EventStoreDB Java客户端appendToStream阻塞无返回问题及解决

问题现象 #

试用EventStoreDB时，调用client.appendToStream()方法出现阻塞，且该方法永不返回，后续代码无法执行。

环境配置 #

EventStoreDB Docker启动命令 #

docker run --name esdb-node -it -p 2113:2113 -p 1113:1113 eventstore/eventstore:latest --insecure --run-projections=All --enable-atom-pub-over-http

初始使用的Maven依赖 #

<dependency>
    <groupId>com.eventstore</groupId>
    <artifactId>db-client-java</artifactId>
    <version>5.3.1</version>
</dependency>

测试代码 #

EventStoreDBClientSettings setts =
        EventStoreDBConnectionString.parseOrThrow("esdb://localhost:2113?tls=false&tlsVerifyCert=false");
EventStoreDBClient client = EventStoreDBClient.create(setts);

AccountCreated event = new AccountCreated();
JsonMapper jsonMapper = new JsonMapper();
event.setId(UUID.randomUUID().toString());
event.setLogin("test");

EventData eventData = EventData
        .builderAsJson("AccountCreated", jsonMapper.writeValueAsBytes(event))
        .build();

client.appendToStream("some-stream", eventData)
        .get();

System.out.println("This never happens");

解决方案 #

将Maven依赖中db-client-java的版本降级至5.2.0后，问题解决。
