1. 스프링에서 View를 사용하는 방식은 이미 철지난 이야기이지만 그냥 붙여둔다.
2 우선 Error handler를 위한 Controller을 하나 만든다.
2-1 모든 에러는 error.jsp로 넘기고 있다.
2-2 필요하면 여기서 데이터베이스에 에러를 저장하거나 하는 작업을 한다.
package pe.pilseong.steps.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.servlet.ModelAndView;
@Controller("error")
public class ErrorController {
@ExceptionHandler(Exception.class)
public ModelAndView handleException(HttpServletRequest request, HttpServletResponse response, Exception ex) {
ModelAndView mv = new ModelAndView();
mv.addObject("exception", ex.getStackTrace());
mv.addObject("url", request.getRequestURI());
mv.setViewName("error");
return mv;
}
}
3. 사용자에게 에러를 보여주는 error.jsp 에러내용은 숨겨야 한다.
