Java Apache Avro未生成UUID

无论我尝试了什么，Avro都不会在代码中为字段生成UUID类

版本：1.8.2和1.9.1

我尝试使用以下模式生成UUID：

  "type": "record",
  "name": "RecordWithUUID",
  "namespace": "avro",
  "fields": [
    {
      "name": "uuid",
      "type": {
        "type": "string",
        "logicalType": "uuid"
      }
    }
  ]
}

这是来自Avro项目测试类的类

TestReflectLogicalTypes

：

RecordWithUUID

简言之，这是Avro用来测试其代码功能的模式示例，我希望它能正常工作

我这样运行是为了从我的方案中获取java代码：

java-jar avro-tools-1.8.2.jar编译模式my_scheme.avsc.

java-jar avro-tools-1.9.1.jar编译模式my_scheme.avsc.

Avro的初始类代码如下所示：

class RecordWithUUID {
  UUID uuid; // <- UUID (!!!)

  @Override
  public int hashCode() {
    return uuid.hashCode();
  }

  @Override
  public boolean equals(Object obj) {
    if (obj == null) {
      return false;
    }
    if (!(obj instanceof RecordWithUUID)) {
      return false;
    }
    RecordWithUUID that = (RecordWithUUID) obj;
    return this.uuid.equals(that.uuid);
  }
}

class RecordWithUUID{
UUID UUID；//试试1.10.0-SNAPSHOT，我让它在那里工作（在经历了与其他版本相同的问题之后）
1.10.2中也一样。也许OP和其他人缺少一些东西。
