优化自定义的Exception的日志打印，设置自定义使用的ApiException extends Exception日志打印不刷出堆栈信息配置代码ApiException类即可

# 1、ApiException extends Exception类的定义实现 #

public class ApiException extends Exception  {
    
        private static final long serialVersionUID = 1256016620875694495L;
    
        private int code;
    
        private String msg;
    
        public ApiException(int code, String msg){
            super(msg);
            this.code = code;
            this.msg = msg;
        }
    
        public int getCode() {
            return code;
        }
    
        public void setCode(int code) {
            this.code = code;
        }
    
        public String getMsg() {
            return msg;
        }
    
        public void setMsg(String msg) {
            this.msg = msg;
        }
        // 关键
        @Override
        public Throwable fillInStackTrace() {
            return this;
        }
    
    
    }

# 2、使用切面处理，这个仅仅针对Controller层面的切面， #

先让每一个Controller集成一个BaseController

然后使用切面对Controller进行切面处理，

public class BaseController {
    
        private String VERSION = "1.0.0";
    
        protected Object ajaxSuccess(Object data) {
            return this.ajax(data, "成功", ResultCode.SUCCESS.getCode());
        }
    
        protected Object ajaxParamError(Object data) {
            return this.ajax(data, "参数错误,请检查", ResultCode.PARAM_ERROR.getCode());
        }
    
        protected Object ajaxParamError(String msg) {
            return this.ajax(null, msg, ResultCode.PARAM_ERROR.getCode());
        }
    
        protected Object ajaxInternalError(String msg) {
            return this.ajax(null, msg, ResultCode.INTERNAL_ERROR.getCode());
        }
    
        protected Object ajaxAuthError() {
            return this.ajax(null, ResultCode.API_TOKEN_ERROR.getMsg(),
                ResultCode.API_TOKEN_ERROR.getCode());
        }
    
        protected Object ajaxNotLoginError() {
            return this.ajax(null, ResultCode.NOT_LOGIN.getMsg(),
                ResultCode.NOT_LOGIN.getCode());
        }
    
        protected Object ajaxTokenError() {
            return this.ajax(null, ResultCode.API_TOKEN_ERROR.getMsg(),
                ResultCode.API_TOKEN_ERROR.getCode());
        }
    
        protected Object ajaxUnknownError(String msg) {
            if (StringUtils.isBlank(msg)) {
                msg = ResultCode.UNKNOWN_ERROR.getMsg();
            }
            return this.ajax(null, msg, ResultCode.UNKNOWN_ERROR.getCode());
        }
    
        protected Object ajax(Object data, String msg, int status) {
            BaseOut out = new BaseOut();
            out.setStatus(status);
            out.setMsg(msg);
            out.setData(data);
            out.setVersion(this.VERSION);
            return out;
        }
    
        protected Object sendError(BindingResult... results) {
            return this.ajax(null, getErrors(results),
                ResultCode.PARAM_ERROR.getCode());
        }
    
        protected String getErrors(BindingResult[] results) {
            StringBuffer str = new StringBuffer();
            for (int i = 0; i < results.length; i++) {
                BindingResult result = results[i];
                if (result.hasErrors()) {
                    List<FieldError> errors = result.getFieldErrors();
                    for (int j = 0; j < errors.size(); j++) {
                        String mm = errors.get(j).getDefaultMessage();
                        str.append(",").append(mm);
                    }
                }
            }
            return str.toString().replaceFirst(",", "");
        }

里面统一的错误配置：

public enum ResultCode {
    
        SUCCESS(1, "success"),
    
        YU_LOGIN_ERROR(400, "用户名或密码错误"),
    
        PARAM_ERROR(1001, "参数错误"),
    
        INTERNAL_ERROR(1002, "内部错误"),
    
        OPERATION_ERROR(1003, "操作异常"),
    
        
    
        SYS_ERROR(-1, "系统繁忙"),
    
        UNKNOWN_ERROR(9999, "未知错误"),
    
        SIZE_EXCEED(1020, "文件过大");
    
        private int code;
    
        private String msg;
    
        public int getCode() {
            return code;
        }
    
        public void setCode(int code) {
            this.code = code;
        }
    
        public String getMsg() {
            return msg;
        }
    
        public void setMsg(String msg) {
            this.msg = msg;
        }
    
        ResultCode(int code, String msg) {
            this.code = code;
            this.msg = msg;
        }
    }

最近的全局异常进行处理，统一的进行异常捕捉进行处理，可以进行个性化的日志输出，因为log里面的异常处理会输出堆栈信息。在这里直接处理之后也是可以的进行个性化输出！

@ControllerAdvice
    @Slf4j
    public class GlobalExceptionHandler extends BaseController {
    
        @ExceptionHandler(value = Exception.class)
        @ResponseBody
        public Object handle(Exception e, HttpServletRequest request, HttpServletResponse response) {
            if (e instanceof ParameterException) {
                log.error("参数异常", e);
                return this.ajaxParamError(StringUtils.isBlank(e.getMessage()) ? "参数异常" : e.getMessage());
            } else if (e instanceof OperationException) {
                log.error("操作异常", e);
                return this.ajax(null, e.getMessage(), ResultCode.OPERATION_ERROR.getCode());
            } else if (e instanceof MaxUploadSizeExceededException) {
                log.error("上传文件过大", e);
                return this.ajax(null, e.getMessage(), ResultCode.SIZE_EXCEED.getCode());
            } else if (e instanceof RequestThreeSystemException) {
                return this.ajaxUnknownError(e.getMessage());
            } else if (e instanceof ConstraintViolationException) {
                ConstraintViolationException exs = (ConstraintViolationException) e;
                Set<ConstraintViolation<?>> violations = exs.getConstraintViolations();
                for (ConstraintViolation<?> item : violations) {
                    System.out.println(item.getMessage());
                    return this.ajaxParamError(item.getMessage());
                }
                return this.ajaxParamError("参数异常");
            } else if (e instanceof AuthTokenException) {
                return this.ajaxTokenError();
            } else if (e instanceof ApiException) {
                log.error("业务异常：", e.getMessage());
                return e;
            } else {
                log.error("未知异常", e);
                return this.ajaxInternalError("系统内部错误");
            }
        }
    }

上面俩种办法都是可以解决这个问题的！
