Today, running eclipse and tomcat failed to start. I don't know what happened. Through investigation, it was found that one url of controller class in springmvc reported an error

Solutions:

1.web.xml has a problem

check < url-pattern > < /url-pattern > Whether the configured content is missing "/" in "/","/" indicates the current web application.

@WebFilter("/*")

2. If it is springmvc, check if there is any error in @RequestMapping (value =) in controller class
