org.apache.jasperException(could not initialize class org)

Hello everyone, meet again, I'm your friend Quanstack Jun.

org.apache.jasper.JasperException:

java.lang.NullPointerException org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:542) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:370) org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:321) org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267) javax.servlet.http.HttpServlet.service(HttpServlet.java:723) org.springframework.web.filter.HiddenHttpMethodFilter.doFilterInternal(HiddenHttpMethodFilter.java:77) org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:108)

Solution: The jsp-api.jar and servlent-api.jar that come with the project are duplicated with those in tomcat, delete the two jar packages that come with the project, and then restart
