Spring Cloud Config集成SVN實踐

相信一些公司是用SVN作版本管理的，那如何使用Spring Cloud Config集成svn來作配置中心呢？

一、首先搭建一個config-server：

pom 依賴：

<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.3.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Dalston.SR1</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>
<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-server</artifactId>
		</dependency>
		<dependency>
			<groupId>org.tmatesoft.svnkit</groupId>
			<artifactId>svnkit</artifactId>
		</dependency>
		
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>
		
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-bus-amqp</artifactId>
		</dependency>

</dependencies>

bootstrap.properties：

server.port=8304
spring.application.name=test-config
eureka.client.serviceUrl.defaultZone=http://192.168.12.55:8301/eureka/

#eureka.instance.ip-address=192.168.12.21

eureka.instance.prefer-ip-address=true

#svn 配置
spring.cloud.config.server.svn.uri=https://192.168.12.50/svn/test/trunk/demo
spring.cloud.config.server.svn.username=admin
spring.cloud.config.server.svn.password=123456
spring.cloud.config.server.svn.default-label=trunk

#specific svn
spring.profiles.active=subversion
#spring.profiles.application=test-config-server

management.security.enabled=false
#spring cloud bus
spring.cloud.bus.trace.enabled=true
spring.rabbitmq.host=192.168.12.20
spring.rabbitmq.port=5672
spring.rabbitmq.username=test
spring.rabbitmq.password=123456

啓動類：

@EnableConfigServer
@EnableDiscoveryClient
@SpringBootApplication
public class ConfigServiceApplication {

	public static void main(String[] args) {

		SpringApplication.run(ConfigServiceApplication.class, args);

	}
}

注意在 svn：https://192.168.12.50/svn/test/trunk/demo 這個目錄下新建一個config-dev.properties文件：

test.name=zhangsan

 

再新建一個 config-client項目：

<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.3.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Dalston.SR1</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>
<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-config</artifactId>
		</dependency>
        <!- 必需要的哈，用於refresh-->
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-bus-amqp</artifactId>
		</dependency>

</dependencies>

application.properties：

server.port=8305
spring.application.name=test-config-client
management.security.enabled=false

# 指定此實例的ip
#eureka.instance.ip-address=192.168.12.50
# 註冊時使用ip而不是主機名
#eureka.instance.prefer-ip-address=true


#spring cloud bus
spring.rabbitmq.host=192.168.12.20
spring.rabbitmq.port=5672
spring.rabbitmq.username=test
spring.rabbitmq.password=123455

bootstrap.properties：

#對於svn的文件名
spring.cloud.config.name=config
#config-dev.properties 對於dev
spring.cloud.config.profile=dev
spring.cloud.config.label=trunk
spring.cloud.config.discovery.enabled=true
#指定config server serviceId
spring.cloud.config.discovery.serviceId=test-config
spring.cloud.bus.trace.enabled=true

#註冊中心
eureka.client.serviceUrl.defaultZone=http://192.168.12.55:8301/eureka/

編寫服務類：

/**
 * 使用@RefreshScope該註解，會在接到SpringCloud配置中心配置刷新的時候自動將新的配置更新到該類對應的字段中
 */
@RestController
@RefreshScope
public class HelloController {

    @Value("${test.name}")
    private String testName;

    @RequestMapping("/hello")
    public String index(@RequestParam String name) {
	   return "hello " + name + "， Config test.name:" + testName;
    }

}


@SpringBootApplication
@EnableDiscoveryClient
public class ConfigClientApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(ConfigClientApplication.class, args);
    }

}

啓動項目：

訪問：http://localhost:8305/hello?name=tim 就會正常顯示：

hello tim， Config test.name: zhangsan

當修改svn文件提交後，以post請求訪問：http://localhost:8305/refresh  就會獲取到最新配置信息了。
