搞定了第一个微服务后，第二个微服务开发起来自然轻车熟路。

代码初始化

---

执行以下命令，建立名为word的服务，同样保存在app目录下。

$ gf init app/word -a
initializing...
initialization done! 
you can now run "cd app/word && gf run main.go" to start your journey, enjoy!

如法炮制，删除下列文件，留下一个空白的环境。

app/word/api/*
app/word/internal/controller/*
app/word/internal/cmd/cmd.go

进入微服务仓库，开始正式开发。

$ cd app/word

生成数据模型

---

建立数据表

在word数据库下，执行SQL语句，建立保存用户数据的表：

CREATE TABLE `words` (
    id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
    uid INT UNSIGNED NOT NULL,
    word VARCHAR ( 255 ) NOT NULL,
    definition TEXT,
    example_sentence TEXT,
    chinese_translation VARCHAR ( 255 ),
    pronunciation VARCHAR ( 255 ),
    created_at DATETIME,
    updated_at DATETIME
);

生成dao模型

app/user/hack/config.yaml

gfcli:  
  gen:  
    dao:  
      - link: "mysql:root:12345678@tcp(srv.com:3306)/word"  
        descriptionTag: true

$ gf gen dao
generated: D:\project\proxima\app\word\internal\dao\words.go
generated: D:\project\proxima\app\word\internal\dao\internal\words.go
generated: D:\project\proxima\app\word\internal\model\do\words.go
generated: D:\project\proxima\app\word\internal\model\entity\words.go
done!

生成pbentity模型

app/user/hack/config.yaml

gfcli:
  gen:  
    dao:  
      - link: "mysql:root:12345678@tcp(srv.com:3306)/word"  
        descriptionTag: true  
  
    pbentity:  
      - link: "mysql:root:12345678@tcp(srv.com:3306)/word"

$ gf gen pbentity
generated: D:\project\proxima\app\word\manifest\protobuf\pbentity\words.proto
done!
