2.2 、spring boot项目配置中心config config 、

1、创建springboot项目 (不过依赖应该选择的是config server)
 
 
 
2、pom文件如下
<?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>

    <groupId>com.carl.auth</groupId>
    <artifactId>sso-config</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>sso-config</name>
    <description>Demo project for Spring Boot</description>

    <parent>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-parent</artifactId>
       <version>1.5.10.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>Edgware.SR2</spring-cloud.version>
    </properties>

    <dependencies>
      <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> 
3、添加配置管理器支持注解
 
@EnableConfigServer
 @SpringBootApplication
public class SsoConfigApplication {

    public static void main(String[] args) {
       SpringApplication.run(SsoConfigApplication.class, args);
    }
 } 
 
4、编辑 application配置文件
 
#指定日志输出文件
logging:
   file: "logs/sso-config.log"
info:
   name : "配置中心"

---
 server:
   #服务端口
port: 8888
   #访问路径
   context-path: /config
spring:
   profiles:
     #本地配置文件
     active:
       #配置文件本地化
       - native
   application:
     #指定应用名称
     name: sso-config 
5、运行这个spring boot项目，浏览器访问 http://localhost:8888/config/ 说明下面的启动成功
 
 
 
6、配置中心的位置，创建resource 下创建config文件夹，创建sso-dev.propetries 编辑配置文件
1、上面我们提到配置是放置于配置中心，而不放在服务内
2、由于配置是放在与本地，那么spring的默认配置在目录为resources/config

 
hello_key=value
 
 
7、重新启动spring boot项目，访问 http://localhost:8888/config/sso/dev
 
 
name:应用名称 sso -dev.properties配置文件的名称
label 表示分支名称
version 表示git上对应的版本号
{
"name": "sso",
         "profiles": ["dev"],
         "label": null,
         "version": null,
         "state": null,
         "propertySources": [{
"name": "classpath:/config/sso-dev.properties",
                  "source": {
                           "hello_key": "value"
                  }
         }]
}
