top.tangyh.basic.database.plugins.MultiTenantLineInnerInterceptor

所有已实现的接口:

com.baomidou.mybatisplus.extension.plugins.inner.InnerInterceptor

public class MultiTenantLineInnerInterceptor
extends com.baomidou.mybatisplus.extension.parser.JsqlParserSupport
implements com.baomidou.mybatisplus.extension.plugins.inner.InnerInterceptor

COLUMN 级别多租户拦截器 相对于mybatis-plus 的 TenantLineInnerInterceptor，本插件支持： 1. select 语句 where条件拼接多个租户id （tenant_id in (1，2，3，4)） 2. insert、update、 delete 时，不传递租户id，则不拼接
