Example 6 with TenantLineInnerInterceptor

use of com.baomidou.mybatisplus.extension.plugins.inner.TenantLineInnerInterceptor in project lamp-util by zuihou.

the class BaseMybatisConfiguration method mybatisPlusInterceptor.

/**
 * 新的分页插件,一缓和二缓遵循mybatis的规则,需要设置 MybatisConfiguration#useDeprecatedExecutor = false 避免缓存出现问题(该属性会在旧插件移除后一同移除)
 * <p>
 * 注意:
 * 如果内部插件都是使用,需要注意顺序关系,建议使用如下顺序
 * 多租户插件,动态表名插件
 * 分页插件,乐观锁插件
 * sql性能规范插件,防止全表更新与删除插件
 * 总结: 对sql进行单次改造的优先放入,不对sql进行改造的最后放入
 * <p>
 * 参考：
