springcloud使用nacos做注册、配置中心

环境准备

• nacos
• idea
• mysql

创建项目（引入依赖pom）

创建 bootstrap.yml

spring:
  main:
    allow-bean-definition-overriding: true
  application:
    name: gateway-manager-auth（服务名）
  cloud:
    nacos:
      ################### 注册中心 #####################
      discovery:
        server-addr: ip:8848 # 对应nacos地址
        namespace: daba22a2-228e-4e62-9418-23ec9bab8eb9 #命名空间
      ################### 配置中心 #####################
      config:
        namespace: daba22a2-228e-4e62-9418-23ec9bab8eb9 #命名空间

        file-extension: yml
        extension-configs:
         - dataId: gateway-auth.yml
           group: DEFAULT_GROUP
           refresh: true # 动态刷新

启动配置

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class AuthorizationApplication {

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

nacos上添加配置文件

启动项目

注册成功

附加swagger UI文档配置

package com.xq.vitea.gateway.auth.config.swagger;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    /**
     * 创建API应用
     * apiInfo() 增加API相关信息
     * 通过select()函数返回一个ApiSelectorBuilder实例,用来控制哪些接口暴露给Swagger来展现，
     * 本例采用指定扫描的包路径来定义指定要建立API的目录。
     *
     * @return
     */
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("包"))
                .paths(PathSelectors.any())
                .build();
    }

    /**
     * 创建该API的基本信息（这些基本信息会展现在文档页面中）
     * 访问地址：http://项目实际地址/doc.html
     *
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("网关权限")
                .description("网关权限服务")
                .termsOfServiceUrl("")
                .version("2.0")
                .build();
    }
}
