自己动手做框架—MVC+Front Controller

阅读更多关于自己动手做框架—MVC+Front Controller

在我前面一篇博文《逃脱Asp.Net MVC框架的枷锁,使用Razor视图引擎》发表之后,很多人关心,脱离了之后怎么办?那么这可以说是它的续篇了。同时，这也是 eLiteWeb 开源软件的一部分。 MVC + Front Controller 我们常常提到的MVC中作为Controller的C。其实有两项任务,一个是处理Http请求，另一个是对请求中的用户数据进行的处理。前者，有：安全认证,Url映射等。Front Controller 模式就是把这个C进一步分离。两个责任两个类(单一责任原则）。因此，这里给我的MVC模式,赋予新的内涵C => Command，以诠释两个模式的融合。非我族类,拒之门外 --- 转换器BasicHttphandler 这是一个Adapter目的就是为了把ASP.Net环境转化为我自定义的Web抽象。首先就是BasicHttphandler本身实现了IHttpHandler，并在Web.config中设置为默认的系统HttpHandler，把控制权拿了过来，我的世界我做主。其次,把HttpContext转换为自定义的WebRequest,然后传递给Front Controller作进一步的处理处理。 public class BasicHttpHandler:IHttpHandler { public class

@Controller和@RestController的区别

【推荐阅读】微服务还能火多久？>>> 4.0重要的一个新的改进是@RestController注解，它继承自@Controller注解。4.0之前的版本，Spring MVC的组件都使用@Controller来标识当前类是一个控制器servlet。使用这个特性，我们可以开发REST服务的时候不需要使用@Controller而使用专门的@RestController。当你实现一个RESTful web services的时候，response将一直通过response body（即字符串）发送。为了简化开发，Spring 4.0提供了一个专门版本的controller。官方文档解释： @RestController is a stereotype annotation that combines @ResponseBody and @Controller. 意思是： @RestController注解相当于@ResponseBody ＋ @Controller合在一起的作用。 1) 如果只是使用@RestController，则方法无法返回jsp页面，配置的视图解析器InternalResourceViewResolver不起作用，返回的内容就是Return 里的内容，一般为JSON。例如：本来应该到success.jsp页面的，则返回的就是“success”字符串了. 2)

本文不对Kubernetes做过多介绍，直接讲Kubernetes的各种YAML基本撰写规范。基本概念请见： http://www.infoq.com/cn/articles/Kubernetes-system-architecture-introduction 所有的Resource的定义文档在这里都有 http://kubernetes.io/v1.0/docs/api-reference/definitions.html 例如：你要查询Pod声明里面有哪些字段，那么很有用. 不多废话。 1. 创建Container / Pod## Kubernetes的编排基本单元是Pod，故而哪怕你只有一个Container，也要创建一个Pod来容纳这个Container. apiVersion: v1 kind: Pod metadata: name: hello-world # pod资源名称，集群unique的 spec: # specification of the pod’s contents restartPolicy: Never # 运行这个容器一次，然后就结束这个pod containers: - name: hello # 只是这个container的nickname image: "ubuntu:14.04" # image 名, 默认使用Docker Hub

问题 I usually use something like: class User extends CI_Controller { public function save() { if($this->input->is_post()) { //my own method ...... } } } Is there any other way, eg. in Slim framework: post("/user/save", function() { ...... }); or in .Net MVC: [HttpPost] public ActionResult save(User model) { ...... } Or can CodeIgniter handle this in its route config file?

问题 When I start my application my transparent javafx.stage.Stage shows a half transparent image as expected. But after a second stage is loaded the first stage loses its transparency.

I'm using JavaFX with JavaSE-1.8 in eclipse neon.2 on macOS Sierra. Main class package customPackage.main; import javafx.animation.FadeTransition; import
