刚接触spring cloud 的；做了一个svn做配置文件仓库demo；

创建一个spring boot工程作为 spring cloud config server ;下面是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">    <modelVersion>4.0.0</modelVersion>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.2.3.RELEASE</version>        <relativePath /> <!-- lookup parent from repository -->    </parent>    <groupId>com.honkib.springcloud</groupId>    <artifactId>spring-cloud-config-server</artifactId>    <version>1.0-SNAPSHOT</version>    <dependencyManagement>        <dependencies>            <dependency>                <groupId>org.springframework.cloud</groupId>                <artifactId>spring-cloud-config</artifactId>                <version>1.0.4.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>        <!--表示为web工程-->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <!--暴露各种指标-->        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-actuator</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-config-server</artifactId>        </dependency>                 <!--config server need read svn-->        <dependency>            <groupId>org.tmatesoft.svnkit</groupId>            <artifactId>svnkit</artifactId>            <version>1.8.10</version>        </dependency>    </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>    </build></project>

configserver程序结构：

然后创建一个application.java 类

package com.hobkib.cloud.demo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.EnableAutoConfiguration;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.config.server.EnableConfigServer;import org.springframework.context.annotation.Configuration;import org.springframework.web.bind.annotation.RestController;/** * Created by liaokailin on 16/4/28. */@Configuration@EnableAutoConfiguration@EnableConfigServerpublic class Application {    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }    }

其中@EnableConfigServer 为作为配置文件服务的注解；

appliction.yml配置文件：

server:  port: 8888spring:  cloud:    config:      enabled: true      server:        svn:          uri: http://192.168.0.66/svn/cloudconfig/          username: chenhua          password: 123456        #git:        #  uri: https://github.com/pcf-guides/configuration-server-config-repo        default-label: config  profiles:    active: subversionlogging:  levels:    org.springframework.boot.env.PropertySourcesLoader: TRACE    org.springframework.cloud.config.server: DEBUG

创建一个svn仓库作为spring cloud 的配置文件库；

这张图片中配置文件的结构写错了；

配置文件的结构应该是在客户端的配置文件appliction.preperties文件中的两个字段;(spring.cloud.config.name 和 spring.cloud.config.profile)

要符合{spring.cloud.config.name}-{spring.cloud.config.profile}.preperties 或者后缀为.yml的配置文件；

创建svn库后一定要创建一个文件夹；（必须的），不知道是是不是读取库的问题；默认情况下，他会去这你提供的svn库uri中的trunk文件夹下读取（可以配置这个文件夹的名称。配置成空默认去trunk文件夹查找配置文件），配置文件不能放到svn的根目录下（默认去trunk的文件夹下找配置文件）；

客户端工程：

客户端的工程结构：

客户端的配置文件：

<?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">    <modelVersion>4.0.0</modelVersion>    <groupId>com.honkib.springcloud</groupId>    <artifactId>spring-cloud-config-client</artifactId>    <version>1.0-SNAPSHOT</version>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.2.3.RELEASE</version>        <relativePath /> <!-- lookup parent from repository -->    </parent>        <dependencyManagement>        <dependencies>            <dependency>                <groupId>org.springframework.cloud</groupId>                <artifactId>spring-cloud-starter-parent</artifactId>                <version>1.0.1.RELEASE</version>                <type>pom</type>                <scope>import</scope>            </dependency>        </dependencies>    </dependencyManagement>    <dependencies>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-web</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-config-client</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-actuator</artifactId>        </dependency>        <dependency>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-starter-test</artifactId>            <scope>test</scope>        </dependency>        <dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-actuator</artifactId></dependency>            </dependencies>    <repositories>        <repository>            <id>spring-milestones</id>            <name>Spring Milestones</name>            <url>http://repo.spring.io/milestone</url>            <snapshots>                <enabled>false</enabled>            </snapshots>        </repository>    </repositories>    <pluginRepositories>        <pluginRepository>            <id>spring-milestones</id>            <name>Spring Milestones</name>            <url>http://repo.spring.io/milestone</url>            <snapshots>                <enabled>false</enabled>            </snapshots>        </pluginRepository>    </pluginRepositories>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>    </build></project>

appliction.java

package com.hobkib.cloud.democlient;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * Created by liaokailin on 16/4/28. */@SpringBootApplication@RestControllerpublic class Application {    @Value("${mysqldb.datasource.url:World}")    String bar;    @RequestMapping("/")    String hello() {        return "Hello " + bar + "!";    }    public static void main(String[] args) {        SpringApplication.run(Application.class, args);    }}

bootstrap.preperties 配置文件:

server.port=8081spring.cloud.config.uri=http://localhost:${config.port:8888}spring.cloud.config.name=cloud-configspring.cloud.config.profile=${config.profile:dev}spring.application.name=cloud-simple-service

这样程序就已经完成了；

接下来就是运行程序了；

先启动configserver 程序；

然后再启动client工程；

成功了的话；我们应该能在client程序的日志中看到这么一条日志：

2017-02-16 15:32:54.209 INFO 9836 --- [ main] b.c.PropertySourceBootstrapConfiguration : Located property source: CompositePropertySource [name='configService', propertySources=[MapPropertySource [name='http://192.168.0.66/svn/cloudconfig/config/cloud-config-dev.properties']]]

这就表明已经读取到日志了；

接下来只要在@Value("${key}")就可以获取到配置文件的值了；

或者好用env.getPreperty来获取配置文件信息；

注：很重要的一点；不知道的是什么问题；configserver服务端一定要用yml配置文件，使用preperties配置文件启动不成功；不识别；

还有就是注意svn的文件目录结构；配置文件名称结构
