1、基础异常类

①、编写一个 基础的异常类， 后面我们自己定义多数的异常需要继承这个基础的异常类

②、基础异常类 继承 RuntimeException 

package com.ruoyi.common.exception;
/*** 基础异常** @author ruoyi*/
public class BaseException extends RuntimeException {private static final long serialVersionUID = 1L;/*** 所属模块*/private String module;/*** 错误码*/private String code;/*** 错误码对应的参数*/private Object[] args;/*** 错误消息*/private String defaultMessage;public BaseException(String module, String code, Object[] args, String defaultMessage) {this.module = module;this.code = code;this.args = args;this.defaultMessage = defaultMessage;}public BaseException(String module, String code, Object[] args) {this(module, code, args, null);}public BaseException(String module, String defaultMessage) {this(module, null, null, defaultMessage);}public BaseException(String code, Object[] args) {this(null, code, args, null);}public BaseException(String defaultMessage) {this(null, null, null, defaultMessage);}@Overridepublic String getMessage() {String message = null;if (!StringUtils.isEmpty(code)) {message = MessageUtils.message(code, args);}if (message == null) {message = defaultMessage;}return message;}public String getModule() {return module;}public String getCode() {return code;}public Object[] getArgs() {return args;}public String getDefaultMessage() {return defaultMessage;}
}

2、用户信息异常类

package com.ruoyi.common.exception.user;
/*** 用户信息异常类** @author ruoyi*/
public class UserException extends BaseException {private static final long serialVersionUID = 1L;public UserException(String code, Object[] args) {super("user", code, args, null);}
}

3、验证码错误异常类

package com.ruoyi.common.exception.user;/*** 验证码错误异常类** @author ruoyi*/
public class CaptchaException extends UserException {private static final long serialVersionUID = 1L;public CaptchaException() {super("user.jcaptcha.error", null);}
}

4、验证码失效异常类

package com.ruoyi.common.exception.user;/*** 验证码失效异常类* * @author ruoyi*/
public class CaptchaExpireException extends UserException
{private static final long serialVersionUID = 1L;public CaptchaExpireException(){super("user.jcaptcha.expire", null);}
}

5、验证码失效异常类

package com.ruoyi.common.exception.user;/*** 验证码失效异常类** @author ruoyi*/
public class CaptchaExpireException extends UserException {private static final long serialVersionUID = 1L;public CaptchaExpireException() {super("user.jcaptcha.expire", null);}
}

6、用户密码不正确异常

package com.ruoyi.common.exception.user;/*** 用户密码不正确或不符合规范异常类** @author ruoyi*/
public class UserPasswordNotMatchException extends UserException {private static final long serialVersionUID = 1L;public UserPasswordNotMatchException() {super("user.password.not.match", null);}
}

7、自定义异常

package com.ruoyi.common.exception;/*** 自定义异常** @author ruoyi*/
public class CustomException extends RuntimeException {private static final long serialVersionUID = 1L;private Integer code;private String message;public CustomException(String message) {this.message = message;}public CustomException(String message, Integer code) {this.message = message;this.code = code;}public CustomException(String message, Throwable e) {super(message, e);this.message = message;}@Overridepublic String getMessage() {return message;}public Integer getCode() {return code;}
}
