一直使用springboot搭建後端項目,全部的配置都寫到本身的resource目錄下,隨着微服務的項目愈來愈多,每一個項目都須要本身的各類配置文件。並且後期一旦想要修改配置文件,就得從新發布一遍很是的麻煩,如今就來教教你們怎麼統一在github上管理 這些配置,並作到一處修改到處生效,不須要從新發布項目。
可使用STS來初始化項目,選擇本身的以來就好。java
<?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> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.4.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.mike</groupId> <artifactId>config-server</artifactId> <version>0.0.1-SNAPSHOT</version> <name>config-server</name> <description>config server</description> <properties> <java.version>1.8</java.version> <spring-cloud.version>Greenwich.SR1</spring-cloud.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter</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> </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> </project>
建立bootstrap.yml
文件,固然你可使用application.yml
或application.properties
git
spring: application: name: config-repo cloud: config: server: git: uri: https://github.com/mike/config-repo.git #github倉庫地址 username: mike # 用戶名 password: 123456 # 密碼
在github上建立一個config-repo倉庫,並添加配置文件:
兩個不一樣環境的配置hello-pj-dev.yml
github
hello: text: hello spring dev
hello-pj-uat.yml
web
hello: text: hello spring uat
建立啓動類:spring
@SpringBootApplication @EnableConfigServer public class ConfigServerApplication { public static void main(String[] args) { SpringApplication.run(ConfigServerApplication.class, args); } }
啓動應用,訪問:
http://localhost:8080/hello-pj-dev.yml
http://localhost:8080/hello-pj-uat.yml
你就能夠看到遠程的配置中心。apache
pom
bootstrap
<?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> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.4.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.mike</groupId> <artifactId>hello-server</artifactId> <version>0.0.1-SNAPSHOT</version> <name>hello-server</name> <description>hello server</description> <properties> <java.version>1.8</java.version> <spring-cloud.version>Greenwich.SR1</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> </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> </project>
建立bootstrap.yml
文件,只能是這個文件,不能是application文件後端
server: port: 8082 spring: application: name: hello-pj cloud: config: profile: dev uri: http://localhost:8080/
這裏面配置了讀取遠程配置文件的uri,注意application.name必須對應github上的文件名,最終訪問的是application.name+profilespringboot
建立測試controllerapp
@RestController public class TestController { @Value("${hello.text}") private String text; @GetMapping("/say") public String sayHello(){ return text; } }
訪問 http://localhost:8082/say,你就能夠看到對應的配置。這樣你只須要在github上管理全部的配置就好了,可是記得'config-server'工程得一直啓動,經過它咱們才能獲取github上的配置。
目前若是咱們修改了github上的配置並不能立刻生效,須要咱們的客戶端工程重啓才行,如今須要改形成自動刷新。
在客戶端工程中加入新的依賴:
<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-bus-amqp</artifactId> </dependency>
修改bootstrap.yml
文件
server: port: 8082 spring: application: name: hello-pj cloud: config: profile: dev uri: http://localhost:8080/ bus: trace: enabled: true rabbitmq: host: localhost port: 5672 username: guest password: guest
注意
須要藉助rabbitmq
,因此本地須要啓動rabbitmq
。
在須要刷新的地方加入註解@RefreshScope
@RestController @RefreshScope public class TestController { @Value("${hello.text}") private String text; @GetMapping("/say") public String sayHello(){ return text; } }
這樣咱們既能夠隨時修改github上的配置文件,而不須要重啓應用。
若是對你有幫助,但願能夠關注下個人公衆號:
