SpringCloudConfig配置中心

配置中心

使用 git 注册中心 rabbitmq消息总线 webhooks

一.创建注册中心：同前

二.配置服务端

1.Maven依赖

        
            org.springframework.cloud
            spring-cloud-config-server
        
        
            org.springframework.cloud
            spring-cloud-starter-eureka
        
        
            org.springframework.cloud
            spring-cloud-starter-bus-amqp
        

2.配置文件

#基础配置
spring.application.name=weather-config-server
server.port=8002
eureka.client.service-url.defaultZone=http://localhost:8000/eureka/
#Config
spring.cloud.config.server.git.uri=https://github.com/mianjuhou/SpringCloudDemo2
spring.cloud.config.server.git.search-paths=config-repo
[email protected]
spring.cloud.config.server.git.password=fdaMJH0318
spring.cloud.config.server.git.skip-ssl-validation=true
#RabbitMQ
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

3.启动类添加注解

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

三.配置客户端

1.Maven依赖

        
            org.springframework.cloud
            spring-cloud-starter-config
        
        
            org.springframework.cloud
            spring-cloud-starter-eureka
        
        
            org.springframework.cloud
            spring-cloud-starter-bus-amqp
        

2.配置文件
//bootstrap.properties

#基础配置
eureka.client.service-url.defaultZone=http://localhost:8000/eureka/
#Config配置
spring.cloud.config.name=neo-config
spring.cloud.config.profile=dev
spring.cloud.config.label=master
spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.serviceId=weather-config-server
spring.cloud.config.server.git.skip-ssl-validation=true

//application.properties

#基础配置
spring.application.name=config-client
server.port=9005
#总线配置
spring.cloud.bus.trace.enabled=true
#Rabbitmq配置
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

3.启动类注解

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

4.Controller注解和使用配置变量

//@RefreshScope允许内部总线刷新
//@Value("${neo.hello}")获取远程配置值
@RestController
@RefreshScope
public class HelloController {

    @Value("${neo.hello}")
    private String hello;

    @RequestMapping("/hello")
    public String from() {
        return this.hello;
    }
}

四.启动rabbitmq

rabbitmq-server

五.测试URL

//POST方法
http://localhost:8040/bus/refresh

配置

创建一个SpringCloudDemo2工程
工程下创建一个config-repo目录
目录下创建三个文件：neo-config-dev.properties,neo-config-pro.properties,neo-config-test.properties
每个文件中有一个名字为neo.hello的属性

2.0之后测试时特别注意

用
spring.cloud.config.server.git.skip-ssl-validation=true
代替
management.security.enabled=false
