A "middleware" is a function that works with every **request** before it is processed by any specific *path operation*. And also with every **response** before returning it.

* It takes each **request** that comes to your application.
* It can then do something to that **request** or run any needed code.
* Then it passes the **request** to be processed by the rest of the application (by some *path operation*).

                new DefaultModelBuildingRequest().setValidationLevel(ModelBuildingRequest.VALIDATION_LEVEL_MAVEN_2_0);

}
