Question

springboot maven war로 개발중입니다. &#64;Controller public class JoinController { &#64;RequestMapping(&#34;/join&#34;) public ModelAndView join(HttpServletRequest request, HttpServletResponse response)throws ServletException { ModelAndView mav &#61; new ModelAndView(&#34;/join&#34;); return mav; } }javax.servlet.ServletException: Circular view path [/join]: would dispatch back to the current handler URL [/join] again. Check your ViewResolver setup!
