但为什么我们仍然在使用控制器? 如果您以前曾经参与过大型项目的架构编写,那么您可能已经注意到迟早会出现控制器过多的这种现象。即使您将控制器逻辑分离到各种类库或服务类中,大量的依赖项和方法以及代码的行数还是会随着时间的推移不断增长。 我来介绍一下请求处理器。这个概念很简单,但很多 PHP 开发人员都不知道。
Figure 4-3.A web application handles many requests simultaneously; all request handlers access the same services Each service has its own specification for managing concurrent access from multiple request handlers, and for the most part, a request handler doesn’t have to think about the fact that...
HTTP Request HandlersPlay abstraction for handling requests is less sophisticated in the Play Java API, when compared to its Scala counterpart. However, it may still be enough if you only need to execute some code before the controller’s action method associated to the passed request is ...

method gets the session, request, and response objects as parameters. if the handler writes a response, it must return true . this stops running other possible request handlers. otherwise, it should return false so that another handler could return a response. eventually, if no other handler ...
This package adds a handy way of creating the request handlers. Basically, the request handler is a single action controller which leads to a more clear request to the response flow. You should try to use request handlers instead of with controllers and you probably won't feel the need to ...
