I. BACKGROUNDRecently made a small base component, the main role is asynchronous message notification, cache maintenance, and time-consuming task processing.In this process, the message notification and time-consuming tasks are handled using the open source RABBITMQ as the Message Center server.But a little bit more disgusting, I this component is to be executed in the existing system, that is, to upgrade the existing system, I use this component, and
Z OverviewThis article mainly describes how to use the RABBITMQ message agent to realize the communication between distributed systems, thus facilitating the loose coupling of microservices.RabbitMQ, also known as the open source message broker, supports a variety of message protocols and can be deployed on distributed systems. It is lightweight and easy to deploy applications. It primarily acts as a queue in which messages entered can be manipulated
Overview
For various reasons, up to now, rabbitmq has not implemented a priority queue, but only implemented priority processing for consumer.
However, for various reasons, Priority Queues are required at the application layer, so the requirement is: how to add priority queue features to rabbitmq.
After querying the information, I learned that although rabbitmq d

1. First I downloaded the rabbitmq-server from the officialHttp://www.rabbitmq.com/download.htmlOf course, the company is still based on Java development, so the download version is based on Linux below, but I am here to download an Ubuntu version, because I developed the machine is Ubuntu.Download well, install soon, Ubuntu under direct dpkg-i Rabbitmq-server_3.5.0-1_all.debOf course other Linux systems ca
Objective
In the last section, the use of the cache database redis , in the actual work, generally in the system or application communication or asynchronous notification (after login to send text messages or mail, etc.), will use Message Queuing to solve this business scenario decoupling problem. This section explains the RabbitMQ integration and simple use examples of Message Queuing.

Reprinted from the message middleware Activemq, RABBITMQ, ROCKETMQ, ZeroMQ, Kafka how to choose.
Recently to the company's Message Queuing middleware selection, the market related to open source technology is very much, such as ACTIVEMQ, RABBITMQ, ZeroMQ, Kafka, as well as Alibaba's rocketmq and so on.
So much technology, how to choose it.
First for Ali's ROCKETMQ, because it is Ali Open source, for the d
One, why the news lost
RABBITMQ switches and queues and messages are not persisted by default, that is, after the server restarts or after the downtime is restored, the previously created switches and queues will no longer exist and the previously unused messages are gone. The reason is the durable property of each queue and switch. The default for this property is False, which determines whether the RABBITMQ
, where x is the channel ID you want to use. In general, it is recommended to use the. CreateChannel () method to automatically assign channel identities to prevent collisions. Queue Declaration
Now we have a connection and channel that we can use. Now, our code will be divided into two applications, producers (producer) and consumers (consumer). We first create a consumer program that creates a queue called "Test_push" and a switch called "Sorting_room":
String queue = "Test_push";

Introduction:
RabbitMQ has two projects integrated with Spring. One project is the message producer, responsible for sending messages, and the other is the message consumer, responsible for listening to messages. The genera

I. Installation of ErlangSince the RABBITMQ Linux operating environment requires an Erlang environment, it is necessary to install Erlang first;1. Erlang Download:http://erlang.org/download/(i downloaded the otp_src_R16B.tar.gz version)2. Check the dependency package:Make GCC gcc-c++ kernel-devel M4 ncurses-devel openssl-devel tk unixODBC unixodbc-devel xmlto glibc MPFRUse Rpm-qa MAKE/GCC and so on to check whether it is installed;Use RPM-IVH MAKE/GCC
