Introducing Spring Framework

Chapter 16 ■ Messaging with Your Spring Application
Listing 16-2. RabbitMQConsumer.java
package com.apress.isf.spring.amqp;
import com.apress.isf.java.model.Document;
public interface RabbitMQConsumer{
public void process(Document document);
}
Listing 16-2 shows the RabbitMQConsumer interface; this interface will be the base for your three consumers
(remember, one per queue). Next, Listing 16-3 shows the first consumer, the PdfDocumentConsumer class.
Listing 16-3. PdfDocumentsConsumer.java
package com.apress.isf.spring.amqp;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import com.apress.isf.java.model.Document;
@Component("pdfConsumer")
public class PdfDocumentsConsumer implements RabbitMQConsumer{
private static final Logger log = LoggerFactory.getLogger(PdfDocumentsConsumer.class);
}
public void process(Document document) {
log.debug("PDF Document received: " + document);
}
Listing 16-3 shows the consumer that will be listening from the docs-pdf queue. Next, the TextDocumentsConsumer
class is shown in Listing 16-4.
Listing 16-4. TextDocumentsConsumer.java
package com.apress.isf.spring.amqp;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import com.apress.isf.java.model.Document;
@Component("textConsumer")
public class TextDocumentsConsumer implements RabbitMQConsumer{
private static final Logger log = LoggerFactory.getLogger(TextDocumentsConsumer.class);
}
public void process(Document document) {
log.debug("Text Document received: " + document);
}
