序列化和反序列化嵌套结构体 throw “Expected array, but got raw value” error. msgpack是否支持嵌套结构体的序列化和反序列化

[zlp821130]

我在C++端序列化nested struct RequestBody，并发送到Java端反序列化 C++结构体和序列化方法如下： struct RESP_GHM { int uiYear; // 年 char szMs[3]; // 毫秒

MSGPACK_DEFINE(uiYear, szMs);  // 定义要序列化的成员

};

/*

• @brief 测试消息体结构体 */ struct RequestBody { int id; string msg; vector usCmdWork; vector usTestString; short usWave[3][4]; RESP_GHM ghm;

  MSGPACK_DEFINE(id, msg, usCmdWork, usTestString, usWave, ghm); // 定义要序列化的成员 };

// 序列化方法 template<typename T> string MsgpackSerialize(const T& obj) {

stringstream buffer;

// 序列化数据
pack(buffer, obj);
buffer.seekg(0);

string bufferStr(buffer.str());

return bufferStr;

}；

Java端反序列化代码如下

// java反序列化代码 public <T> T deserialize(byte[] data, String classOfT) throws CodecException {

    Object resultObject = null;
    MessagePack messagePack = new MessagePack();

    try {
        Class<?> clazz = Class.forName(classOfT);
        resultObject = messagePack.read(data, clazz);

    } catch (ClassNotFoundException e) {
        throw new CodecException(
                classOfT + " ClassNotFoundException occurred when Msgpack serializer decode!", e);
    } catch (IOException e) {
        throw new CodecException("IOException occurred when Msgpack serializer decode!", e);
    }

    return (T) resultObject;
}

执行到resultObject = messagePack.read(data, clazz); //throw “Expected array, but got raw value”。

注: 如果RequestBody中不嵌套RESP_GHM 结构体，Java端能够正常反序列化，msgpack是否支持嵌套结构体的序列化和反序列化？

java 端的两个实体 @Message public class RESP_GHM implements Serializable {

int uiYear;            // 年
char[] szMs = new char[3];            // 毫秒

public int getUiYear() {
    return uiYear;
}

public void setUiYear(int uiYear) {
    this.uiYear = uiYear;
}

public char[] getSzMs() {
    return szMs;
}

public void setSzMs(char[] szMs) {
    this.szMs = szMs;
}

}

@zlp821130 You're using msgpack-java v6? If so, it's not supported now, unfortunately.
