统一异常处理

一、类型一

1、自定义异常

java 复制代码

@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

java 复制代码

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

java 复制代码

@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

java 复制代码

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;
    }
}
