Question

我正在尝试在Thrift中序列化C联合，然后在Java中反序列化。在Java方面，我总是只序列化第一个联合字段。可能是某个人面临类似的问题？

节俭0.9.3

messages.thrift：

struct JLException {
...
}

struct JLFrame {
...
}

union JLMessage {
    1: JLException exc,
    2: JLFrame frame
}

C中的序列化代码（我替换为“......”不必要的部分）：

JLException* jlExeption = g_object_new(TYPE_J_L_EXCEPTION, ... , NULL);

if (jlExeption) {
    JLMessage* jlMessage = g_object_new(TYPE_J_L_MESSAGE, "exc", jlExeption, NULL);

    serialize_and_send_thrift_message((ThriftStruct*) jlMessage,
        THRIFT_STRUCT_CLASS(J_L_MESSAGE_GET_CLASS(jlMessage)));

    g_object_unref(jlExeption);
    g_object_unref(jlMessage);
}

JLFrame* jlFrame = g_object_new(TYPE_J_L_FRAME, ... , NULL);

if (jlFrame) {
    JLMessage* jlMessage = g_object_new(TYPE_J_L_MESSAGE, "frame", jlFrame,
        NULL);

    serialize_and_send_thrift_message((ThriftStruct*) jlMessage,
        THRIFT_STRUCT_CLASS(J_L_MESSAGE_GET_CLASS(jlMessage)));

    g_object_unref(jlFrame);
    g_object_unref(jlMessage);
}

Java中的反序列化代码：

TDeserializer deserializer = new TDeserializer();
JLMessage message = new JLMessage();

try {
    byte[] binData = tuple.getBinary(0);
    deserializer.deserialize(message, binData);
} catch (TException e) {
    _logger.error(e);
}

if (JLMessage._Fields.EXC.equals(message.getSetField())) {
    _logger.info("Received EXCEPTION message");
} else if (JLMessage._Fields.FRAME.equals(message.getSetField())) {
    _logger.info("Received FRAME message");
}

因此，在Java端仅记录“已接收的EXCEPTION消息”。对于JLFrame条消息，它会收到空JLException条消息。
