Java B2B2C多用戶商城 springboot架構-config-bus(十三)
簡介
當我們的業務系統越來越龐大復雜的時候,各種配置就會層出不群。一旦配置修改了,那麽我們就是必須修改後停服務,然後再上線,如果服務少,我們可以手動來操作,如果是成千上百的服務,如果是手動操作,肯定就不合適宜了,然後SpringCloudConfig就出來了,就是我們通常意義上的配置中心,把應用原本放在本地文件的配置抽取出來放在中心服務器,從而能夠提供更好的管理、發布能力。Java B2B2C多用戶商城 springboot架構-config-bus(十三)
SpringCloudConfig分服務端和客戶端,服務端負責將git(svn或本地文件系統)中存儲的配置文件發布成REST接口,客戶端可以從服務端REST接口獲取配置。但客戶端並不能主動感知到配置的變化,從而主動去獲取新的配置,這需要每個客戶端通過POST方法觸發各自的/refresh
SpringCloudBus通過一個輕量級消息代理連接分布式系統的節點。這可以用於廣播狀態更改(如配置更改)或其他管理指令。SpringCloudBus提供了通過POST方法訪問的endpoint/bus/refresh
,這個接口通常由git的webhook功能調用,用以通知各個SpringCloudConfig的客戶端去服務端更新配置,本節就講怎麽搭建一套自動刷新的spring cloud config
一、創建模塊
模塊結構如下:
二、maven聚合模塊microservice-config的pom.xml文件
<?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>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.4.5.RELEASE</version> </parent> <modelVersion>4.0.0</modelVersion> <groupId>com.jacky</groupId> <artifactId>miroservice-config</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>microservice-config-server</module> <module>microservice-config-eureka</module> <module>microservice-config-client</module> </modules> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> <docker.image.prefix>jacky</docker.image.prefix><!--配置鏡像倉庫的屬性--> <docker.repostory>192.168.6.132:5000</docker.repostory><!--配置鏡像倉庫的對應的地址與端口--> </properties> <dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>Camden.SR7</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> <!--添加利用maven插件構建docker鏡像的插件依賴--> <pluginManagement> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <version>0.4.13</version> </plugin> </plugins> </pluginManagement> </build> </project>
三、配置中心模塊(microservice-config-eureka)
3.1、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"> <parent> <artifactId>miroservice-config</artifactId> <groupId>com.jacky</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>microservice-config-eureka</artifactId> <packaging>jar</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka-server</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <executions> <!--設置在執行maven 的install時構建鏡像--> <execution> <id>build-image</id> <phase>install</phase> <goals> <goal>build</goal> </goals> </execution> </executions> <configuration> <!--安裝了docker的主機,並且打開了api remote接口設置--> <dockerHost>http://192.168.6.130:5678</dockerHost> <pushImage>true</pushImage><!--設置上傳鏡像到私有倉庫,需要docker設置指定私有倉庫地址--> <!--鏡像名稱--> <imageName>${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version}</imageName> <!--鏡像的基礎版本--> <baseImage>java:openjdk-8-jdk-alpine</baseImage> <!--鏡像啟動參數--> <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> </build> </project>
3.2、application.yml
spring: application: name: microservice-config-server security: basic: enabled: true user: name: jacky password: admin server: port: 9511 eureka: client: register-with-eureka: false fetch-registry: false service-url: defaultZone: http://jacky:admin@localhost:9511/eureka
3.3、啟動類EurekaApplication.java
package com.jacky.cloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer; @SpringBootApplication @EnableEurekaServer public class EurekaApplication { public static void main(String[] args) { SpringApplication.run(EurekaApplication.class, args); } }
3.3、啟動類EurekaApplication.java
package com.jacky.cloud; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer; @SpringBootApplication @EnableEurekaServer public class EurekaApplication { public static void main(String[] args) { SpringApplication.run(EurekaApplication.class, args); } }
四、配置中心服務端(microservice-config-server)
4.1、pom.xml文件
<?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> <artifactId>miroservice-config</artifactId> <groupId>com.jacky</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>microservice-config-server</artifactId> <packaging>jar</packaging> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-config-server</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-eureka</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-bus-amqp</artifactId> </dependency> <!--配置認證所需要的包--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>com.spotify</groupId> <artifactId>docker-maven-plugin</artifactId> <executions> <!--設置在執行maven 的install時構建鏡像--> <execution> <id>build-image</id> <phase>install</phase> <goals> <goal>build</goal> </goals> </execution> </executions> <configuration> <!--安裝了docker的主機,並且打開了api remote接口設置--> <dockerHost>http://192.168.6.130:5678</dockerHost> <pushImage>true</pushImage><!--設置上傳鏡像到私有倉庫,需要docker設置指定私有倉庫地址--> <!--鏡像名稱--> <imageName>${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version}</imageName> <!--鏡像的基礎版本--> <baseImage>java:openjdk-8-jdk-alpine</baseImage> <!--鏡像啟動參數--> <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint> <resources> <resource> <targetPath>/</targetPath> <directory>${project.build.directory}</directory> <include>${project.build.finalName}.jar</include> </resource> </resources> </configuration> </plugin> </plugins> </build> </project>
4.2、application.yml文件
