如何从Thymeleaf调用对象的方法？ [英] How to call object's method from Thymeleaf?
问题描述
我的模板看不到从Spring传递的对象。
My template do not see objects, passed from Spring.
我的代码：
public class PublicModelAndView extends ModelAndView {
@Autowired
TemplateModulesHandler templateModulesHandler;
public void init() {
setViewName("index");
CSSProcessor cSSProcessor = new CSSProcessor();
cSSProcessor.setSiteRegion("public");
super.addObject("CSSProcessor", cSSProcessor);
JSProcessor jSProcessor = new JSProcessor();
super.addObject("JSProcessor", jSProcessor);
templateModulesHandler.setPublicModelAndView(this);
}
}
Contoller的代码：
Contoller's code:
@SpringBootApplication
@Controller
public class IndexPage {
@Autowired
PublicModelAndView publicModelAndView;
@Autowired
OurServicesBean ourServicesBean;
@Autowired
PortfolioBean portfolioBean;
@RequestMapping(value = "/", method = RequestMethod.GET)
public ModelAndView indexPage() {
publicModelAndView.setTemplate("publicSiteIndexPage");
publicModelAndView.addObject("ourServices", ourServicesBean.getMenu());
publicModelAndView.addObject("portfolioWorkTypes", portfolioBean.getWorkTypes());
publicModelAndView.addObject("portfolioWorks", portfolioBean.getWorks());
return publicModelAndView;
}
}
主模板的代码：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org"
>
<head th:include="headerAndFooter/fragments/header :: publicSiteHeader">
<title></title>
</head>
<body>
hello!
</body>
</html>
片段代码：
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org">
<head th:fragment="publicSiteHeader">
<title>SOME TITLE</title>
${CSSProcessor.setDebugCaller("Public")}
${CSSProcessor.setSiteRegion("public")}
${CSSProcessor.addCSS("/css/main.css")}
</head>
<body>
</body>
</html>
结果我看到方法调用的代码，如
As result I see code of the method calling, like
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>SOME TITLE</title>
${CSSProcessor.setDebugCaller("Public")}
${CSSProcessor.setSiteRegion("public")}
${CSSProcessor.addCSS("/css/main.css")}
为什么百万美元没有调用方法，而是在输出页面打印此文本？例如，来自 http://www.thymeleaf.org/doc/tutorials/2.1/ usingthymeleaf.html 方法调用具有相同的语法，例如
Why thymeleaf didn't call methods, but print this text at the output page? In example from http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html method calling has same syntax, like
${person.createCompleteName()}
相同的代码适用于JSP，但不适用于百里香。
The same code works good with JSP, but do not work with thymeleaf.
推荐答案
这可以通过两种方式在Thymeleaf中完成：
That can be done in Thymeleaf in two ways:
首先是使用特殊的Thymeleaf：
First is to use special for Thymeleaf:
<head th:fragment="publicSiteHeader">
<title>SOME TITLE</title>
<th:block th:text="${CSSProcessor.setDebugCaller("Public")}"/>
<th:block th:text="${CSSProcessor.setSiteRegion("public")}"/>
<th:block th:text="${CSSProcessor.addCSS("/css/main.css")}"/>
</head>
第二种方式是：
<head th:fragment="publicSiteHeader" th:inline="text">
<title>SOME TITLE</title>
[["${CSSProcessor.setDebugCaller("Public")}"]]
[["${CSSProcessor.setSiteRegion("public")}"]]
[["${CSSProcessor.addCSS("/css/main.css")}"]]
</head>
对于自然模板处理，第二选项更为可取。有关内联的更多信息，请访问： http：//www.thymeleaf。 org / doc / tutorials / 2.1 / usingthymeleaf.html #inline
For natural template processing second option is more preferable. More info about inlining can be found here: http://www.thymeleaf.org/doc/tutorials/2.1/usingthymeleaf.html#inlining
