uni<Response>的响应时,如何打印出响应的json内容

这是我目前的解决方案:

        Object response = context.proceed();
    if(response instanceof Uni uni) {
        uni.subscribe().with(body -> log.info(StrUtil.format("response->Uni:[{}]", JSONUtil.toJsonStr(body))));
    }else {
        log.info(StrUtil.format("response->[{}]", JSONUtil.toJsonStr(response)));
    }

但我认为它很丑。

最好的方法是不使用 CDI 拦截器,而是使用 JAX-RS ContainerResponseFilter

它看起来像:

@Provider
public class YourFilter implements ContainerResponseFilter {

    @Override
    public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext)
            throws IOException {
        Object entity = responseContext.getEntity(); // this will contain the body of the response
        // print it
    }
}
