environment layer is delegated for processing. Environment layer: In action, process a synchronous message or asynchronous message, cast the domain object of the domain layer into the appropriate role, and let role interact to complete the business logic. Domain layer: Includes not only the modeling of domain objects and their relationships, but also the explicit modeling of role roles of objects. Basic implementation layer: provides common technical capabilities for other tiers, such

variables to assign values, need two equal signs, such as I=3, j=4, but in go can be directly written: ij34 Very easy. Suppose you want to exchange the value of a i,j, and you just need to write: i , j = j, i //这就是go创新的地方 The initialization of variables is similar to the assignment of variables. Just give the assignment directly at the time of the variable declaration, and support three types of initialization in Golang: var variable variable

The type is described in the Golang document: Named types, with type names such as int, int64, float, string, bool. There are also custom named types.Non-named type, no type name []string, map[string]string, [4]int. When comparing two named types, the type name must be the same; when comparing named and unnamed types, the underlying type is the same. There are several forms of declaring variables:var a int//declaring a variable of type int var b st
