JSP无法打开CSS，图像和JS [英] JSP doesn't open CSS, Images and JS

推荐答案
URL模式"/"对Web服务器具有特殊含义.它用于能够提供静态内容的默认servlet映射.静态内容是JS，CSS，图像，html资源.将这些文件定向到servlet是错误的，因为它不能提供静态内容.
The url pattern "/" has a special meaning to the web server. It's used for default servlet mapping which is capable of serving the static content. The static content is JS, CSS, images, html resources. Directing these files to your servlet is wrong, because it's not capable to serve the static content.
将servlet映射更改为@WebServlet(urlPatterns="/incidente")
Change the servlet mapping to something @WebServlet(urlPatterns="/incidente")
并使用URL localhost:8080/PainelProduct/incidente转发到jsp页面.
and use url localhost:8080/PainelProduct/incidente to forward to jsp page.
选中此问题，以了解有关servlet和servlet映射的更多信息将特定的servlet映射为Tomcat中的默认servlet .
