+# 代码自动生成
+gin-vue-admin提供代码自动生成功能，选择数据库表结构，可直接生成前端代码及后端代码，很方便  
+比如周报的表结构如下:  
+```
+{
+    "header":"周报",
+    "contents":[
+        {"title":"", "content":""},
+        {"title":"", "content":""}

+#### 为什么函数或方法中变量名很多都是大写字母开始的?  
 - 任何需要对外暴露的名字必须以大写字母开头，不需要对外暴露的则应该以小写字母开头。     
 但是gin-vue-admin代码中有很多大小，连方法参数都是大写字母开始的?
