需要带Vertx日志说明的GRPC

grpc-java vert.x grpc kotlin

Maddy · 技术社区 · 6 年前

我使用Kotlin实现了一个带有Vertx的GRPC API,并为调试启用了最好的日志级别。在我的集成测试中,我尝试使用通道将GRPC客户机连接到服务器。

客户端代码段:

    val clientAsync1 = ctx.async()
            val channel1 = VertxChannelBuilder
                    .forAddress(vertx, "localhost", 10000)
                    .usePlaintext(true)
                    .build()
            val stub1 = ExampleGrpc.newVertxStub(channel1)

            val request = builderUtil.buildRequest()

            stub1.attemptFriendship(request) { stream ->
                    stream.handler { response ->

                    }
            }

我在GRPC Verticle的日志中看到了以下内容:

    [main] 2018-05-24T12:42:27.69+09:00 FINE [io.grpc.internal.ManagedChannelImpl]  [{0}] Exiting idle mode

    [vert.x-eventloop-thread-0] 2018-05-24T12:42:46.81+09:00 FINE [io.grpc.internal.ManagedChannelImpl]  [{0}] Shutting down

有人能解释一下怎么做吗 [{0}]{1}{2} 意思是?请注意,有几个通道是为完成测试而创建的,响应是流。

这个 {0} 格式为 MessageFormat 哪个是默认的格式化程序 java.util.logging . 当调用类似 log(Level level, String msg, Object[] params) , the params 应该和 msg 以形成日志字符串。这是有益的,因为如果不打印日志,则可以避免处理。

如图所示 java.util.logging.Logger 文档:

通常,格式化程序使用java.text.messageformat样式格式化来格式化参数,因此,例如格式字符串“0 1”将两个参数格式化为字符串。

这个 java.util.logging.Formatter 但在您的环境中配置的似乎并没有这样做。
