Golang“最佳实践”处理与数据库的连接 [英] Golang "Best practice" to handle connection to database

问题描述

我有一个用Go编写的web服务，目前我有这个全局包，我到处导入包含到MongoDB的连接（通过MGO），但是我不得不说这对我来说非常恶心。在Go中维护与数据源的连接的最佳做法是什么？我来自一个PHP世界，因此Global：S

I have a webservice written in Go and currently I have this Global package I import everywhere which contains the connection to MongoDB (via MGO), but I have to say that this feels very icky to me. What is the best practice of maintaining connections to datasources in Go? I come from a PHP world, hence the Global :S

推荐答案

导入导出初始化 * mgo.Session 对象作为包级变量或通过访问器/构造器。也许后者更适合传统的OOP-ists。

There is nothing wrong with importing a package which exports an initialized *mgo.Session object either as a package-level variable or through an accessor/initializer. Maybe the latter appeals better to classical "OOP-ists".
