1、逐层寻址拿到interface类型才算结束。 2、TypeOf只能拿到字段定义信息,不能拿到实际的值(本人没有找到api)。但是ValueOf却是都可以拿到。 上ValueOf路线代码,最终返回tag中json名称与实际值的map对象,方便实现插入sql的生成: func tagMatchV(bo interface{}) map[string]interface{} { val := reflect.ValueOf...

Luckily, with the use of casting, we can change the type of a variable, when necessary, without violating Go’s strong type system. Golang Type Casting Type Conversion Operators One of the common ways of converting the data types in Go is using the type conversion operators. ...

In Golang or Go, as we all know it, variables and data types are at the forefront of any code that we write. When working in a language such as Go, you may encounter such instances where we need to determine and evaluate the type of value that is stored in a given variable. This...
In Golang, thetype conversion or typecastingis used to change an entity of one data type into another. There are two types of type conversion:implicit type conversionandexplicit type conversion. The term for implicit type conversion iscoercion. Explicit type conversion in some specific way is kn...

Go语言提供了运行时反射的内置支持实现,并允许程序借助反射包来处理任意类型的对象.Golang中的reflect.TypeOf()函数用于获取代表i的动态类型的反射类型。要访问此函数,需要在程序中导入反射包。 用法: funcTypeOf(i interface{}) Type 参数:该函数仅采用interface(i)的一个参数。
