Stringペイロードを取得し、結果をLogFileTupleタイプとして返すプロクサーモジュールを作成しました。このモジュールはうまく動作します。
入力としてLogFileTupleを取得する別のモジュールを作成しました。ストリームをデプロイするときは、Source | Module1 | Module2 | SinkはMessageDeliveryExceptionです。Proccessor入力のSpring XDカスタムクラスタイプ
マイtransfor方法：
public Event transform(LogFileTuple payload) {
if (payload == null) {
return null;
}
try {
Event event = logParser.parse(payload);
if (event != null) {
return event;
} else {
logger.warn("LogParser result is null: {}.", payload);
return null;
}
} catch (Exception e) {
logger.warn("Cannot parse logFileTuple: {}.", payload, e);
return null;
}
}
Module2のための私のXML設定は次のとおりです。
<int:channel id="input" datatype="com.company.threatanalyzer.core.commons.tuple.LogFileTuple"/>
<int:transformer input-channel="input" output-channel="output">
<beans:bean class="com.company.threatanalyzer.xd.plugin.XdLogParser" />
</int:transformer>
<int:channel id="output"/>
私はこの例外を取得：
Caused by: org.springframework.messaging.MessageDeliveryException: Channel 'input' expected one of the following datataypes [class com.company.threatanalyzer.core.commons.tuple.LogFileTuple], but received [class com.company.threatanalyzer.core.commons.tuple.LogFileTuple]
