Was sind ihre Vorteile? Und wie implementiert man eine hexagonale Anwendung in Java? Diese Fragen beantwortet Tom Hombergs in \u201cGet Your Hands Dirty on Clean Architecture\u201d.<\/p>\n        <p>Der Autor beschreibt zun\u00e4chst die Probleme der klassischen Schichtenarchitektur und erkl\u00e4rt, wie die von Robert C. Martin beschriebene \u201cClean Architecture\u201d und die von Alistair Cockburn eingef\u00fchrte (prinzipiell vergleichbare) \u201cHexagonale Architektur\u201d die Anforderungen einer modernen Anwendung (Wartbarkeit, Anpassbarkeit, Erweiterbarkeit) besser erf\u00fcllen k\u00f6nnen \u2013 n\u00e4mlich indem sie die fachliche Dom\u00e4ne (und nicht technische Details) in den Mittelpunkt der Architektur stellen.<\/p>\n        <p>Nach kurzer Theorie folgt die Praxis: Schritt f\u00fcr Schritt entwickelt der Autor eine beispielhafte Java-Anwendung mit Entities, Use Cases, Ports und Adaptern. F\u00fcr die Adapter stellt er verschiedene Mapping-Strategien vor und bespricht deren Vor- und Nachteile.<\/p>\n        <p>Er geht detailliert auf den Schnitt und die Testbarkeit der Komponenten ein und schl\u00e4gt eine Paketstruktur vor, die den Architekturstil sichtbar macht.<\/p>\n        <p>Nachdem alle Komponenten der Anwendung fertiggestellt sind, zeigt der Autor, wie diese \u2013 zum einen mit reinem Java und zum anderen mit dem Spring Framework \u2013 zusammengesetzt werden k\u00f6nnen. Damit demonstriert er eindrucksvoll, dass auch die Umsetzung der Dependency Injection blo\u00df ein austauschbares Detail der Software sein kann.<\/p>\n        <p>Anschlie\u00dfend zeigt der Autor, wie die Anwendung mit separaten Build-Artefakten, z. B. Maven-Modulen, so modularisiert werden kann, dass der Architekturstil nicht ohne weiteres umgangen werden kann. Leider geht der Autor nicht darauf ein, inwieweit das Java-Modulsystem diese Aufgabe ebenfalls \u00fcbernehmen k\u00f6nnte.<\/p>\n        <p>Schlie\u00dflich er\u00f6rtert er noch, welche Abk\u00fcrzungen wir beim Mapping zwischen den Schichten einschlagen k\u00f6nnen und welchen technischen Schulden wir uns dabei bewusst sein m\u00fcssen.<\/p>\n        <p>Das Buch ist hervorragend strukturiert und durchgehend verst\u00e4ndlich und pr\u00e4zise formuliert. Dem Autor ist es gelungen, auf nur 138 Seiten unterzubringen, was in \"Designing Hexagonal Architecture with Java\" (ein Buch, das ich nicht empfehle und das ich deshalb hier auch nicht aufliste) mehr als den vierfachen Platz einnimmt. Eine hervorragende Leistung!<\/p>\n        <p>\ud83c\udfa7 <em>Geeignet als H\u00f6rbuch?
