命名空间错误的 ProtoBuf 模式
ProtoBuf schema having wrong namespace
我已经这样定义了我的 Protobuf 模式
message VertexUpdate {
required VertexId id = 1;
map<string, google.protobuf.Value> properties = 2;
optional bool isDelete = 3;
}
message EdgeUpdate {
required EdgeId id = 1;
map<string, google.protobuf.Value> properties = 2;
optional bool isDelete = 3;
}
message GraphUpdate {
required string graphName = 1;
optional VertexUpdate vertexUpdate = 2;
optional EdgeUpdate edgeUpdate = 3;
}
我正在执行这段代码
Graphaction.GraphUpdate graphUpdate = createGraphUpdateObject();
Schema schema = ProtobufData.get().getSchema(Graphaction.GraphUpdate.class);
ProtobufData.get().newRecord(graphUpdate, schema);
这给我错误

我不知道为什么 class 名称在架构对象中提到为“com.mycompany.protos.kgschema.Graphaction_.GraphUpdate”,我认为这是此问题的根本原因。
确认我尝试了这段代码(尝试使用正确的 class 名称导致异常的方法调用)
Class<?> out =
org.apache.avro.util.ClassUtils.forName("com.mycompany.protos.kgschema.Graphaction$GraphUpdate");
并且它工作正常,没有任何错误。
我不明白为什么 class 名称空间在创建的模式对象中出错
ProtobufData.get().getSchema(Graphaction.GraphUpdate.class)
还有什么办法可以解决?感谢任何帮助。
我发现这是 Avro-protobuf 1.8 版的问题,并在 1.9 版以后得到修复
