1.定義異常控制器

@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異常處理 ***********/
    @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異常處理 ***********/
    @GetMapping("/500")
    @ExceptionHandler(value = Exception.class)
    @ResponseBody
    public Object error500(HttpServletRequest request, HttpServletResponse response, Exception e) {
        logger.debug(getClass().getName() + ".errorHandler】統一異常處理：request="+request);
        return ResultUtil.fail(500,e.getMessage());
    }


}

 

2.自定義異常

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;
    }
}
