1.新建GlobalExceptionHandler 全局异常处理类
@ControllerAdvice
@ResponseBody
public class GlobalExceptionHandler {
/**
* 处理MyException异常
*/
@ExceptionHandler(MyException.class)
public ReturnJson
return new ReturnJson
}
/**
* 处理RunTimeException异常
*/
@ExceptionHandler(RuntimeException.class)
public ReturnJson
return new ReturnJson
}
}
2.自定义异常类MyException继承RuntimeException
@Getter
public class MyException extends RuntimeException{
/*
* 状态码
*/
private int code;
/*
* 消息提示
*/
private String message;
public MyException(int code, String message) {
this.code = code;
this.message = message;
tion ex) {MT5https://www.gendan5.com/mt5.html
public MyException(ResultStatusEnum resultStatusEnum) {
this.code = resultStatusEnum.getCode();
this.message = resultStatusEnum.getMessage();
}
}
3.用到的其他类
@Data
public class ReturnJson
/*
* 状态码
*/
private int code;
/*
* 消息提示
*/
private String message;
/*
* 返回内容
*/
private T info;
public ReturnJson(int code,String message ,T info) {
this.code=code;
this.message=message;
this.info=info;
}
}
@NoArgsConstructor
@AllArgsConstructor
public enum ResultStatusEnum {
/**
* 请求成功
*/
SUCCESS(200, "请求成功！"),
/*
* 请求失败
*/
FAILURE(400, "请求失败！");
@Getter
@Setter
private int code;
@Getter
@Setter
private String message;
}
