当我在我的配置bean中为templateEngine执行以下代码时，仅添加了一个（第一个）（请参阅15个链模板解析器）： https://www.thymeleaf.org/doc/tutorials/3.0/usingthymeleaf.html
//full extract below /*>>><<<*/
templateEngine.addTemplateResolver(templateResolver());
templateEngine.addTemplateResolver(javascriptTemplateResolver());
其他信息：
我的问题的核心是能够在webmvc中使用HTML，Javascript和CSS并找到Thymeleaf。我应该用别的东西代替吗？如果是的话，我该怎么用！！ 一个很好的替代THYMELEAF的方法可能更好，因为我必须以这种方式为每个文件添加RequestMapping。
当前，我已经设置了要在WEB-INF /中考虑的HTML页面，并且发现它很好。我以正常方式在头中添加了一个js文件，但执行时返回500错误。 我在F12中看到正在调用“ http://localhost:8080/ajax.js”，并且为此设置了一个控制器，并单击了System.out。
如果我使用th：inline =“ javascript并在脚本标签中包含逻辑，则可以工作；如果WEB-INF /中的* .js文件中带有* .html，也可以使用。但是我应该能够组织我的文件分别以正常方式分别放在/ js / css文件夹中。
我认为问题出在第二个TemplateResolver的设置上。
@Controller
public class JavascriptController {
@RequestMapping(value = "ajax.js", method = RequestMethod.GET)
public String main(Model model) {
System.out.println("entered js controller!");
return "ajax.js";
}
}

答案 0 :(得分：0)
我找到了一种告诉SpringMVC文件位置的好方法。这是使用ResourceHandlerRegistry参见代码段完成的。 我喜欢这种方法，因为事实是我不必再为每个文件做控制器了。 在这里找到解决方案：https://memorynotfound.com/adding-static-resources-css-javascript-images-thymeleaf/ 后来我还看到Thymeleaf上有一个Spring版本和一个普通版本，我猜我在春天不支持我使用的代码。
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler(
"/webjars/**",
"/img/**",
"/css/**",
"/js/**")
.addResourceLocations(
"classpath:/META-INF/resources/webjars/",
"classpath:/WEB-INF/img/",
"classpath:/WEB-INF/css/",
"classpath:/WEB-INF/js/");
}
