Printemps de Démarrage avec Apache Tuiles

J'ai mon principal mises en /src/main/webapp/WEB-INF/layouts/layouts.xml avec exemples d'entrées comme:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE tiles-definitions PUBLIC
       "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
       "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">

<tiles-definitions>

  <definition name="default" template="/WEB-INF/layouts/default.jspx">

    <put-attribute name="menu" value="/WEB-INF/views/menu.jspx"/>
    <put-attribute name="sidebar" value="/WEB-INF/views/sidebar.jspx"/>    
    <put-attribute name="header" value="/WEB-INF/views/header.jspx" />
    <put-attribute name="footer" value="/WEB-INF/views/footer.jspx" />
  </definition>

  <definition name="public" template="/WEB-INF/layouts/default.jspx"> 

    <put-attribute name="menu" value="/WEB-INF/views/menu.jspx"/>
    <put-attribute name="sidebar" value="/WEB-INF/views/sidebar.jspx"/> 
    <put-attribute name="header" value="/WEB-INF/views/header.jspx" />
    <put-attribute name="footer" value="/WEB-INF/views/footer.jspx" />
  </definition>

</tiles-definitions>

Et puis de plus en plus spécifiques des carreaux de définitions dans /src/main/webapp/WEB-INF/views/views.xml avec exemples d'entrées comme:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE tiles-definitions PUBLIC "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN" "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">
<tiles-definitions>

  <definition extends="default" name="index"> 
    <put-attribute name="body" value="/WEB-INF/views/index.jspx"/>
  </definition>

  <definition extends="public" name="login">
        <put-attribute name="sidebar" value=""></put-attribute>
        <put-attribute name="body" value="/WEB-INF/views/login.jspx"/>
    </definition>
</tiles-definitions>

Alors vous avez besoin de votre classe de configuration:

@EnableWebMvc
@Configuration
public class RootMvcConfiguration extends WebMvcConfigurerAdapter {
    ...
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {

      registry.addViewController("/").setViewName("index");
      registry.addViewController("/login").setViewName("login");
    }
    ...
}

Les haricots dans cette catégorie qui se rapportent à carreaux, tout dépend si vous souhaitez utiliser les Jsp ou Thymeleaf.

Pour les JSP, vous devriez avoir:

 @Bean 
 public UrlBasedViewResolver tilesViewResolver(){

    UrlBasedViewResolver tilesViewResolver = new UrlBasedViewResolver();
    tilesViewResolver.setViewClass(TilesView.class);
    return tilesViewResolver;
}
 @Bean
 public TilesConfigurer tilesConfigurer(){ 

    String[] definitions = new String[] {
            "/WEB-INF/layouts/layouts.xml",
            "/WEB-INF/views/**/views.xml" /*Scans directories for Tiles configurations */
            };

    TilesConfigurer tilesConfigurer = new TilesConfigurer();
    tilesConfigurer.setDefinitions(definitions);
    return tilesConfigurer;

 }

Si vous utilisez Thymeleaf vous devriez avoir quelque chose comme ça:

@Bean
public MessageSource messageSource(){

    ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
    messageSource.setBasenames("classpath:META-INF/i18n/messages");
    messageSource.setFallbackToSystemLocale(false);
    return messageSource;
}
@Bean 
public ServletContextTemplateResolver templateResolver() {
        ServletContextTemplateResolver resolver = new ServletContextTemplateResolver();
        resolver.setPrefix("/WEB-INF/");
        resolver.setSuffix(".html");
        resolver.setTemplateMode("HTML5");
        resolver.setOrder(2);
        resolver.setCacheable(false);            
        return resolver;
}

@Bean 
public SpringTemplateEngine templateEngine() throws Exception {
        SpringTemplateEngine engine = new SpringTemplateEngine();
        engine.setTemplateResolver(templateResolver());
        engine.setTemplateEngineMessageSource(messageSource());
        engine.addDialect(new TilesDialect());            
        engine.addDialect(new SpringSecurityDialect());            
        engine.afterPropertiesSet();
        return engine;
}
@Bean
public TilesConfigurer tilesConfigurer(){ 

    String[] definitions = new String[] {
            "/WEB-INF/layouts/layouts.xml",
            "/WEB-INF/views/**/views.xml" /*Scans directories for Tiles configurations */
            };

    ThymeleafTilesConfigurer tilesConfigurer = new ThymeleafTilesConfigurer();
    tilesConfigurer.setDefinitions(definitions);        
    return tilesConfigurer;

}

Alors vous pouvez étendre votre views.xml et du point de vue de noms à votre jsp ou de fichiers html et d'un exemple de contrôleur peut être comme suit:

@RequestMapping("/roles")
@Controller
public class RoleController {

    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public String show(@PathVariable("id") Integer id, Model uiModel) {
        uiModel.addAttribute("role", Role.findRole(id));
        uiModel.addAttribute("itemId", id);
        return "roles/show";
    }
}

Si vous utilisez Maven, voici quelques exemples de lib versions:

<properties>        
    <thymeleaf.version>2.0.19</thymeleaf.version>
    <thymeleaf.extras.version>2.0.0</thymeleaf.extras.version>         
    <thymeleaf.extras.security.version>2.0.0</thymeleaf.extras.security.version>
    <tiles.version>2.2.2</tiles.version>
</properties>
...

Votre définitions devraient être:

    <definition name="layout" template = "/WEB-INF/jsp/layout/layout.jsp">
    </definition>
    <definition name="home" extends="layout">
        <put-attribute name="body" value = "/WEB-INF/jsp/home.jsp" />
    </definition>
