Thymeleaf 3 和 Tiles2 集成

Question

Thymeleaf 3 是否以某种方式支持 Tiles 2？我在 Thumeleaf 2.x.x thymeleaf-extras-tiles2-spring4 中使用了一个包，但正如我现在看到的那样，由于 org.thymeleaf.dialect.AbstractDialect class

中的更改，它不兼容

Caused by: java.lang.NoSuchMethodError: org.thymeleaf.dialect.AbstractDialect: method <init>()V not found
[INFO]  at org.thymeleaf.extras.tiles2.dialect.TilesDialect.<init>(TilesDialect.java:46)

我是否需要等待此集成的更新才能从 T3 开始？

有什么方法可以在 Thymeleaf3 中模拟 Tiles

我只将我的 Tiles 用于以下用途：

  <definition name="portal/**" template="layouts/portal">
    <put-attribute name="_head" value="/portal/{1} :: _head"/>
    <put-attribute name="content" value="/portal/{1} :: content"/>
  </definition>

Answer 1

为了解决这个问题，我为 SpringTemplateEngine 创建了一个代理并建议使用 TemplateEngine.process() 方法。

工作原理：

代码图根据模板路径布局例如：

portal/moje_konto/moje_dane

映射到布局

 LAYOUTS_PATH/portal

此外，它传递包含实际模板路径的变量 VIEW

内部布局可用于包含特定片段。非常简单的门户布局可能如下所示：

<!DOCTYPE html SYSTEM "about:legacy-compat">
<html lang="pl" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org" xmlns:sec="http://www.springframework.org/security/tags">
    <body>
       <div th:replace="${'portal/' + VIEW} :: content">Content</div>
    </body>
</html>

控制器：

@PreAuthorize("isAuthenticated()")
  @RequestMapping(value = "/", method = RequestMethod.GET)
  public String home(Model model) {

    return "portal/home/index";
  }

模板引擎:

public class LayoutTemplateEngine implements ITemplateEngine, MessageSourceAware, InitializingBean {

  private final Logger logger = Logger.getLogger(this.getClass().getName());

  private final String LAYOUTS_PATH = "layouts/";

  private final SpringTemplateEngine templateEngine = new SpringTemplateEngine();

  @Override
  public void process(TemplateSpec templateSpec, IContext context, Writer writer) {
    String template = templateSpec.getTemplate();

    logger.info("Rendering template: " + template);

    if (context instanceof WebExpressionContext) {
      int end = template.indexOf("/");
      if (end != -1) {
        // change template
        templateSpec = new TemplateSpec(LAYOUTS_PATH + template.substring(0, end), templateSpec.getTemplateSelectors(), templateSpec.getTemplateMode(), templateSpec.getTemplateResolutionAttributes());
        // add VIEW variable
        ((WebExpressionContext)context).setVariable("VIEW", template.substring(end + 1));
      }
    }

    templateEngine.process(templateSpec, context, writer);
    logger.info("Rendering finished");
  }

  public void setTemplateResolver(final ITemplateResolver templateResolver) {
    templateEngine.setTemplateResolver(templateResolver);
  }

  public void setEnableSpringELCompiler(final boolean enableSpringELCompiler) {
    templateEngine.setEnableSpringELCompiler(enableSpringELCompiler);
  }

  public void addDialect(final IDialect dialect) {
    templateEngine.addDialect(dialect);
  }

  public void addTemplateResolver(final ITemplateResolver templateResolver) {
    templateEngine.addTemplateResolver(templateResolver);
  }

  @Override
  public IEngineConfiguration getConfiguration() {
    return templateEngine.getConfiguration();
  }

  @Override
  public String process(String template, IContext context) {
    return process(new TemplateSpec(template, null, null, null), context);
  }

  @Override
  public String process(String template, Set<String> templateSelectors, IContext context) {
    return process(new TemplateSpec(template, templateSelectors, null, null), context);
  }

  @SuppressWarnings("resource")
  @Override
  public String process(TemplateSpec templateSpec, IContext context) {
    final Writer stringWriter = new FastStringWriter(100);
    process(templateSpec, context, stringWriter);
    return stringWriter.toString();
  }

  @Override
  public void process(String template, IContext context, Writer writer) {
    process(new TemplateSpec(template, null, null, null), context, writer);
  }

  @Override
  public void process(String template, Set<String> templateSelectors, IContext context, Writer writer) {
    process(new TemplateSpec(template, templateSelectors, null, null), context, writer);
  }

  @Override
  public IThrottledTemplateProcessor processThrottled(String template, IContext context) {
    return processThrottled(new TemplateSpec(template, null, null, null), context);
  }

  @Override
  public IThrottledTemplateProcessor processThrottled(String template, Set<String> templateSelectors, IContext context) {
    return processThrottled(new TemplateSpec(template, templateSelectors, null, null), context);
  }

  @Override
  public IThrottledTemplateProcessor processThrottled(TemplateSpec templateSpec, IContext context) {
    return templateEngine.processThrottled(templateSpec, context);
  }

  @Override
  public void afterPropertiesSet() throws Exception {
    templateEngine.afterPropertiesSet();
  }

  @Override
  public void setMessageSource(MessageSource messageSource) {
    templateEngine.setMessageSource(messageSource);
  }
}
