1.构建config-server
创建一个pom.xml
<?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.bennytitan</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>2.0.0.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> <spring-cloud.version>Finchley.RELEASE</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- 新增依赖 --> <dependency> <groupId>com.fasterxml</groupId> <artifactId>classmate</artifactId> <version>1.4.0</version> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</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>public</id> <name>aliyun nexus</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>public</id> <name>aliyun nexus</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> </pluginRepositories> </project>
ConfigServerApplication.java
package com.bennytitan.configserver; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.config.server.EnableConfigServer; @SpringBootApplication @EnableConfigServer public class ConfigServerApplication { public static void main(String[] args) { SpringApplication.run(ConfigServerApplication.class, args); } }
application.properties
spring.application.name=config-server server.port=8888 eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/ #spring.cloud.config.server.git.uri=https://gitee.com/JeeGemEdu/SpringCloudConfig/ spring.cloud.config.server.git.uri=https://github.com/forezp/SpringcloudConfig/ spring.cloud.config.server.git.searchPaths=respo spring.cloud.config.label=master spring.cloud.config.server.git.username= spring.cloud.config.server.git.password=
启动服务,浏览器输入http://localhost:8888/foo/dev,得到下图结果表示config状态正常,可以远程取用配置文件了
http请求地址和资源文件映射如下:
- /{application}/{profile}[/{label}]
- /{application}-{profile}.yml
- /{label}/{application}-{profile}.yml
- /{application}-{profile}.properties
- /{label}/{application}-{profile}.properties
2.构建一个config client
pom.xml:
<?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.bennytitan</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>2.0.0.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> <spring-cloud.version>Finchley.RELEASE</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-config</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- 新增依赖 --> <dependency> <groupId>com.fasterxml</groupId> <artifactId>classmate</artifactId> <version>1.4.0</version> </dependency> </dependencies> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>${spring-cloud.version}</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>public</id> <name>aliyun nexus</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>public</id> <name>aliyun nexus</name> <url>http://maven.aliyun.com/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>false</enabled> </snapshots> </pluginRepository> </pluginRepositories> </project>
ConfigClientApplication.java
package com.bennytitan.configclient; import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController; @SpringBootApplication@RestControllerpublic class ConfigClientApplication { public static void main(String[] args) { SpringApplication.run(ConfigClientApplication.class, args); } @Value("${foo}") String foo; @RequestMapping(value = "/hi") public String hi(){ return foo; }}
application.properties
spring.application.name=config-client spring.cloud.config.label=master spring.cloud.config.profile=dev spring.cloud.config.uri= http://localhost:8888/ server.port=8881
打开网址访问:http://localhost:8881/hi,网页显示:
3.高可用分布式配置
上面的config-server已经配置好了,如果可以,可以启动多个config-server。
主要是改造config-client的pom.xml增加客户端服务管理:
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency>
然后application.properties的配置如下,这里都不需要指定config-server的IP地址,直接通过服务ID就能获取到了:
spring.application.name=config-client spring.cloud.config.label=master spring.cloud.config.profile=dev #spring.cloud.config.uri= http://localhost:8888/ eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/ spring.cloud.config.discovery.enabled=true spring.cloud.config.discovery.serviceId=config-server server.port=8881
测试,访问http://localhost:8881/hi,浏览器显示:
