gin framework to implement a simple project ③

To undertake: Gin frame package own routing ②

For a project, the need to separate the various functional modules, so-called three-tier model, introduce personal approach here:

contorller responsible for routing

Data model is mainly responsible for program input and output

service is mainly responsible for data processing

Utils common method is mainly responsible for storage, such as a database connection

code show as below:

project->index.go

package main

import (
    c "project/controller"

    "github.com/gin-gonic/gin"
)

func main() {
    r := gin.Default()
    rr := c.GinRouter(r)

    // listening and start the service on 0.0.0.0:8080 
    rr.Run ( " : 8080 " )
}
