Error while running HelloActivity Sample Temporal Java program
问题
我运行 Temporal 的 HelloActivity Java 示例时遇到以下错误：
06:43:55.969 [main] INFO io.temporal.internal.worker.Poller - start(): Poller{options=PollerOptions{maximumPollRateIntervalMilliseconds=1000, maximumPollRatePerSecond=0.0, pollBackoffCoefficient=2.0, pollBackoffInitialInterval=PT0.1S, pollBackoffMaximumInterval=PT1M, pollThreadCount=5, pollThreadNamePrefix='Host Local Workflow Poller'}, identity=23af0cb3-09aa-4cbc-bca2-118cfa79dc96}

作为先决条件，我已经执行了 docker-compose up，并且我正在运行三个服务：temporalio/web、temporalio/auto-setup 和 cassandra。

As pre-requisite, docker-compose up was executed and I have all 3 services temporalio/web, temporalio/auto-setup, and cassandra running.

确保你正在运行与示例所需的Java SDK相同版本的服务。
看起来示例的README没有更新到最新版本。截止到现在（2020年7月21日），v0.27.0是最新版本。因此，先关闭当前正在运行的服务：
docker-compose down
然后安装最新版本：
curl -L https://github.com/temporalio/temporal/releases/download/v0.27.0/docker.tar.gz | tar -xz --strip-components 1 docker/docker-compose.yml
docker-compose up
英文:
Make sure that you are running the same version of the service as the Java SDK used by the samples requires.
It looks like the Samples README wasn't updated with the latest version. As of now (7/21/20) the v0.27.0 is the latest version. So tear down the currently running version of the service:
docker-compose down
then install the latest one:
curl -L https://github.com/temporalio/temporal/releases/download/v0.27.0/docker.tar.gz | tar -xz --strip-components 1 docker/docker-compose.yml
docker-compose up
