Spring Framework

Many Java teams already use Spring Boot for building applications. Spring integration with webforJ now lets you add webforJ's UI components to existing Spring applications, or use Spring's features in new webforJ projects.

Your Spring services, repositories, and configuration work as normal. Your webforJ components can @Autowired any Spring bean. Spring Data repositories connect directly to webforJ tables through SpringDataRepository. Development gets faster with automatic browser refresh from Spring DevTools and webforJ LiveReload.

The integration keeps both frameworks doing what they do best - Spring handles backend concerns while webforJ handles the UI.

Topics

📄️ Spring Boot Setup

Spring Boot is a popular choice for building Java apps, providing dependency injection, auto-configuration, and an embedded server model. When using Spring Boot with webforJ, you can inject services, repositories, and other Spring-managed beans directly into your UI components through constructor injection.

📄️ Dependency Injection

Dependency injection (DI) is a process where objects define their dependencies through constructor arguments rather than creating or looking up dependencies themselves. The Spring container injects these dependencies when creating the object, resulting in cleaner code and better decoupling between components.

📄️ Spring Data JPA

Spring Data JPA is the de facto standard for data access in Spring applications, providing repository abstractions, query methods, and specifications for complex queries. The webforJ SpringDataRepository adapter bridges Spring Data repositories with webforJ's UI components, enabling you to bind JPA entities directly to UI components, implement dynamic filtering with JPA Specifications, and handle pagination.

📄️ Background Jobs

When users click a button to generate a report or process data, they expect the interface to remain responsive. Progress bars should animate, buttons should react to hover, and the app shouldn't freeze. Spring's @Async annotation makes this possible by moving long-running operations to background threads.

📄️ Spring DevTools

Spring DevTools provides automatic app restarts when code changes. webforJ DevTools adds automatic browser refresh - when Spring restarts your app, the browser refreshes automatically through webforJ's LiveReload server.
