异常日志的占位符，格式化的使用

 

logger用{}，或者用String.format("数字1：%s，和数字2：%s不一致",a,b);

 

 

例如：

 

 private void validateRequest (LedgerCalculatorRequest request) {

        List<LedgersInfoBean> ledgersInfo = request.getLedgersInfo();

        BigDecimal sumReceived = ledgersInfo.stream().map(ledgersInfoBean -> new BigDecimal(ledgersInfoBean.getReceived())).reduce(BigDecimal.ZERO, BigDecimal::add);

        BigDecimal received = new BigDecimal(request.getPaymentSubjectReceived()).add(sumReceived);

        BigDecimal totalReceived = new BigDecimal(request.getTotalReceived());

        if (received.compareTo(totalReceived) != 0) {

            log.error("已收总金额不一致,计算所得值:{},参数值:{}", received, totalReceived);

            throw new HbBusinessException("9999", String.format("已收总金额不一致,计算所得值:%s,参数值:%s", received, totalReceived));

        }

        BigDecimal totalReceivable = new BigDecimal(request.getTotalReceivable());

        BigDecimal sumReceivable = ledgersInfo.stream().map(ledgersInfoBean -> new BigDecimal(ledgersInfoBean.getReceivable())).reduce(BigDecimal.ZERO, BigDecimal::add);

        if (totalReceivable.compareTo(sumReceivable) < 0) {

            log.error("已收总金额小于分账方已收金额,分账方已收金额:{},已收总金额:{}", sumReceivable, totalReceivable);

            throw new HbBusinessException("9999", String.format("已收总金额小于分账方已收金额,分账方已收金额:%s,已收总金额:%s", sumReceivable, totalReceivable));

        }

        if (Objects.isNull(request.getPaymentSubjectReceivable())) {

            request.setPaymentSubjectReceivable(totalReceivable.subtract(sumReceivable).longValueExact());

        } else {

            BigDecimal receivable = new BigDecimal(request.getPaymentSubjectReceivable()).add(sumReceivable);

            if (receivable.compareTo(totalReceivable) != 0) {

                log.error("应收总金额不一致,计算所得值:{},参数值:{}", receivable, totalReceivable);

                throw new HbBusinessException("9999", String.format("应收总金额不一致,计算所得值:%s,参数值:%s", receivable, totalReceivable));

            }

        }

        if (Objects.isNull(request.getPlannedWithhold()))

            request.setPlannedWithhold(totalReceivable.subtract(totalReceived).longValueExact());

    }

 

 

自定义异常类：

 

 

public class HbBusinessException extends AbstractException {

 

private static final long serialVersionUID = -1895606523417907168L;

 

@Setter

@Getter

private String code;

 

@Setter

@Getter

private String message;

 

public HbBusinessException(String code, String message) {

this.code = code;

this.message = message;

}

 

public HbBusinessException(ReturnCode returnCode) {

this.code = returnCode.getCode();

this.message = returnCode.getMessage();

}

 

public HbBusinessException(Exception e) {

super(e);

}

 

}
