类包中的Thymeleaf模板

Question

是否有一种方法可以将Thymeleaf模板存储在与类相同的包中而不是参考资料或webapp？例如，这样的结构：

com
   example
      myapp
         foo
            Foo.class
            Template.html
         bar
            Bar.class
            Template.html
            OtherTemplate.html

为了实现这一点，我必须如何配置Spring和Thymeleaf？

您需要在webmvcconfigure中定义ClassLoaderTemplateResolver。

在下面的示例中，我的模板所在的基本包是net。yadaframework。视图（在您的情况下，应该是com.example.myapp）。当我从控制器返回视图时，路径是相对于该包的，因此在您的示例中，“/foo/Template”。patterns集合应该包含基本包的子文件夹，因此在您的示例中，“/foo/*”和“/bar/*”。

@EnableWebMvc
@ComponentScan(basePackages = { "net.yadaframework.views" })
public class YadaWebConfig implements WebMvcConfigurer {

    public ClassLoaderTemplateResolver yadaTemplateResolver() {
        ClassLoaderTemplateResolver resolver = new ClassLoaderTemplateResolver();
        resolver.setPrefix("net/yadaframework/views");
        /* From the tutorial:
         When several template resolvers are applied, it is recommended to specify patterns 
         for each template resolver so that Thymeleaf can quickly discard those template resolvers 
         that are not meant to resolve the template, enhancing performance. Doing this is not a 
         requirement, but a recommendation
         */
        Set<String> patterns = new HashSet<>();
        patterns.add("/yada/*"); // Start with "yada". Patterns are NOT regexp
        patterns.add("/yadacms/*"); // Start with "yadacms". Patterns are NOT regexp
        resolver.setResolvablePatterns(patterns);
        resolver.setSuffix(".html");
        resolver.setCharacterEncoding("UTF-8");
        resolver.setTemplateMode(TemplateMode.HTML);
        resolver.setCacheable(true);
        resolver.setOrder(10); 
        return resolver;
    }
