About: solutions to CSS and other failures caused by webpage redirection Using JSP + Servlet

The main cause of the problem is that the redirection does not include all files, such as JS and CSS;

Add the following code to the JSP page to be targeted to solve the problem:

Add the following code before

<%
String Path = request. getcontextpath ();
String basepath = request. getscheme () + ": //" + request. getservername () + ":" + request. getserverport () + path + "/";
%>

Add the following line of code to the

<Base href = "<% = basepath %>">

Solve the problem.

These two lines of code are actually the code that comes with eclipse when you create a JSP page. In the future, you cannot think it is useless and delete it in disorder. I have a long memory.
