# Custom Request and APIRoute class { #custom-request-and-apiroute-class }

In some cases, you may want to override the logic used by the `Request` and `APIRoute` classes.

In particular, this may be a good alternative to logic in a middleware.

For example, if you want to read or manipulate the request body before it is processed by your application.

### Plus loin avec la documentation API alternative

Et maintenant, rendez-vous sur <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.

* La documentation alternative reflétera également le nouveau paramètre de requête et le nouveau corps :

# Install to local repository
mvn install
```

### Testing
```bash
# Run all tests (JUnit 4 based)
mvn test

# Run specific test class
mvn test -Dtest=SpecificTest

# Alternative test runner
mvn surefire:test
```

### Code Quality
```bash
# Generate code coverage reports
mvn jacoco:report

# License header validation
mvn apache-rat:check

        Cell a = as[i];
        if (a != null) sum += a.value;
      }
    }
    return sum;
  }

In einigen Fällen möchten Sie möglicherweise die von den Klassen `Request` und `APIRoute` verwendete Logik überschreiben.

Das kann insbesondere eine gute Alternative zur Logik in einer Middleware sein.

Wenn Sie beispielsweise den <abbr title="Anfragekörper">Requestbody</abbr> lesen oder manipulieren möchten, bevor er von Ihrer Anwendung verarbeitet wird.
