 **1. 控制器(支持FreeMarker、JSP、Velocity、JSON等等以及自定义视图渲染)**
 
 ```java
-    @Before(BlogInterceptor.class)
-    public class BlogController extends Controller {
-        public void index() {

 **2.Model(无xml、无annotaion、无attribute、无getter、无setter)**
 
 ```java
-     public class Blog extends Model<Blog> {
-        public static final Blog dao = new Blog();
-     }
+public class Blog extends Model<Blog> {
+    public static final Blog dao = new Blog();
+}
 ```
 
 **3.Validator(API引导式校验，比xml校验方便N倍，有代码检查不易出错)**
