spring cloud config server 配置中心

spring cloud config  配置中心

配置中心分为  server 服务端 client 和客户端，

服务端搭建

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">    <modelVersion>4.0.0</modelVersion>    <parent> <!-- spring boot 继承 -->        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.3.5.RELEASE</version>        <relativePath /> <!-- lookup parent from repository -->    </parent>    <groupId>com.cyy</groupId>    <artifactId>my-spring-cloud-config-server</artifactId>    <version>1.0.0-SNAPSHOT</version>    <dependencyManagement>        <dependencies>            <dependency>                <groupId>org.springframework.cloud</groupId>                <artifactId>spring-cloud-dependencies</artifactId>                <version>Brixton.RELEASE</version>                <type>pom</type>                <scope>import</scope>            </dependency>        </dependencies>    </dependencyManagement>    <dependencies>        <dependency> <!-- 添加 config-server 依赖 -->            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-config-server</artifactId>        </dependency>    </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>    </build></project>

spring boot 启动类  注意spring boot 的启动类需要放到某一个包下，不能直接在 src 目录下

package app;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.config.server.EnableConfigServer;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RestController;/** * Created by Administrator on 2017/8/16. */@SpringBootApplication  @EnableConfigServer   // 配置中心服务public class ConfigSreviceApplication {    public static void main(String [] args){        SpringApplication.run(ConfigSreviceApplication.class);    }}

properties 配置

server.port=4555#git 仓库地址spring.cloud.config.server.git.uri=https://github.com/cyyinfo/spring-cloud-config-demo.git
#如果配置文件不在仓库的根目录则需要配置此项，为配置文件所在目录spring.cloud.config.server.git.search-paths=config-repository


到这里一个最简单的配置服务端搭建完成，启动后访问

http://localhost:4555/spring-cloud-config-sevice-demo/master  可以看到结果

http://localhost:4555/[git 仓库项目名称]/[profile 默认master]

client  端搭建
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">    <modelVersion>4.0.0</modelVersion>    <parent>        <groupId>org.springframework.boot</groupId>        <artifactId>spring-boot-starter-parent</artifactId>        <version>1.3.5.RELEASE</version>        <relativePath /> <!-- lookup parent from repository -->    </parent>    <groupId>com.cyy</groupId>    <artifactId>my-spring-cloud-config-client</artifactId>    <version>1.0.0-SNAPSHOT</version>    <dependencyManagement>        <dependencies>            <dependency>                <groupId>org.springframework.cloud</groupId>                <artifactId>spring-cloud-dependencies</artifactId>                <version>Brixton.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>    </dependencies>    <build>        <plugins>            <plugin>                <groupId>org.springframework.boot</groupId>                <artifactId>spring-boot-maven-plugin</artifactId>            </plugin>        </plugins>    </build></project>


启动类
package app;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 Administrator on 2017/8/16. */@RestController@SpringBootApplication@RequestMapping("/")public class ConfigClientApplication {    @Value("${test.demo.name}")    private String testDemoName;    @RequestMapping("")    public String index(){        return "config clicent testDemoName="+this.testDemoName+"#";    }    public static void main(String [] args){        SpringApplication.run(ConfigClientApplication.class);    }}


配置文件  注意是  bootstrap.properties 而不是 application.properties
spring.cloud.config.env=spring-cloud-config-sevice-demo  // git 仓库名称spring.cloud.config.profile=prev  // 配置氮气环境 决定是加载git仓库中的 application-prev.propertis haishispring.cloud.config.label=master  // git 分支名 spring.cloud.config.uri=http://localhost:4555   // 配置中心项目访问地址spring.application.name=my-config-clientserver.port=4556
