JSP pages are usually placed under Webroot/web-inf to prevent visitors from entering the page directly.The pages under WebRoot/web-inf are protected and users cannot access them through the form of http://localhost:8080/test/webRoot/WEB-INF/content/xx.jsp, and their visits must be handled through struts.However, when the page is placed under the/web-inf, the JSP

我们知道，实现页面的跳转有两种方式，一种是通过redirect的方式，一种是通过forward的方式。redirect方式的跳转，系统会在一个新的页面打开要跳转的网页；而forward方式跳转，系统会在原来的页面上打开一个要跳转的网页。所以放到WEB-INF目录下的文件是不允许采用redirect方式的跳转来访问的X1We know that there are two ways to implement a page jump, one is through redirect, and the other is through the forward way.

Webroot and webcontent are the root folders of the program, no essential differences, the two are common and different points:Common: There is a Web-inf folder, the next file is not directly accessible;Web-inf is a secure directory, so-called security, that is, the user client can not access, only the server-side access. If you want to access it directly in the page, you need to map the file you want to access via Web. Xml. Web-inf in addition to Web.

bad", should belong to the category of robustness. Opinion two: Put to Web-inf under the JSP file, if you go directly to access this JSP is not possible, must pass the action of the jump, so you can understand why security is high, for the user is not visible, for some users, can directly access, such as, login, registration page, Can be placed directly under the Webroot, this is based on the needs of your system. Point three:
