mybatisplus insterbatch

MyBatis Plus provides a convenient method called "insertBatch" for inserting multiple records into a database table at once. This method is useful when you want to perform bulk inserts efficiently.

To use the "insertBatch" method in MyBatis Plus, you can follow these steps:

1. Define a list of entity objects that you want to insert.
2. Use the "insertBatch" method of the MyBatis Plus mapper interface, passing the list of entities as a parameter.

Here is an example of how you can use the "insertBatch" method:

List<User> userList = new ArrayList<>();
userList.add(new User("John", 25));
userList.add(new User("Jane", 30));

userMapper.insertBatch(userList);

In this example, we have a "User" entity class with two properties: "name" and "age". We create a list of user objects and populate it with some data. Then, we call the "insertBatch" method of the mapper interface, passing the list of user objects as a parameter.

MyBatis Plus will generate and execute an optimized SQL batch insert statement to insert all the records in one go, improving the performance compared to individual inserts.

Note that the actual implementation might vary depending on your specific setup and configuration. Make sure you have properly configured MyBatis Plus and set up the mapper interface and entity classes before using the "insertBatch" method.
