mybatisplus批量更新方法

mybatis-plus提供了两种方式来实现批量更新操作。第一种方式是使用`saveOrUpdateBatch`方法，这个方法可以同时插入或者更新多条数据。第二种方式是通过继承`com.baomidou.mybatisplus.extension.service.impl.ServiceImpl`类来实现批量更新操作。在这个类中，有一个`updateBatchById`方法可以用于批量更新数据。这两种方式都可以根据需要选择来进行批量更新操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
