```java

    @Override
    public void audit(AuditPlutusRo ro) {
        // todo: 2024/1/24  回款相关处理

}

调用

    @Autowired
    private AuditStrategyRunner auditStrategyRunner;

    public ResultData<?> auditBack(AuditPlutusRo ro) {
        log.info("【{}】审核-业财回调处理，审核编号为：{},传入参数为：{}", ro.getAuditPlutusEnum().getName(), ro.getAuditNo(), JSON.toJSONString(ro));
        auditStrategyRunner.audit(ro.getAuditPlutusEnum(), ro);
        return ResultData.SUCCESS;
    }
