MyBatis does not have built-in support for metaobjecthandler permission control. However, you can implement your own permission control logic by extending the MetaObjectHandler interface and overriding its methods to check for permissions before performing any operations on meta objects.

You can implement your permission control logic in the insertFill, updateFill, and deleteFill methods of the MetaObjectHandler interface. In these methods, you can check the user’s permissions and only perform the operation if the user has the necessary permissions.

Here is an example of how you can implement permission control in a custom MetaObjectHandler:

public class CustomMetaObjectHandler implements MetaObjectHandler {
    @Override
    public void insertFill(MetaObject metaObject) {
        // Check user permissions before inserting data
        if (hasInsertPermission()) {
            // Perform insert operation
        }
    }

    @Override
    public void updateFill(MetaObject metaObject) {
        // Check user permissions before updating data
        if (hasUpdatePermission()) {
            // Perform update operation
        }
    }

    @Override
    public void deleteFill(MetaObject metaObject) {
        // Check user permissions before deleting data
        if (hasDeletePermission()) {
            // Perform delete operation
        }
    }

    private boolean hasInsertPermission() {
        // Implement logic to check user permissions for insert operation
    }

    private boolean hasUpdatePermission() {
        // Implement logic to check user permissions for update operation
    }

    private boolean hasDeletePermission() {
        // Implement logic to check user permissions for delete operation
    }
}

You can then configure MyBatis to use your custom MetaObjectHandler by adding it to the configuration:

SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(configuration);
configuration.addMetaObjectHandler(new CustomMetaObjectHandler());

By implementing your own permission control logic in a custom MetaObjectHandler, you can control access to meta objects based on user permissions in MyBatis.
