Thymeleaf 3和Tiles2集成
Thymeleaf 3是否以某种方式支持Tiles 2?我有一个用于Thumeleaf 2.xx的程序包,thymeleaf-extras-
tiles2-spring4但正如我现在所看到的,由于org.thymeleaf.dialect.AbstractDialect
类的更改,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?
有什么方法可以模拟Thymeleaf3中的图块
我只会将Tiles用于此类情况:
<definition name="portal/**" template="layouts/portal"> <put-attribute name="_head" value="/portal/{1} :: _head"/>
<put-attribute name="content" value="/portal/{1} :: content"/>
</definition>
回答:
为了解决该问题,我创建了一个代理SpringTemplateEngine
和建议TemplateEngine.process()
方法。
基于模板路径的代码映射布局,例如:
portal/moje_konto/moje_dane
映射到布局
LAYOUTS_PATH/portal
此外,它传递变量VIEW,其中包含指向实际模板的路径
在内部布局中,它可以用来包含特定的片段。非常简单的门户布局可能看起来像这样:
<!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>
@PreAuthorize("isAuthenticated()") @RequestMapping(value = "/", method = RequestMethod.GET)
public String home(Model model) {
return "portal/home/index";
}
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

@Override
public IThrottledTemplateProcessor processThrottled(String template, IContext context) {

}
@Override

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);
}
}
