To delete all data in a table using MyBatis Plus, you can utilize the methods provided by MyBatis Plus. You can use the delete method from the Mapper interface to accomplish this task.

Here is an example code demonstrating how to use MyBatis Plus to delete all data from a table.

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper userMapper;

    @Override
    public void deleteAllUsers() {
        userMapper.delete(null);
    }

}

In this example, we are deleting all data from the table by calling userMapper.delete(null). The parameter passed into the delete method is null, which indicates that all data in the table will be deleted.

It is important to note that deleting all data in a table is a risky operation and should be used with caution. We should make sure to backup and confirm before deleting all data in the table to prevent any unexpected situations.
