Distributed Configuration Center: Spring Cloud Config (5) the notes

config server

Add module in spring-cloud-demo project: config-server
join rely on pom.xml file:

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-config-server</artifactId>
</dependency>

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

Increase application.properties file in the resource directory, add the following:

server.port=8888
spring.application.name=config-server

eureka.client.serviceUrl.defaultZone=http\://localhost\:8761/eureka/
spring.profiles.active=native
spring.cloud.config.server.native.searchLocations=classpath:/properties/

Create a directory under the resource directory: properties, increase the file in the directory: cloud-config-dev.properties, reads as follows

msg=hello, I'm from config-server

Create a SpringBoot project startup class in java catalog: ConfigServer, reads as follows:

/**
 * @CalssName ConfigServer
 * @Description TODO
 */
@SpringBootApplication
@EnableDiscoveryClient
@EnableConfigServer
public class ConfigServer {

    public static void main(String[] args) {
        SpringApplication.run(ConfigServer.class,args);
    }
}

config end use

Add module in spring-cloud-demo project: config-use
join rely on pom.xml file:

<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>

Increase application.properties file in the resource directory, add the following:

server.port=9802
spring.application.name=config-use
eureka.client.serviceUrl.defaultZone=http\://localhost\:8761/eureka/

spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.service-id=config-server
spring.cloud.config.name=cloud-config
spring.cloud.config.profile=${config.profile:dev}

Create a SpringBoot project startup class in java catalog: ConfigUseApplication, reads as follows:

/**
 * @CalssName ConfigUse
 * @Description TODO
 */
@SpringBootApplication
@EnableDiscoveryClient
public class ConfigUseApplication {

    public static void main(String[] args) {
        SpringApplication.run(ConfigUseApplication.class, args);
    }
}

Creating a Controller: HelloController, reads as follows:

/**
 * @CalssName HelloController
 * @Description TODO
 */
@RestController
public class HelloController {
    @Value("${msg}")
    private String msg;

    @RequestMapping("/msg")
    public String msg() {
        return msg;
    }
}

Eureka in order to start the server, config-server and config-use, browser access: http: // localhost: 9802 / msg, output is as follows:

hello, I'm from config-server
