Missing schema module for spring-cloud-stream

问题

Trying to use the following example from Spring Docs

@Bean
public MessageConverter userMessageConverter() throws IOException {
  AvroSchemaMessageConverter avroSchemaMessageConverter {
  return new AvroSchemaMessageConverter(MimeType.valueOf("avro/bytes");
}

Using Gradle as follows

buildscript {
  ext {
    springBootVersion = '1.4.2.RELEASE'
  }
  dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
  }
}

apply plugin: 'org.springframework.boot'

dependencies {
  compile('org.springframework.cloud:spring-cloud-stream')
  compile('org.springframework.cloud:spring-cloud-starter-stream-kafka')
}

dependencyManagement {
  imports {
    mavenBom "org.springframework.cloud:spring-cloud-dependencies:Camden.SR2"
  }
}

Gradle is loading the correct version of spring-cloud-streams 1.1.0.RELEASE but it does not match with the Github Repo. The artifact is missing the org.springframework.cloud.stream.schema package/source.

Am I missing something here?

回答1:

The artifact org.springframework.cloud:spring-cloud-starter-stream-kafka brings in spring-cloud-stream, spring-cloud-stream-codec and related dependencies like spring-integration. You would have to explicitly define org.springframework.cloud:spring-cloud-stream-schema.

Also, you don't need to specify 'org.springframework.cloud:spring-cloud-stream' as it will be part of org.springframework.cloud:spring-cloud-starter-stream-kafka via org.springframework.cloud:spring-cloud-stream-binder-kafka.
