缺少Spring-cloud-stream-schema中的AvroSchemaMessageConverter类 - 1.2.0.RC1

Question

我在spring-cloud-stream-schema中缺少AvroSchemaMessageConverter类 - 1.2.0.RC1。我希望通过此链接Missing schema module for spring-cloud-stream。

  <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时，我预计课程AvroSchemaMessageConverter.java将在 spring-cloud-stream-1.2.0.RC1.jar 中提供。但它不存在，如下图所示：

有人可以指出我缺少的依赖关系。我的maven依赖关系spring-cloud-stream要发布到Kafka主题。

        <groupId>org.springframework.cloud</groupId>

    </dependencies>

Answer 1

它在架构jar中：

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

请注意该GitHub工件的完整层次结构......

spring-cloud-stream/spring-cloud-stream-schema/src/main/java/org/springframework/cloud/stream/schema/avro/AvroSchemaMessageConverter.java

Answer 2

您明确发布的链接提到您需要包含org.springframework.cloud:spring-cloud-stream-schema，其中AvroSchemaMessageConverter存在。您还需要明确添加Avro版本。
