Spring Cloud入门之Spring Cloud Config

原文链接：http://www.dubby.cn/detail.html?id=9020

Config Server

创建配置中心：

编辑demo.properties:

from=default-1.0

编辑demo-dev.properties:

from=dev-1.0

上传到远程仓库(https://gitee.com/yangzheng1994/config)：

git add .
git commit -m "add config"
git push origin master

添加依赖：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.7.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>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server</artifactId>
    </dependency>
</dependencies>
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Brixton.SR5</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

编辑application.properties:

spring.application.name=config-server
server.port=7001

spring.cloud.config.server.git.uri=https://gitee.com/yangzheng1994/config.git
spring.cloud.config.server.git.search-paths=spring_cloud_config
spring.cloud.config.server.git.username=username
spring.cloud.config.server.git.password=password

本来想用GitHub，可是在家访问有点慢，又想用oschina，可是很不凑巧，今天晚上这个网站似乎挂了，所以只有用CSDN的code了。

启动类：

@EnableConfigServer
@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        new SpringApplicationBuilder(Application.class).web(true).run(args);
    }
}

测试：

这是我更新之后截的图，所以是2.0，其实应该是1.0

Config Client

新建项目，添加依赖：

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.7.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>
</properties>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-star
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-config</artifactId>
        <version>1.1.3.RELEASE</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
    </dependency>
</dependencies>
<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Brixton.SR5</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
<repositories>
    <repository>
        <id>spring-milestones</id>
        <name>Spring Milestones</name>
        <url>https://repo.spring.io/libs-milestone</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

编辑bootstrap.properties：

spring.application.name=demo
spring.cloud.config.profile=dev
spring.cloud.config.label=master
spring.cloud.config.uri=http://localhost:7001/

server.port=7002

编辑启动类：

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        new SpringApplicationBuilder(Application.class).web(true).run(args);
    }
}

使用配置，新建一个TestController.java：

@RefreshScope
@RestController
public class TestController {

    @Value("${from}")
    private String from;

    @RequestMapping(value = "from")
    public String from() {
        return this.from;
    }
}

测试请求http://localhost:7002/from:

这是测试完之后才截的图，如果你按照本文顺序来做，应该是dev-1.0
