В предыдущем вопросе Как создать работающий сокет TCP-сервера при весенней загрузке и как обрабатывать входящее сообщение? У меня возникли некоторые проблемы с интеграцией spring и обработкой TCP подключение к розетке. Эта проблема решена, но, к сожалению, появилась новая... Я получил свое сообщение от клиента - пока все хорошо, но теперь я попытался использовать уже существующую бизнес-логику для обработки сообщения следующим образом:
Это класс для обработки входящего сообщения сокета. Реализовано с помощью интеграции Spring
import homebrew.something.MessageProcessor;
import lombok.extern.log4j.Log4j2;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.integration.annotation.MessageEndpoint;
import org.springframework.integration.annotation.ServiceActivator;
import org.springframework.stereotype.Component;
@Log4j2
@Component
@MessageEndpoint
public class ClientSocketHandler {
@Autowired
private MessageProcessor messageProcessor;
@ServiceActivator(inputChannel = "toTcp")
public byte[] handleMessage(byte[] msg) {
byte[] msgToSend = messageProcessor.processMessage(msg);
return msgToSend;
}
}
Это обычный класс объектов передачи, привязанный к сеансу HTTP
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import org.springframework.context.annotation.Scope;
import org.springframework.context.annotation.ScopedProxyMode;
@Component
@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
public class ASimpleTransferObject {
// Some fields,
// some getters and
// some setters
}
Здесь мы получили наш сервис для обработки входящего сообщения из сокета TCP
import lombok.extern.log4j.Log4j2;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
@Log4j2
@Service
public class MessageProcessor {
@Autowired
private ASimpleTransferObject transferObject;
public byte[] processMessage(byte[] msg) {
// Do something with the message
return message;
}
}
Если я отправляю сообщение с клиента на сервер, возникает это исключение:
ERROR org.springframework.integration.ip.tcp.connection.TcpNetConnection - Exception sending message: GenericMessage [payload=byte[0], headers={ip_tcp_remotePort=XXXX, ip_connectionId=view-localhost:XXXXX:YYYYY:AAAA-BBBB-CCCC, ip_localInetAddress=/127.0.0.1, ip_address=127.0.0.1, id=fd33bdd9-1af1-051f-3106-3f08af7bdd16, ip_hostname=view-localhost, timestamp=87236587436545}]

Я уже пытался поместить RequestContextListener в свою весеннюю конфигурацию.
@Bean
public RequestContextListener requestContextListener() {
return new RequestContextListener();
}
но это особо не помогло. То же самое исключение было выбрано снова.
Есть ли решение этой проблемы?
Заранее большое спасибо!
