redisMQ消费消息的机制

System.out.println("message received:" + messageStr);try {TimeUnit.SECONDS.sleep(10);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}System.out.println("message ddddreceived:" + messageStr);

输出 为什么是这个顺序?

message received:0
message received:1
message received:2
message received:3
message received:4
message received:5
message received:6
message received:7
message received:8
message received:9
message received:10

message ddddreceived:0
message ddddreceived:1
message ddddreceived:2
message ddddreceived:3
message ddddreceived:4
message ddddreceived:5
message ddddreceived:6
message ddddreceived:7
message ddddreceived:8
message ddddreceived:9
message ddddreceived:10
