类 DataChangeRecorderInnerInterceptor

java.lang.Object

com.baomidou.mybatisplus.extension.plugins.inner.DataChangeRecorderInnerInterceptor

所有已实现的接口:

InnerInterceptor

public class DataChangeRecorderInnerInterceptor
extends Object
implements InnerInterceptor

数据变动记录插件 默认会生成一条log，格式： ----------------------INSERT LOG------------------------------

{ "tableName": "h2user", "operation": "insert", "recordStatus": "true", "changedData": [ { "LAST_UPDATED_DT": "null->2022-08-22 18:49:16.512", "TEST_ID": "null->1561666810058739714", "AGE": "null->THREE" } ], "cost(ms)": 0 }

* ----------------------UPDATE LOG------------------------------

{ "tableName": "h2user", "operation": "update", "recordStatus": "true", "changedData": [ { "TEST_ID": "102", "AGE": "2->THREE", "FIRSTNAME": "DOU.HAO->{\"json\":\"abc\"}", "LAST_UPDATED_DT": "null->2022-08-22 18:49:16.512" } ], "cost(ms)": 0 }
