如果输入是 JSON 字符串,我们首先将其解析为map[string]interface{}格式,然后将其映射到结构中。 func jsonDecode() { var jsonStr = `{ "name": "Foo", "age": 21, "gender": "male" }` type Person struct { Name string Age int Gender string } m :=

微服务框架也是可以用于开发单体架构(monolith architecture)的应用。并且,单体应用也是最小的、最原始的、最初的项目状态,经过渐进式的开发演进,单体应用能够逐步的演变成微服务架构,并且不断的细分服务粒度。微服务框架开发的单体架构应用,既然是一个最小化的实施,
