一，默认html模板不会打包到二进制文件中
如果二进制文件的当前目录下不包含html模板文件路径，会报错如下
$ ./mediabank
[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.- using env: export GIN_MODE=release- using code: gin.SetMode(gin.ReleaseMode)[GIN-debug] GET /static/*filepath --> github.com/gin-gonic/gin.(*RouterGroup).createStaticHandler.func1 (3 handlers)
[GIN-debug] HEAD /static/*filepath --> github.com/gin-gonic/gin.(*RouterGroup).createStaticHandler.func1 (3 handlers)

main.main()/data/goapp/mediabank/main.go:10 +0x13二，用打包到二进制文件中
代码
main
package mainimport ("embed""mediabank/routes"
)// 嵌入文件只能为源码文件同级目录和子目录下的文件
//go:embed static/* templates/*
var embedFs embed.FS// 入口函数
func main() {//引入路由r := routes.Routes(embedFs)//runr.Run(":8080")
}route
package routesimport ("embed""github.com/gin-gonic/gin""html/template""io/fs""mediabank/controller""net/http"
)func Routes(embedFs embed.FS) *gin.Engine {router := gin.Default()//1, 加载模板文件tmpl := template.Must(template.New("").ParseFS(embedFs, "templates/**/*.html"))router.SetHTMLTemplate(tmpl)//2, 加载静态文件fp, _ := fs.Sub(embedFs, "static")router.StaticFS("/static", http.FS(fp))//3,加载favicon//static是存放favicon.ico的目录faviconHandler := http.FileServer(http.FS(fp))router.GET("/favicon.ico", func(c *gin.Context) {faviconHandler.ServeHTTP(c.Writer, c.Request)})//mediamedia := controller.NewMediaController()mediaGroup := router.Group("/media"){mediaGroup.GET("/detail", media.Detail)mediaGroup.GET("/list", media.List)mediaGroup.GET("/user", media.User)}return router
}三，运行结果:
