Springcloud-config-bus (13)

Brief introduction

When our business systems become more and more complex, various configurations can be layered out of the pack. Once the configuration has been modified, then we have to modify the after-stop service, and then go online, if the service is small, we can manually operate, if it is hundreds of services, if it is manual operation, it is certainly inappropriate, and then springcloudconfig out, Is our usual sense of the configuration center, the application originally placed in the local file configuration extracted from the central server, so as to provide better management, publishing capabilities.

Springcloudconfig sub-server and client, the server is responsible for the GIT (SVN or local file system) stored in the configuration file as a rest interface, the client can get the configuration from the server side rest interface. However, the client is not actively aware of the changes to the configuration, thereby proactively acquiring a new configuration, which requires each client to trigger its own through the Post method /refresh .

Springcloudbus connects the nodes of a distributed system through a lightweight message broker. This can be used for broadcast state changes (such as configuration changes) or other management directives. Springcloudbus provides a endpoint that is accessed via the Post method, which is /bus/refresh typically called by the Webhook function of Git to notify the client of each springcloudconfig to update the configuration on the server. This section will tell you how to build a set of Spring Cloud Config automatically refreshed

First, create the module

The modules are structured as follows:

Second, Maven aggregation module Microservice-config pom.xml file

<?xml version= "1.0" encoding= "UTF-8"? ><project xmlns= "http://maven.apache.org/POM/4.0.0"Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xsi:schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" > <parent> <groupid&        Gt;org.springframework.boot</groupid> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.5.RELEASE</version> </parent> <modelVersion>4.0.0</modelVersion> <g Roupid>com.jacky</groupid> <artifactId>miroservice-config</artifactId> <packaging>pom </packaging> <version>1.0-SNAPSHOT</version> <modules> <module>microservice-con Fig-server</module> <module>microservice-config-eureka</module> <module>microservice -config-client</module> </modules> <properties> <project.build.sourceencoding>utf-8& Lt;/project.build.sourceencoding> <project.reporting.outputencoding>utf-8</ Project.reporting.outputencoding> <java.version>1.8</java.version> <docker.image.prefix>jacky</docker.image.prefix><!--Configuring the properties of a mirrored warehouse-- > <docker.repostory>192.168.6.132:5000</docker.repostory><!--Configure the corresponding address and port of the mirrored warehouse--</proper ties> <dependencyManagement> <dependencies> <dependency> <gro Upid>org.springframework.cloud</groupid> <artifactid>spring-cloud-dependencies</artifacti                D> <version>Camden.SR7</version> <type>pom</type> <scope>Import</scope> </dependency> </dependencies> </dependencyManagement> <build&        Gt                <plugins> <plugin> <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> <!--add plug-ins to build Docker images with Maven plugins--<pluginManagement> <plugins> < Plugin> <groupId>com.spotify</groupId> <artifactid>docker-maven            -plugin</artifactid> <version>0.4.13</version> </plugin> </plugins> </pluginManagement> </build> </project>

Third, Configuration Center module (MICROSERVICE-CONFIG-EUREKA)
