spring-cloud-stream-schema - 1.2.0.RC1 中缺少 AvroSchemaMessageConverter class

Question

我在 spring-cloud-stream-schema - 1.2.0.RC1 中缺少 AvroSchemaMessageConverter class。我要通过这个link。

  <dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-stream-schema</artifactId>
    <version>1.2.0.RC1</version>
  </dependency>

当我查看 pom.xml, I was anticipating the class AvroSchemaMessageConverter.java 时将在 spring-cloud-stream-1.2.0.RC1.jar 中可用。但是如下图所示不存在:

有人可以指出我缺少的依赖关系。 我对 spring-cloud-stream 的 Maven 依赖关系到 post 到 Kafka 主题。

Answer 1

您发布的 link 明确提到您需要包含 org.springframework.cloud:spring-cloud-stream-schema，AvroSchemaMessageConverter 所在的位置。您还需要明确添加 Avro 版本。

Answer 2

它在架构 jar 中：

<!-- Apache avro serialization support  -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-stream-schema</artifactId>
</dependency>
