博客主要的路由规则如下所示：
|

```Go
|

|
||||
//显示博客首页
|

beego.Router("/", &controllers.IndexController{})
|

//查看博客详细信息
|

beego.Router("/view/:id([0-9]+)", &controllers.ViewController{})

数据库设计最简单的博客信息
|

```sql

CREATE TABLE entries (

id INT AUTO_INCREMENT,
|

title TEXT,
|

content TEXT,

created DATETIME,
|

primary key (id)
