Java系统操作日志之数据修改变化记录-编程知识

系统操作日志之数据修改变化记录

- 前言
- 效果图
- 如何实现
- 总结

相信大家在自己的系统中都有记录日志吧，像登录日志、操作日志等等
但是一般来说，大家都是获取操作了什么东西，包括它的参数，模块等等，但是你有关心过他的数据变化吗？

前言

如果你想优雅的设计操作日志模块，请参考美团设计的操作日志模块
真的，阅读后感觉，优雅、实在是优雅至极。

效果图

在这里插入图片描述

如何实现

毋庸置疑，肯定需要两次查询，不然你怎么得到前后的数据呢？
你可以在修改前进行查询一次数据，然后再修改后查询数据，当然你是用切面的话当我没说！

这里给大家看下如何比对两次数据的变化，可以通过map来实现，上代码！

    @Asyncpublic String getPayInfoMapDiff(Map<String, ?> oldMap, Map<String, ?> newMap) {// 返回结果StringBuilder result = new StringBuilder();// 可以先判断key的总数是否相同,判断是删除了，还是新增了if (oldMap.size() > newMap.size()) {// 删除，找到少了哪些Set<String> diffKey = oldMap.keySet().stream().filter(s -> !newMap.containsKey(s)).collect(Collectors.toSet());} else {// 新增，增加了哪些Set<String> diffKey = newMap.keySet().stream().filter(s -> !oldMap.containsKey(s)).collect(Collectors.toSet());for (String key : diffKey) {Map<String, Object> value = JSON.parseObject(JSON.toJSONString(newMap.get(key)), Map.class);String context = "";if (value.get("paymentSingleMinCap") != null) {context += String.format(I18nUtil.get("insert.info.log"), I18nUtil.get("paymentSingleMinCap"), value.getOrDefault("paymentSingleMinCap", ""));context += String.format(I18nUtil.get("insert.info.log"), I18nUtil.get("paymentSingleMaxCap"), value.getOrDefault("paymentSingleMaxCap", ""));context += String.format(I18nUtil.get("insert.info.log"), I18nUtil.get("paymentTotalCap"), value.getOrDefault("paymentTotalCap", ""));}context += String.format(I18nUtil.get("insert.info.log"), I18nUtil.get("acitve.status"), value.getOrDefault("active", "").equals(1) ?
