Is there a way to store Thymeleaf templates not in resources or webapp, but in the same packages as classes instead? For example structure like this:
com
example
myapp
foo
Foo.class
Template.html
bar
Bar.class
Template.html
OtherTemplate.html
How would I have to configure Spring and Thymeleaf in order to achieve this?
You need to define a ClassLoaderTemplateResolver in the WebMvcConfigurer.
In the following example, the base package where I have my templates is net.yadaframework.views (which whould be com.example.myapp in your case).
When I return a view from a Controller, the path is relative to that package, so "/foo/Template" in your example.
The patterns Set should contain the subfolders of the base package, so "/foo/*" and "/bar/*" in your example.
@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;
}
