在Dockerfile中临时执行go mod init。在实际项目中，通常已在代码仓库中维护好go.mod和go.sum文件。推荐的Dockerfile写法是先拷贝这两个文件并执行go mod download以利用Docker层缓存，再拷贝源码并构建： COPY go.mod go.sum ./ RUN go mod download COPY . . RUN go build -o app .

to the gorm directory: cd gorm The structure of this directory is as follows: Makefile go.mod go.sum gorm.go gorm.go is the main body of the gorm. Compared with go-sql-driver/mysql, GORM avoids differences cd sqldriver The structure of this directory is as follows: . — Makefile — dao.go — go.mod — go.sum — sql — dbinit.sql — sql.go — sqldriver.go You can find initialization statements for the table
