Question

当我尝试使用Probruf反序列化protobuf时遇到问题
ProtobufIOUtil.mergeFrom（decodedString，TSchemaObject，tsschema）;

here is my .proto file

syntax = "proto2";
option java_package = "com.xyzschema";
option java_outer_classname = "TSchema";

message TS {
    optional ts ts = 2;
}

message ts {
    optional Events Events = 1;
    repeated string flight_time = 2;
    optional string view_id = 3;
}


message Events {
    optional bool x = 1;
    optional bool y = 2;

}

repeated string flight_time = 2; is the one giving problems

我使用此将JSON转换为pb byte []数据=
ProtobufIOUtil.toByteArray（ts.build（），schema，buffer）;

但是一旦我将其转换，我想从字节中取回pb []

    ProtobufIOUtil.mergeFrom(data, TSObject, tsschema);

I am using the following dependencies
