1.定义异常控制器

@Controller
    @ControllerAdvice
    @RequestMapping("/error")
    public class ErrorController {
    
        private static final Logger logger = LoggerFactory.getLogger(ErrorController.class);
    
        public static final String DEFAULT_ERROR_VIEW = "error";
    
    
        /************** 404异常处理 ***********/
        @GetMapping("/404")
        public void error404(HttpServletResponse response){
            try {
                response.sendRedirect("/error/demo");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    
        @GetMapping("/page")
        public String error404(){
            return "/error/404";
        }
    
    
        /************** 500异常处理 ***********/
        @GetMapping("/500")
        @ExceptionHandler(value = Exception.class)
        @ResponseBody
        public Object error500(HttpServletRequest request, HttpServletResponse response, Exception e) {
            logger.debug(getClass().getName() + ".errorHandler】统一异常处理：request="+request);
            return ResultUtil.fail(500,e.getMessage());
        }
    
    
    }

2.自定义异常

public class AdminException extends RuntimeException {
    
        private Integer code;
        private String message;
    
        public AdminException(Integer code, String message) {
            super(message);
            this.code = code;
            this.message = message;
        }
    
        public AdminException(ExceptionEnum exceptionEnum) {
            super(exceptionEnum.getMsg());
            this.code = exceptionEnum.getCode();
        }
    
        public Integer getCode() {
            return code;
        }
    
        public void setCode(Integer code) {
            this.code = code;
        }
    
        @Override
        public String getMessage() {
            return message;
        }
    
        public void setMessage(String message) {
            this.message = message;
        }
    }
