14:08:14.892 [simpleasynctaskexecutor-1] debug o.s.a.r.l.blockingqueueconsumer - retrieving delivery consumer: tags=[{amq.ctag-rdkzctoxlmwqf4ffuihs0a=notificationqueue}], channel=cached rabbit channel: amqchannel(amqp://guest@127.0.0.1:5672/,3), conn: proxy@47914ea3 shared rabbit connection: simpleconnection@1096fe75 [delegate=amqp://guest@127.0.0.1:5672/], acknowledgemode=auto local queue size=0 14:08:14.913 [simpleasynctaskexecutor-3] debug o.s.a.r.l.blockingqueueconsumer - retrieving delivery consumer: tags=[{amq.ctag-jxyjmkfw6heu77xvdyh3tw=notificationqueue}], channel=cached rabbit channel: amqchannel(amqp://guest@127.0.0.1:5672/,2), conn: proxy@47914ea3 shared rabbit connection: simpleconnection@1096fe75 [delegate=amqp://guest@127.0.0.1:5672/], acknowledgemode=auto local queue size=0 14:08:14.917 [simpleasynctaskexecutor-2] debug o.s.a.r.l.blockingqueueconsumer - retrieving delivery consumer: tags=[{amq.ctag-acbx0r5em-ukqwn0a_nrwa=notificationqueue}], channel=cached rabbit channel: amqchannel(amqp://guest@127.0.0.1:5672/,1), conn: proxy@47914ea3 shared rabbit connection: simpleconnection@1096fe75 [delegate=amqp://guest@127.0.0.1:5672/], acknowledgemode=auto local queue size=0 14:08:15.893 [simpleasynctaskexecutor-1] debug o.s.a.r.l.blockingqueueconsumer - retrieving delivery consumer: tags=[{amq.ctag-rdkzctoxlmwqf4ffuihs0a=notificationqueue}], channel=cached rabbit channel: amqchannel(amqp://guest@127.0.0.1:5672/,3), conn: proxy@47914ea3 shared rabbit connection: simpleconnection@1096fe75 [delegate=amqp://guest@127.0.0.1:5672/], acknowledgemode=auto local queue size=0 

it's ever ending.kindly find below consumer code:

notificationconsumer.java

@component public class notificationconsumer {  private static final logger logger = loggerfactory.getlogger(notificationconsumer.class);  @value("${notification.queue}") public string notificationqueue;  @rabbitlistener(id="notification",containerfactory="rabbitlistenercontainerfactory",queues = "#{notificationqueue}") public void handlenotificationmessage(transaction transaction) {     system.out.println("entered handlenotificationmessage::"+transaction.getid());     system.out.println("exit handlenotificationmessage::"+transaction.getdata());      logger.info("entered handlenotificationmessage::", transaction.getid());     logger.info("exit handlenotificationmessage::", transaction.getdata()); }  @bean public queue notificationqueue() {     return new queue(notificationqueue, true, false, false); }  } 

application.yml

spring:     rabbitmq:         addresses: 127.0.0.1:5672         adminaddresses: http://127.0.0.1:15672         username: guest         password: guest         requested-heartbeat: 60  spring.rabbit.exchange: notification-exchange notification.queue: notificationqueue concurrent.consumers: 3 max.concurrent.consumers: 10 

message produced application , application consume message.

your should appreciated.

as per gary flipped logger level debug info resolved issue.

logging:     level:         root: info 

now getting following exception:

15:21:24.925 [simpleasynctaskexecutor-2] warn o.s.a.r.l.conditionalrejectingerrorhandler - fatal message conversion error; message rejected; dropped or routed dead letter exchange, if configured: (body:'{"id":"5784eed4f5a64b4d8663e706","clientidentifier":"313131313131", "data":"sample data vad","currentaction":{"state":{"status":"pending","errorcode":"404"},"data":"sample data"}, "haserror":false,"errormessage":""}'messageproperties [headers={__typeid__=com.global.produce.model.transaction}, timestamp=null, messageid=null, userid=null, appid=null, clusterid=null, type=null, correlationid=null, replyto=null, contenttype=application/json, contentencoding=utf-8, contentlength=0, deliverymode=persistent, expiration=null, priority=0, redelivered=false, receivedexchange=, receivedroutingkey=notificationqueue, deliverytag=1, messagecount=0])

anyone have idea error?

that's debug log; change log settings info or warn or error.
