Thymeleaf 3和Tiles2集成 [英] Thymeleaf 3 and Tiles2 integration
问题描述
Thymeleaf 3是否以某种方式支持Tiles 2?我有一个用于Thumeleaf 2.x.x thymeleaf-extras-tiles2-spring4的程序包，但正如我现在所看到的，由于org.thymeleaf.dialect.AbstractDialect类的更改
Does Thymeleaf 3 support Tiles 2 somehow? There is a package that I was using for Thumeleaf 2.x.x thymeleaf-extras-tiles2-spring4 but as I see now it is not compatible because of changes in org.thymeleaf.dialect.AbstractDialect class
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?
Do I need to wait for an update of this integration to be able to start with T3?
有什么方法可以在Thymeleaf3中模拟图块
Is there any way that I can simulate Tiles in Thymeleaf3
我仅将Tiles用于类似这样的事情:
I only use my Tiles for something like this:
<definition name="portal/**" template="layouts/portal">
<put-attribute name="_head" value="/portal/{1} :: _head"/>
<put-attribute name="content" value="/portal/{1} :: content"/>
</definition>
推荐答案
为解决该问题，我创建了SpringTemplateEngine的代理并建议使用TemplateEngine.process()方法.
To solve that problem I have created a proxy for SpringTemplateEngine and advisedTemplateEngine.process() method.
工作方式:
基于模板路径的代码映射布局，例如:
The code map layouts on the basis of template path for instance:
portal/moje_konto/moje_dane
已映射到布局
LAYOUTS_PATH/portal
此外，它还会传递变量VIEW，其中包含指向实际模板的路径
Additionally, it passes variable VIEW containing a path to actual template
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:
Inside layouts it may be used to include specific fragments. Very simple portal layout may look like that:
<!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";
}
TemplateEngine:
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);
}
}
