SpringCloudConfig配置中心git库以及refresh刷新
基于git库的Spring Cloud Config配置中心代码demo下载地址：https://gitlab.com/mySpringCloud/config-git
SpringBoot版本: 1.5.9.RELEASE
SpringCloud版本：Edgware.RELEASE
1、Spring Cloud Config Server 服务端
bootstrap.properties配置：
server.port=8001 spring.application.name=config-server-git eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/ #关闭刷新安全认证 management.security.enabled=false spring.cloud.config.server.git.uri=https://gitlab.com/mySpringCloud/config-git/springcloudconfig.git spring.cloud.config.server.git.searchPaths=respo spring.cloud.config.label=master spring.cloud.config.server.git.username=princess-azalea@qq.com spring.cloud.config.server.git.password=qqGroup49167765
pom.xml配置：
<?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.forezp</groupId> <artifactId>config-server</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>config-server</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath /> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-client</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Edgware.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <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>
启动类：
package com.forezp; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.config.server.EnableConfigServer; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; @SpringBootApplication @EnableConfigServer @EnableEurekaClient public class ConfigServerApplication { public static void main(String[] args) { SpringApplication.run(ConfigServerApplication.class, args); } }
controller类：
package com.forezp.controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /* * 启动config client之前，要先访问config server端的任意url，要不然config client启动失败，报错为某个值@Value注入失败，原因不明。 * */ @RestController public class ConfigServerController { @RequestMapping(value = "/hi") public String hi(){ return "Hi this is Config Server!"; } }
2、Spring Cloud Config Client 客户端
bootstrap.properties配置：
server.port=8002 spring.application.name=config-client-git spring.cloud.config.label=master spring.cloud.config.profile=dev #spring.cloud.config.uri= http://localhost:8888/ #关闭刷新安全认证 management.security.enabled=false eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/ spring.cloud.config.discovery.enabled=true spring.cloud.config.discovery.serviceId=config-server-git
pom.xml配置：
<?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.forezp</groupId> <artifactId>config-client</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>config-client</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.9.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Edgware.RELEASE</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <build> <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>
启动类：
package com.forezp; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.EnableEurekaClient; @SpringBootApplication @EnableEurekaClient public class ConfigClientApplication { public static void main(String[] args) { SpringApplication.run(ConfigClientApplication.class, args); } }
controller类：
package com.forezp.controller; import org.springframework.beans.factory.annotation.Value; import org.springframework.cloud.context.config.annotation.RefreshScope; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; /** * 验证刷新步骤： * 1、http://localhost:8002/hi 请求获取foo值 * 2、更改git库里foo值 * 3、http://localhost:8002/refresh 刷新某个微服务里的值，需类里加上注解@RefreshScope，并且jar依赖有spring-boot-starter-actuator * 4、http://localhost:8002/hi 获取新的foo值 * * @author zhuwen * */ @RestController @RefreshScope public class ConfigClientController { @Value("${foo}") String foo; @RequestMapping(value = "/hi") public String hi(){ return foo; } }
