在本章,http请求对象使用httprequst来表示(jdk中并不存在这个类 我们自己写的),它实现了HttpServletRequest接口。 在使用的时候httprequst会被转型成HttpServletRequest,并作为servlet的service方法的参数而调用。 所以我们得设置每个httprequest实例的成员变量供servlet实例使用,需要设定的值包括uri,查询字符串,参数,Cookie...

Servlet容器有两个主要的模块,即连接器(connector)与容器(container),本文接下来创建一个连接器来增强前面文章中的应用程序的功能,以一种更优雅的方式来创建request对象和response对象;为了兼容Servlet 2.3和2.4,连接器这里创建的是javax.servlet.http.HttpServletRequest对象和javax.servlet.http.HttpServletResponse对象(ser...
因为连接器不知道servlet的类型(即它是否实现javax.servlet.Servlet,扩展javax.servlet.GenericServlet或扩展javax.servlet.http.HttpServlet),所以连接器必须始终提供HttpServletRequest和HttpServletResponse的实例。 In this chapter's application, the connector parses HTTP request headers and enables a servlet to obtai...
We’ll then create our filter, which will intercept incoming HTTP requests to log the HTTP method and URI details using theLoggingServicedependency: @ComponentpublicclassLoggingFilterimplementsFilter{@AutowiredLoggingService loggingService;@OverridepublicvoiddoFilter(ServletRequest servletRequest, ServletResponse...
In this chapter's application, the connector parses HTTP request headers and enables a servlet to obtain headers, cookies, parameter names/values, etc. You will also perfect the getWriter method in the Response class in Chapter 2 so that it will behave correctly. Thanks to these enhancements,...
Now, in order to get this whole thing to work, you'll need to make a few edits to your web.xml file. First, you need to tell the web application that Spring will be sticking its nose into the HttpServletRequest object, and through that, the HttpSession object as well. So you must...
* The HTTP request methods to map to, narrowing the primary mapping: * GET, POST, HEAD, OPTIONS, PUT, PATCH, DELETE, TRACE. * <p><b>Supported at the type level as well as at the method level!</b> * When used at the type level, all method-level mappings inherit ...
To refresh your memory, this interface is discussed in the first section of this chapter. After that, you will learn what a servlet container has to do to serve HTTP requests for a servlet. 这两个应用程序的类都属于ex02.pyrmont包。 要理解这些应用程序的工作原理,您需要熟悉javax.servlet....
