How to Process Decompress JSON Object using RabbitMQ Framework

Following code can be used to decompress a JSON File

public static byte[] decompress(byte[] data) throws IOException {
ByteArrayOutputStream out = new ByteArrayOutputStream();
IOUtils.copy(new GZIPInputStream(new ByteArrayInputStream(data)), out);
} catch(IOException e){
throw new RuntimeException(e);
return out.toByteArray();

and in our MessageListener implemented class use this code

byte[] decompressmessage = decompress(messageContent);
YourClass objYourClass = mapper.readValue(new String(decompressmessage), YourClass.class);

//YourClass code
import org.codehaus.jackson.annotate.JsonProperty;

public class YourClass {

@JsonProperty("EventNo") public String eventNo;
public String getEventNo() {
return eventNo;
public void setEventNo(String eventNo) {
this.eventNo = eventNo;
