TilesConfigurer in Spring MVC

Java Config

@Configuration
@EnableWebMvc
@ComponentScan("in.groovygrails.tiles")
public class AppConfig implements WebMvcConfigurer {

    @Bean
    public TilesConfigurer tilesConfigurer() {
        TilesConfigurer c = new TilesConfigurer();
        c.setDefinitions("/WEB-INF/tiles/tiles.xml");
        c.setCheckRefresh(true);
        return c;
    }

    @Bean
    public TilesViewResolver tilesViewResolver() {
        return new TilesViewResolver();
    }
}

What Each Bean Does

• TilesConfigurer - loads definitions at startup; checkRefresh reloads XML without restart during development.
• TilesViewResolver - resolves logical view names (return "home") to Tiles definitions instead of JSP paths. Order it before any InternalResourceViewResolver.

WebAppInitializer

Register AppConfig plus DispatcherServlet mapping / in a Servlet 4 initializer - no web.xml needed, though web.xml works identically.

Key Points

• Configurer loads definitions; resolver maps view names.
• checkRefresh is for dev only - disable in production.
• One resolver for Tiles views; keep JSP resolver as fallback with higher order value.
