我在我的objectmapperbuilder配置中配置了mixins,使用常规弹簧Web控制器,根据mixins输出数据.但是,使用webflux,具有返回Flow或Mono的方法的控制器将数据序列化,就像objectmapper是默认数据一样.

如何让webflux强制执行objectmapper配置？

示例配置:

@Bean
JavaTimeModule javatimeModule(){
    return new JavaTimeModule();
}

@Bean
Jackson2ObjectMapperBuilderCustomizer jackson2ObjectMapperBuilderCustomizer(){
return jacksonObjectMapperBuilder ->  jacksonObjectMapperBuilder.featuresToEnable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS)
                                                                    .mixIn(MyClass.class, MyClassMixin.class);
}

我正在尝试使用 gcloud beta 模拟器中的 bigtable 模拟器。我启动模拟器，获取主机名（localhost）和端口（在本例中为 8885）

gcloud beta 模拟器 bigtable start

执行：/usr/local/Caskroom/google-cloud-sdk/latest/google-cloud-sdk/platform/bigtable-emulator/cbtemulator --host=localhost --port=8885

我正在尝试从 java 测试客户端连接到模拟器，这是我提供的：

Configuration conf = BigtableConfiguration.configure(projectId, instanceId);

if(!Strings.isNullOrEmpty(host)){
    conf.set(BigtableOptionsFactory.BIGTABLE_HOST_KEY, host);
    conf.set(BigtableOptionsFactory.BIGTABLE_PORT_KEY, Integer.toString(port));
}
connection = BigtableConfiguration.connect(configuration);
try (Table table = connection.getTable("tName")){
    table.put(<Put instance>);
} 

当我执行测试代码时，我得到：

16:36:37.369 [bigtable-batch-pool-1] INFO com.google.cloud.bigtable.grpc.async.AbstractRetryingRpcListener - Retrying failed call. Failure #1, got: Status{code=UNAVAILABLE, description=null, cause=java.net.ConnectException: Connection refused: localhost/0:0:0:0:0:0:0:1:8885}
java.net.ConnectException: Connection refused: localhost/0:0:0:0:0:0:0:1:8885

我正在使用图书馆： com.google.cloud.bigtable:bigtable-hbase-1.2:0.9.1

知道我做错了什么吗？

谢谢 ！

我试图了解我对云存储性能的期望。我刚刚从与我的云存储桶位于同一位置（美国）和同一项目的计算引擎实例运行了 gsutil perfdiag。

对于近线存储，我的读取速度为 25 Mibit/s，写入速度为 353 Mibit/s，这是低/高/平均值，为什么读取和写入之间存在这种差异？
