微服务相关概念 https://microservices.io 我们开发的仓库代码 https://github.com/bobacgo/kit 这篇文章先介绍：单个web服务常见的功能模块微服务常见的功能模块框架主要基于热门的 go pkg 进行精简封装。不追求过度设计。后续的的文章会围绕这些功能模块展开，代码设计思路。功能描述单体服务常用的模块 Http 服务（gin）配置文件管理（viper）日志设计（zap）请求参数校验、响应结果封装 (参数校验 validator/v10) 异常恢复安全模块（jwt）数据库初始 (mysql、go-redis) orm框架集成（gorm）本地缓存组件 (go-cache) http请求工具 (go-retry) 性分析接口 Swagger文档接口微服务framework 配置中心（ectd、本地）注册中心（ectd）通信方式（gRPC、http、MQ）网关服务（go service）监控中心（prometheus、grafana）链路追踪 (jaeger) 限流、熔断（rate、 ratelimt，hystrix-go）相同服务多节点任务分配（基于redis）框架使用剧透 1 2 # 下载依赖 go get github.com/bobacgo/kit 快速开始 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 package main import ( "flag" "log" "github.com/bobacgo/kit/app" "github.com/bobacgo/kit/app/conf" "github.com/bobacgo/kit/examples/config" "github.com/bobacgo/kit/examples/internal/app/router" ) var filepath = flag.String("config", "./config.yaml", "config file path") func init() { flag.String("name", "admin-service", "service name") flag.String("env", "dev", "run config context") flag.String("logger.level", "info", "logger level") flag.Int("port", 8080, "http port 8080, rpc port 9080") conf.BindPFlags() } func main() { newApp := app.New(*filepath, app.WithScanConfig(config.Cfg), app.WithLogger(), app.WithMustLocalCache(), // app.WithMustDB(), // app.WithMustRedis(), app.WithGinServer(router.Register), ) if err := newApp.Run(); err != nil { log.Panic(err.Error()) } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 go run main.go --config ./config.yaml 2025-03-06 14:00:22.870 INFO app/option.go:116 local config info basic: name: examples-service version: 1.0.0 env: dev configs: - ./deploy/v1.0.0/db.yaml - ./deploy/v1.0.0/logger.yaml - ./deploy/v1.0.0/redis.yaml registry: addr: 127.0.0.1:2379 timeout: "" server: http: addr: 0.0.0.0:8080 timeout: 1s rpc: addr: 0.0.0.0:9080 timeout: 1s security: ciphertext: isCiphertext: false cipherKey: YpC5w*****uMvd4f jwt: secret: YpC5w*****uMvd4f issuer: gogo-admin accessTokenExpired: "" refreshTokenExpired: "" cacheKeyPrefix: admin:login_token logger: level: "" timeFormat: "2006-01-02 15:04:05.000" filepath: ./logs filename: examples-service filenameSuffix: 2006-01-02-150405 fileExtension: log fileJsonEncoder: false fileSizeMax: 10 fileAgeMax: 180 fileCompress: true db: default: source: admin******tcp(127.0.0.1:3306)/mall-ums?charset=utf8mb4&parseTime=True&loc=Local dryRun: false slowThreshold: 1 maxLifeTime: 1 maxOpenConn: 100 maxIdleConn: 30 localCache: maxSize: 500MB redis: addrs: - 127.0.0.1:6379 username: "" password: "" db: 0 poolSize: 50 readTimeout: 1ms writeTimeout: 1ms service: errattemptlimit: 5 2025-03-06 14:00:22.870 INFO app/option.go:118 [config] init done. 2025-03-06 14:00:22.870 INFO app/option.go:119 [logger] init done. 2025-03-06 14:00:22.877 INFO app/option.go:132 [local_cache] init done. 2025-03-06 14:00:22.877 INFO app/service.go:95 server started [GIN-debug] [WARNING] Running in "debug" mode.
