春季云数据流 - 无法从卡夫卡

转换邮件使用Spring云数据流的版本1.2.2具有以下配置：春季云数据流 - 无法从卡夫卡

spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.binders.kafka1.type=kafka 
spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.binders.kafka1.environment.spring.cloud.stream.kafka.binder.brokers=<MY_BROKER> 
spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.binders.kafka1.environment.spring.cloud.stream.kafka.binder.zkNodes=<MY_ZK>

我试图创建流将从特定主题阅读并刷新它到长片，如下：

stream create --name metricsStream --definition ":metrics --spring.cloud.stream.bindings.input.binder=kafka1 --spring.cloud.stream.bindings.output.content-type='text/plain;charset=UTF-8' > bridge | log" --deploy

展望上的日志文件，我可以看到以下错误：

2017-07-17 09:44:01,700 INFO -kafka-listener-1 log-sink:202 - [[email protected] 2017-07-17 09:44:01,700 ERROR -kafka-listener-1 o.s.c.s.b.k.KafkaMessageChannelBinder:283 - Could not convert message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java.lang.StringIndexOutOfBoundsException: String index out of range: 380

我也尝试配置为卡夫卡源

stream create --name metricsStream --definition ":metrics --spring.kafka.consumer.valueDerserializer=org.apache.kafka.common.serialization.StringDeserializer --spring.cloud.stream.bindings.input.binder=kafka1 --spring.cloud.stream.bindings.output.content-type='text/plain;charset=UTF-8' --spring.cloud.stream.bindings.input.consumer.headerMode=raw --spring.cloud.stream.bindings.output.producer.headerMode=raw --outputType='text/plain;charset=UTF-8' > bridge | log" --deploy

的消费者/生产者的某些属性，但我得到了相同的结果

这里是消费明细，由Spring数据流为印刷：

我看到了类似的quetion，但没有有效的答案 what is the property to accept binary json message in spring-cloud-stream kafka binder

我的卡夫卡指标主题包含JSON行。我应该如何配置Spring数据流能够从卡夫卡的JSON格式的主题阅读，看起来像JSON（或至少字符串格式？

您是否尝试过配置输入内容类型？

spring.cloud.stream.bindings.input.content-type=application/json

或许从春季云数据流的前缀：

spring.cloud.dataflow.applicationProperties.stream.spring.cloud.stream.binders.kafka1.environment.spring.cloud.stream.bindings.input.content-type=application/json

哎#codependent，有没有问过这个问题，不知何故别人登录到我的帐户，如果你有一定的，这是一个很好的答案，让我知道和我会接受它 –

我建议你改变你的密码......这就是我在简单的Striping Cloud Stream应用程序中配置反序列化的方式，所以它应该可以工作。 – codependent
