如何使用servlet过滤器来更改传入的servlet请求URL
web.xml
至
web.xml
？
更新：根据BalusC的以下步骤，我想出了以下代码：
public class UrlRewriteFilter implements Filter {
@Override
public void init(FilterConfig config) throws ServletException {
//
}
@Override
public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws ServletException, IOException {
HttpServletRequest request = (HttpServletRequest) req;
String requestURI = request.getRequestURI();
if (requestURI.startsWith("/Check_License/Dir_My_App/")) {
String toReplace = requestURI.substring(requestURI.indexOf("/Dir_My_App"), requestURI.lastIndexOf("/") + 1);
String newURI = requestURI.replace(toReplace, "?Contact_Id=");
req.getRequestDispatcher(newURI).forward(req, res);
} else {
chain.doFilter(req, res);
}
}
@Override
public void destroy() {
//
}
}
web.xml中的相关条目如下所示：
urlRewriteFilter
com.example.UrlRewriteFilter
urlRewriteFilter

我尝试了服务器端和客户端重定向以及预期的结果。 它起作用了，谢谢BalusC！
