導出mysql表結構生成grpc須要的proto文件工具

使用過grpc的同窗都知道，寫proto文件比較繁瑣，尤爲是寫message，對應不少字段，爲此寫了一個簡單的從mysql直接讀取表結構，生成proto文件的工具。

工具的使用很簡單，須要簡單的配置，便可運行生成proto文件。

準備

使用前需先安裝依賴包go-sql-driver/mysql

$ go get -u github.com/go-sql-driver/mysql

使用說明：

func main() {
    //模板文件存放路徑
    tpl := "d:/gopath/src/mysql-to-proto/template/proto.go.tpl"
    //生成proto文件路徑
    file := "d:/gopath/src/mysql-to-proto/sso.proto"
    //數據庫名，這裏填你本身的數據庫名
    dbName := "user"
    //配置鏈接數據庫信息
    db, err := Connect("mysql", "root:123456@tcp(127.0.0.1:3306)/"+dbName+"?charset=utf8mb4&parseTime=true")
    //Table names to be excluded
    //須要排除表，這裏的表不會生成對應的proto文件
    exclude := map[string]int{"user_log": 1}
    if err != nil {
        fmt.Println(err)
    }
    if IsFile(file) {
        fmt.Fprintf(os.Stderr, "Fatal error: ", "proto file already exist")
        return
    }
    t := Table{}
    //配置message，Cat 
    t.Message = map[string]Detail{
        "Filter": {
            Name: "Filter",
            Cat:  "custom",
            Attr: []AttrDetail{{
                TypeName: "uint64", //類型
                AttrName: "id",//字段
            }},
        },
        "Request": {
            Name: "Request",
            Cat:  "all",
        },
        "Response": {
            Name: "Response",
            Cat:  "custom",
            Attr: []AttrDetail{
                {
                    TypeName: "uint64",
                    AttrName: "id",
                },
                {
                    TypeName: "bool",
                    AttrName: "success",
                },
            },
        },
    }
    //pachage名稱
    t.PackageModels = "sso"
    //service名稱
    t.ServiceName = "Sso"
    //配置services裏面的rpc
    t.Method = map[string]MethodDetail{
        "Get":    {Request: t.Message["Filter"], Response: t.Message["Request"]},
        "Create": {Request: t.Message["Request"], Response: t.Message["Response"]},
        "Update": {Request: t.Message["Request"], Response: t.Message["Response"]},
    }
    //處理數據庫表字段屬性
    t.TableColumn(db, dbName, exclude)
    //生成proto
    t.Generate(file, tpl)
