每次对jsp的页页面源码请求都要将jsp转换为servlet吗？
在处理动态网页请求时，如ASP、面出码访ASP.NET、现源JSP、出现错误PHP等，访问gun源码下载每次客户端对JSP的页页面源码请求确实需要将其转换为Servlet。这是面出码访因为，JSP本质上是现源一种模板引擎，用于生成动态网页内容。出现错误它的访问源代码首先会被JSP引擎编译为Servlet，即一个Java类，页页面源码这个过程发生在服务器端。面出码访phpems系统源码Servlet作为Java的现源Web应用组件，能够执行Java代码，出现错误处理客户端请求并生成响应结果。因此，为了使JSP能够运行服务器端代码并生成动态网页内容，其源代码必须先转换为Servlet。mavenssm框架源码
当用户请求一个JSP页面时，Web服务器（如Tomcat、Jetty等）接收到请求后，会调用JSP引擎来处理该请求。JSP引擎首先解析JSP页面的HTML和脚本元素，然后将这些元素转换为一个Java类，魔兽网站源码这个过程即编译阶段。在编译过程中，JSP引擎会检查JSP页面中是否存在脚本元素，并将它们转换为Java代码。然后，这个Java类会被JVM解释执行，源码编译configure生成动态内容，并最终以HTML格式返回给客户端浏览器。
简而言之，每次对JSP的请求都要将其转换为Servlet，这是因为JSP本身不具备直接执行服务器端代码的能力。通过将JSP源代码转换为Servlet，Web服务器能够执行Java代码，处理动态请求并生成响应内容。这一过程确保了动态网页能够根据用户请求生成个性化、动态的网页内容，从而实现丰富的Web应用功能。

为什么我的网站点击之后会出现源代码或者直接下载那个ASP页面？ 感激.！
出现这个情况是因为浏览器没有识别你的网页，也就是你的asp页面没有被当成一个web页面来解析，而是作为一个文本文档，这样当然会出现下载界面了。
asp不大熟悉了，如果是jsp的话，头上有下面这句(asp也一定有对应的)
<%@page contenttype="text/html;chatset=GBK"%> 中的contentType T大写，不大写不会被浏览器识别的。"text/html"也要写对。
