Spring Cloud Config

One, Spring Cloud Config Server

Create a new spring boot project named Configserver

1.pom.xml adding dependencies

<?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" > <modelversion>4.0.0 </modelVersion> <groupId>com.dzpykj</groupId> <artifactid>configserver</artifactid > <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>configserve R</name> <description>demo Projectfor   Spring boot</description> <parent> <groupId>org.springframework.boot</groupId> &        Lt;artifactid>spring-boot-starter-parent</artifactid> <version>1.5.9.RELEASE</version> <relativepath/> <!--lookup parent from repository--</parent> <properties> &LT;PR Oject.build.sourceencoding>utf-8</project.build.sourceencoding> <project.reporting.outputencoding >UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties&    Gt <dependencyManagement> <dependencies> <dependency> <groupid>org.s                Pringframework.cloud</groupid> <artifactId>spring-cloud-dependencies</artifactId> <version>Edgware.RELEASE</version> <type>pom</type> <scop E>import  </scope> </dependency> </dependencies> </dependencyManagement> <depende ncies> <dependency> <groupId>org.springframework.boot</groupId> <arti factid>spring-boot-starter-web</artifactid> </dependency> <dependency> <g Roupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-test</artifactid&gt            ; <scope>test</scope> </dependency> <dependency> &LT;GROUPID&GT;ORG.SPRINGF Ramework.cloud</groupid> <artifactId>spring-cloud-starter-eureka</artifactId> &LT;/DEP endency> <dependency> <groupId>org.springframework.cloud</groupId> <a rtifactid>spring-cloud-config-server</artifactid> </dependency> </dependencies> <buil      D>  <plugins> <plugin> <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins>            </build> <repositories> <repository> <id>spring-milestones</id> <name>spring milestones</name> <url>https://repo.spring.io/milestone</url><snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories></project>

2.application.properties Adding a configuration

server.port=8768spring.application.name=Configservereureka.client.serviceUrl.defaultZone= http://localhost:8761/eureka/spring.cloud.config.server.git.uri=https:// github.com/pinbo1991/springcloud/Spring.cloud.config.label=master

Spring.cloud.config.server.git.uri is the GitHub address (the configuration file address in this demo is Https://github.com/PinBo1991/springcloud)

Spring.cloud.config.label for GitHub Branch

3. Start the class plus annotations @enableconfigserver to open the service side of Spring Cloud config

 Packagecom.dzpykj;Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.SpringBootApplication;ImportOrg.springframework.cloud.config.server.EnableConfigServer;Importorg.springframework.cloud.netflix.eureka.enableeurekaclient;@ Springbootapplication@enableeurekaclient@enableconfigserver Public classconfigserverapplication { Public Static voidMain (string[] args) {Springapplication.run (configserverapplication.class, args); }}

Second, Spring Cloud Config Client

New spring Boot project, named Configclient

1.pom.xml adding dependencies

<?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" > <modelversion>4.0.0 </modelVersion> <groupId>com.dzpykj</groupId> <artifactid>configclient</artifactid > <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>configclien T</name> <description>demo Project for Spring boot</description> <parent> <groupId>org.springframework.boot</groupId> &        Lt;artifactid>spring-boot-starter-parent</artifactid> <version>1.5.9.RELEASE</version> <relativepath/> <!--lookup parent from repository--</parent> <properties> &LT;PR Oject.build.sourceencoding>utf-8</project.build.sourceencoding> <project.reporting.outputencoding >UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties&    Gt <dependencyManagement> <dependencies> <dependency> <groupid>org.s                Pringframework.cloud</groupid> <artifactId>spring-cloud-dependencies</artifactId> <version>Edgware.RELEASE</version> <type>pom</type> <scop E>import  </scope> </dependency> </dependencies> </dependencyManagement> <depende ncies> <dependency> <groupId>org.springframework.boot</groupId> <arti factid>spring-boot-starter-web</artifactid> </dependency> <dependency> <g Roupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-test</artifactid&gt            ; <scope>test</scope> </dependency> <dependency> &LT;GROUPID&GT;ORG.SPRINGF Ramework.cloud</groupid> <artifactId>spring-cloud-starter-eureka</artifactId> &LT;/DEP endency> <dependency> <groupId>org.springframework.cloud</groupId> <a rtifactid>spring-cloud-starter-config</artifactid> </dependency> </dependencies> <bui     Ld>   <plugins> <plugin> <groupId>org.springframework.boot</groupId>    <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins>            </build> <repositories> <repository> <id>spring-milestones</id> <name>spring milestones</name> <url>https://repo.spring.io/milestone</url><snapshots> <enabled>false</enabled> </snapshots> </repository> </repositories></project>

2. Rename the application.properties to Bootstrap.properties and add the configuration

server.port=8769spring.application.name=Configclienteureka.client.serviceUrl.defaultZone= http://localhost:8761/eureka/spring.cloud.config.label=  Masterspring.cloud.config.profile=Testspring.cloud.config.uri= http://localhost:8768 /spring.cloud.config.discovery.enabled=true

Configuration Item Description:

Spring.application.name: The {application} section in the corresponding pre-configuration file
Spring.cloud.config.profile: The {profile} section in the corresponding pre-configuration file
Spring.cloud.config.label: Git branch that corresponds to the pre-configuration file
Spring.cloud.config.uri: Address of the configuration center

/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties

The configuration of this configuration file means: in Configserver spring.cloud.config.server.git.uri (ie, https://github.com/PinBo1991/springcloud/), look for

Configuration file for Configclient profile/spring.cloud.config.label/spring.application.name-spring.cloud.config.profile.properties (ie configclient-test.properties)

3. Startup class

 Packagecom.dzpykj;ImportOrg.springframework.beans.factory.annotation.Value;Importorg.springframework.boot.SpringApplication;Importorg.springframework.boot.autoconfigure.SpringBootApplication;Importorg.springframework.cloud.netflix.eureka.EnableEurekaClient;Importorg.springframework.web.bind.annotation.RequestMapping;Importorg.springframework.web.bind.annotation.restcontroller;@ Springbootapplication@enableeurekaclient@restcontroller Public classconfigclientapplication {@Value ("${configclientkey}") String Configclientkey; @RequestMapping (Value= "/getconf")     PublicString getconf () {returnConfigclientkey; }         Public Static voidMain (string[] args) {Springapplication.run (configclientapplication.class, args); }}

Configclient-test.properties file with CONFIGCLIENTKEY=ZXCV configuration, read it out

Third, test, visit Configclient project: http://127.0.0.1:8769/getConf
