This article describes how to integrate Kafka send and receive message in a Springboot project.1. Resolve Dependencies FirstSpringboot related dependencies We don't mention it, and Kafka dependent only on one Spring-kafka integration packageHere we first show the configuration file#============== Kafka ================
Kafka is a messaging component in a distributed environment, and Kafka message components cannot be used if Kafka application processes are killed or Kafka machines are down.

A machine is not enough, then more than a few, first of all, start zookeepe
Kafka Producer APIsThere are two types of legacy Procuder APIs: Kafka.producer.SyncProducer and Kafka.producer.async.AsyncProducer. They all implement the same interface:[Java]View Plaincopy
Class Producer {
/ * Send the message to the specified partition * /
public void Send (kafka.javaapi.producer.producerdata
/ * Bulk send A batch of messages */
public void Send (java.util.list

public void Close ();

Apache Kafka is a distributed streaming platform. What exactly does that mean?We think of the three key capabilities of the streaming platform:1. Let you publish a subscription to the data stream. So he's a lot like a message queue and an enterprise-class messaging system.2. Lets you store data streams in a high-fault-tolerant manner.3. Let your data flow out of the current processing them.What is Kafka goo

Apache Kafka is a high-throughput distributed messaging system, open source by LinkedIn. Referring to Kafka's introduction to the official website: "Apache Kafka is publish-subscribe messaging rethought as a distributed commit log." Publish-subscribe "is the core idea of Kafka design, and also the most distinctive place

Kafka is a distributed, partitioned, and reproducible message system. It provides common messaging system functions, but has its own unique design. What is this unique design?

Introduction
Cluster installation:
I. preparations:
1. Version introduction:
Currently we are using a version of kafka_2.9.2-0.8.1 (scala-2.9.2 is officially recommended for Kafka, in addition to 2.8.2 and 2.10.2 available)
2. Environment preparation:
Install JDK 6. The current version is 1.6 and java_home is configured.
3. Configuration modification:
1) copy the online configuration to the local Kafka
: TextMessage, Mapmessage, Bytesmessage, Streammessage, ObjectMessage
Byte[] When actually applied, there are complex messages that can be serialized and sent.
Two, common MQ contrast

for receiving requests and storing the messages as files
The server returns the response result to the producer client
Consumer client application Consumer messages
The client Connection object wraps the consumer information into the request and sends it to the server.
