+# gocommon
+
+> Go 的开发框架组件，目前集成logger,http-server,http-client,db,redis,nacos,kafka,skywaling,qconf 等框架
+
+## 使用/开发须知：
+
+1、所有的配置项的key-value都是字符串格式！使用properties 格式
+
+2、下列是各个配置属性，和例子
+
+3、不允许在master分支上直接变更开发，需要merge
+
+4、所有的API都不相互依赖，抽象出来
+
+5、全部都需要走单元测试
+
+6、提交完代码走一遍`make` 测试代码
+
+## 全局配置
+
+| key                      | default_value | desc                                       | eg          | 是否必须 |
+| ------------------------ | ------------- | ------------------------------------------ | ----------- | :------: |
+| application.env          |               | 当前的环境配置，分为：`debug|test|release` | debug       |    是    |
+| application.project_name |               | 当前的应用名称                             | go-template |    是    |
+| application.port         |               | 当前应用的端口号                           | 13058       |    是    |
+
+远程配置项：
+
+```properties
+# app
+application.env=debug
+application.project_name = go-template
+application.port = 13088
+```
+
+本地`config/env.ini`配置必须包含项，如果使用nacos的需要配置一下信息，需要根据nacos具体配置信息走
+
+```ini
+[conf]
+# file|apollo|nacos，file直接读取文件
+driver = nacos
+
+[nacos-config]
+host = 10.100.101.20:8848,10.100.103.130:8848,10.100.99.14:8848
+log_path = /data/log/go-template
+namespace_id = ed35034b-634e-4ed5-9266-d7366d389351
+user_name = nacos
+password = nacos
+data_id = go-template
+```
+
+Apollo配置中心的话：
+
+`config/env.ini`
+
+```properties
+[application]
+# env : (debug|test|release) test测试环境
+env = debug
+
+[conf]
+# file|apollo|nacos，file直接读取文件
+driver = apollo
+# apollo 定时拉取的刷新时间,单位s
+remote_refresh_interval = 30
+```
