MyBatis Plus Batch Update Status Guide

MyBatis Plus offers a method for batch updating statuses, namely updateBatchById. This method can take a collection of entity objects as a parameter and update each object in the collection.

The sample code is shown as follows:

List<User> userList = new ArrayList<>();
// 假设有一个包含多个 User 对象的 userList

// 设置需要更新的状态值
Integer status = 1;

// 批量更新状态
userList.forEach(user -> user.setStatus(status));
userMapper.updateBatchById(userList);

In the example above, assuming there is a userList containing multiple User objects, the collection is iterated through to set the status value of each object to 1, and then the updateBatchById method is called to perform a batch update of the status. It is important to note that the updateBatchById method requires passing in a collection of entity objects as its parameter.

Please adjust the entity objects, state values, and logic of the update operations according to your actual needs.
