Java SpringBoot 捕获异常

Java SpringBoot 捕获异常

自定义异常类 JwtExceptionUtils

@Data
public class JwtExceptionUtils extends RuntimeException {

    private EnumDeclare.Code code;
    public JwtExceptionUtils(EnumDeclare.Code code, String message) {
        super(message);
        this.code = code;
    }
}

捕捉类 GlobalExceptionHandler

@ControllerAdvice
@ResponseBody
public class GlobalExceptionHandler {
    /**
     * 全局异常捕获， 处理登录失败或token失效异常
     *
     * @return
     */
    @ExceptionHandler(value = JwtExceptionUtils.class)
    public ResultDto handler(JwtExceptionUtils e) {
        return new ResultDto(e.getCode(), e.getMessage());
    }

    /**
     * 全局异常捕获
     *
     * @return
     */
    @ExceptionHandler(value = RuntimeException.class)
    public ResultDto handler2(Exception e) {
        return new ResultDto(EnumDeclare.Code.EXCEPTION, e.getMessage());
    }
}

抛出异常

throw new JwtExceptionUtils(EnumDeclare.Code.UNAUTHORIZED, "token失效，请重新登录");
