统一的配置管理中心
所需资源
- 一个服务端
- 一个客户端
- 一个Git配置中心仓库
服务端使用端口:8888
客户端使用端口:9000
先来开发服务端
三个步骤
- 添加依赖
- server的配置文件:application.properties
- 启动类添加注解
看一下具体的操作步骤
添加依赖,完整的pom.xml文件
<?xml version="1.0" encoding="UTF-8"?>

完整的application.properties文件
server.port=8888
spring.cloud.config.server.git.uri=https://git.oschina.net/sjk707069921/config-file.git//配置文件所在git仓库地址
启动类添加注解@EnableConfigServer
@SpringBootApplication
@EnableConfigServer
public class Learn03ConfigApplication {
public static void main(String[] args) {
SpringApplication.run(Learn03ConfigApplication.class, args);
}
}
服务端到此完成,但是别着急
git仓库还没创建
创建git仓库,提交两个文件
database-dev.properties
database.properties
内容也很简单
database-dev.properties文件内容
hello=dev file
database.properties文件内容
hello=this is product file
OK,到现在可以启动服务端,打开浏览器看一下 http://localhost:8888/database/dev
看到以下json表示服务端是OK的

接下来 开发客户端
也是三步
- 添加依赖
- 修改配置文件
- 测试
新建一个项目,添加依赖
<?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.example</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>1.5.3.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<repositories>
<repository>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</repository>
</repositories>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-config</artifactId>
<version>1.3.1.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-config</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
然后配置文件,这里注意,不能使用默认的application,propertis,而应将其重命名为bootstrap.properties
spring.application.name=database #这里要对应配置文件的名字
spring.cloud.config.profile=prod #使用哪个profile
spring.cloud.config.label=master #git仓库的分支
spring.cloud.config.uri=http://localhost:8888/ #服务器的地址
server.port=9000
OK,然后在启动类写一个测试,获取,并打印配置文件中的值
@SpringBootApplication
@EnableAutoConfiguration
@RestController
public class ConfigClientApplication {
public static void main(String[] args) {
SpringApplication.run(ConfigClientApplication.class, args);
}
@Value("${hello}")
private String foo;
@GetMapping("/hi")
public String hi(){
System.err.println(foo);
return
foo;
}
}
打开浏览器 ,访问 http://localhost:9000/hi
看到如下输出

至此,简单的配置中心开发完成.
