一、类型一
1、自定义异常
@Data public class LeaseException extends RuntimeException { private Integer code; public LeaseException(Integer code, String message) { super(message); this.code = code; } public LeaseException(ResultCodeEnum resultCodeEnum) { super(resultCodeEnum.getMessage()); this.code = resultCodeEnum.getCode(); } }2、统一返回结果状态信息类
import lombok.Getter; /** * 统一返回结果状态信息类 */ @Getter public enum ResultCodeEnum { SUCCESS(200, "成功"), FAIL(201, "失败"), PARAM_ERROR(202, "参数不正确"), SERVICE_ERROR(203, "服务异常"), DATA_ERROR(204, "数据异常"), ILLEGAL_REQUEST(205, "非法请求"), REPEAT_SUBMIT(206, "重复提交"), DELETE_ERROR(207, "请先删除子集"), ADMIN_ACCOUNT_EXIST_ERROR(301, "账号已存在"), ADMIN_CAPTCHA_CODE_ERROR(302, "验证码错误"), ADMIN_CAPTCHA_CODE_EXPIRED(303, "验证码已过期"), ADMIN_CAPTCHA_CODE_NOT_FOUND(304, "未输入验证码"), ADMIN_LOGIN_AUTH(305, "未登陆"), ADMIN_ACCOUNT_NOT_EXIST_ERROR(306, "账号不存在"), ADMIN_ACCOUNT_ERROR(307, "用户名或密码错误"), ADMIN_ACCOUNT_DISABLED_ERROR(308, "该用户已被禁用"), ADMIN_ACCESS_FORBIDDEN(309, "无访问权限"), APP_LOGIN_AUTH(501, "未登陆"), APP_LOGIN_PHONE_EMPTY(502, "手机号码为空"), APP_LOGIN_CODE_EMPTY(503, "验证码为空"), APP_SEND_SMS_TOO_OFTEN(504, "验证法发送过于频繁"), APP_LOGIN_CODE_EXPIRED(505, "验证码已过期"), APP_LOGIN_CODE_ERROR(506, "验证码错误"), APP_ACCOUNT_DISABLED_ERROR(507, "该用户已被禁用"), TOKEN_EXPIRED(601, "token过期"), TOKEN_INVALID(602, "token非法"); private final Integer code; private final String message; ResultCodeEnum(Integer code, String message) { this.code = code; this.message = message; } }3、全局异常处理
@RestControllerAdvice public class GlobalExceptionHandler { @ExceptionHandler(Exception.class) public Result handle(Exception e) { e.printStackTrace(); return Result.fail(); } @ExceptionHandler(LeaseException.class) public Result handle(LeaseException e) { String message = e.getMessage(); Integer code = e.getCode(); e.printStackTrace(); return Result.fail(code, message); } }4、统一返回结构
import lombok.Data; /** * 全局统一返回结果类 */ @Data public class Result<T> { //返回码 private Integer code; //返回消息 private String message; //返回数据 private T data; public Result() { } private static <T> Result<T> build(T data) { Result<T> result = new Result<>(); if (data != null) result.setData(data); return result; } public static <T> Result<T> build(T body, ResultCodeEnum resultCodeEnum) { Result<T> result = build(body); result.setCode(resultCodeEnum.getCode()); result.setMessage(resultCodeEnum.getMessage()); return result; } public static <T> Result<T> ok(T data) { return build(data, ResultCodeEnum.SUCCESS); } public static <T> Result<T> ok() { return Result.ok(null); } public static <T> Result<T> fail() { return build(null, ResultCodeEnum.FAIL); } public static <T> Result<T> fail(Integer code, String message) { Result<T> result = build(null); result.setCode(code); result.setMessage(message); return result; } }持续更新……
