spring cloud config 远程配置中心搭建

企业开发 2023-04-08 22:37:58 阅读次数: 0

spring cloud使用远程配置中心，可以做到不重启项目的情况下，修改的配置生效。

其中注意的事项：

      ①client服务必须加bootstrap.properties配置文件，并且不能是bootstrap.yml，并且必须把springcloud的config信息和Eureka注册中心信息配置到文件bootstrap.properties中。

      ②springcoud1.5之前的client没有security限制，但2.0后都有security登录拦截，如果想绕过登录，需要加配置信息（以下文章中会有介绍具体配置）

本文springcloud版本采用较新的2.3.7.RELEASE（Hoxton.SR9）版本

1、搭建Eurkea注册中心：

    （1）pom配置(其中主要是一如eureka-server的依赖)：   

<?xml version="1.0" encoding="UTF-8"?>

            </plugin>
        </plugins>
    </build>
</project>

  （2）yml配置文件：

spring:
  application:
    name: brilliance-eureka   

server:
  port: 8110
eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    serviceUrl:
      defaultZone: http://localhost:8110/eureka/

     （3）启动类：    

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

2、搭建config server

    （1）pom配置（主要引入config-server依赖和eureka-client依赖）：

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">

            </plugin>
        </plugins>
    </build>
</project>

   （2）、配置文件

server:
  port: 8150

# 应用名称
spring:
  security:
    user:
      name: config
      password: 123456
  application:
    name: briliance-server-config
  cloud:
    config:
      server:
        git:

#          password: yourpass
      label: master   #分支

eureka:
  client:
    register-with-eureka: true
    fetch-registry: true
    serviceUrl:
      defaultZone: http://localhost:8110/eureka/

    （3）启动类配置：

package com.brilliance.brillianceconfig;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.config.server.EnableConfigServer;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;


@EnableEurekaClient
@SpringBootApplication
@EnableConfigServer
@EnableDiscoveryClient
public class BrillianceConfigApplication {

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

}

3、搭建client config服务：

   （1）pom配置：

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">

    </dependencies>

    <dependencyManagement>
        <dependencies>
            <dependency>

            </plugin>
        </plugins>
    </build>
</project>

    （2）配置文件配置：

           ①bootstrap.properties配置：

#spring.cloud.config.name=neo-config
spring.cloud.config.name=brilianceServerConfig
spring.cloud.config.profile=dev
spring.cloud.config.label=master
#spring.cloud.config.uri=http://localhost:8150/
spring.cloud.config.discovery.enabled=true
spring.cloud.config.discovery.serviceId= briliance-server-config
spring.cloud.config.username=config
spring.cloud.config.password=123456

eureka.client.serviceUrl.defaultZone=http://localhost:8110/eureka/
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

     ②application.yml配置：

server:
  port: 8160
spring:
  application:
    name: config-client-test

   （3）启动类配置：

package com.brilliance.brillianceclientconfig;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@EnableEurekaClient
@SpringBootApplication
@EnableDiscoveryClient
public class BrillianceClientConfigApplication {

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

}

   （4）获取配置信息类接口：

package com.brilliance.brillianceclientconfig.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/index")
@RefreshScope
public class IndexController {

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

    @GetMapping("getUserInfo")
    public String getUserAge(){
        System.out.println(userAge);
        return userAge;
    }

}

  4、配置security免登陆：

package com.brilliance.brillianceclientconfig;

import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.csrf().disable()
                .authorizeRequests()
                .anyRequest().permitAll()
                .and().logout().permitAll();
    }
}

5、访问获取配置文件：

   http://localhost:8160/index/getUserInfo

修改brilianceServerConfig-dev.yml中userAge值，返回结果跟着改变
