(九)整合spring cloud云服务架构 - commons

1. 介绍

Spring Cloud Config为分布式系统中的外部配置提供服务器和客户端支持。使用Config Server，您可以在所有环境中管理应用程序的外部属性。客户端和服务器上的概念映射与SpringEnvironment和PropertySource抽象相同，因此它们与Spring应用程序非常契合，但可以与任何以任何语言运行的应用程序一起使用。随着应用程序通过从开发人员到测试和生产的部署流程，您可以管理这些环境之间的配置，并确定应用程序具有迁移时需要运行的一切。服务器存储后端的默认实现使用git，因此它轻松支持标签版本的配置环境，以及可以访问用于管理内容的各种工具。很容易添加替代实现，并使用Spring配置将其插入。

2. 引入pom相关jar包，其中pom.xml配置如下：

<?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>com.ml.honghu</groupId>          <artifactId>commonservice</artifactId>          <version>0.0.1-SNAPSHOT</version>      </parent>            <artifactId>commonservice-config</artifactId>      <packaging>jar</packaging>        <name>commonservice-config</name>      <description>Config Server</description>        <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.boot</groupId>                      <artifactId>spring-boot-starter-security</artifactId>              </dependency>          <dependency>              <groupId>org.springframework.boot</groupId>              <artifactId>spring-boot-starter-test</artifactId>              <scope>test</scope>          </dependency>      </dependencies>        <build>          <plugins>              <plugin>                  <groupId>org.springframework.boot</groupId>                  <artifactId>spring-boot-maven-plugin</artifactId>                  <executions>                      <execution>                          <id>1</id>                          <goals>                              <goal>repackage</goal>                          </goals>                      </execution>                                      <execution>                                          <id>2</id>                                              <goals>                                                     <goal>build-info</goal>                                              </goals>                                      </execution>                  </executions>              </plugin>          </plugins>      </build>  </project>  

 3. 在src/main/java进行ConfigApplication.java启动文件配置：

package com.ml.honghu;    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;    @EnableConfigServer  @EnableEurekaClient  @SpringBootApplication  public class ConfigApplication {        public static void main(String[] args) {          SpringApplication.run(ConfigApplication.class, args);      }  }  

 4. 在src/main/resource下进行bootstrap.yml配置

server:   port: 8888  spring:    application:      name: commonservice-config-server    profiles:      active: discovery,native    cloud:      config:        server:          git:            uri: http://192.168.0.254/honghu.../honghu-config.git            username: honghu            password: 123456            searchPaths: config-dev  security:    basic:      enabled: true    user:      name: honghu      password: 123456  eureka:    client:      serviceUrl:        defaultZone: http://honghu:123456@localhost:8761/eureka/        honghuZone: http://honghu:123456@localhost:8761/eureka/      registry-fetch-interval-seconds: 300      availability-zones:        honghu: honghuZone    instance:      prefer-ip-address: true      metadataMap:        version: 1.0        variant: A        user: ${security.user.name}        password: ${security.user.password}  management:    security:      enabled: false  

 注意： 如果不从远程git或者svn库加载配置文件信息，可以配置加载本地地址，比如window下配置使用：

server:   port: 8888  spring:    application:      name: commonservice-config-server    profiles:      active: discovery,native    cloud:      config:        server:          <span style="color: #ff0000;">native.searchLocations: d:/honghu-config</span>  security:    basic:      enabled: true    user:      name: honghu      password: 123456  eureka:    client:      serviceUrl:        defaultZone: http://honghu:123456@localhost:8761/eureka/        honghuZone: http://honghu:123456@localhost:8761/eureka/      registry-fetch-interval-seconds: 300      availability-zones:        honghu: honghuZone    instance:      prefer-ip-address: true      metadataMap:        version: 1.0        variant: A        user: ${security.user.name}        password: ${security.user.password}  management:    security:      enabled: false  

 到此，整个config服务项目配置完毕！！
