Several template locations for Thymeleaf in Spring Boot - spring-boot

Question

Currently Spring Boot allow one value for the Thymeleaf templates location with the spring.thymeleaf.prefix property.
The default value is classpath:/templates/.
I want to have another location for the thymeleaf templates (but keep the default one), outside the jar, for example:
spring.thymeleaf.prefix = classpath:/templates/, file:/resources/templates
Do i have to define another template resolver for the new location i want ?

Answer 1

Define the setting in the application.properties file
spring.thymeleaf.templateResolverOrder=1
Now in your custom Bean which creates ITemplateResolver set order to 0 along with prefix and suffix. This way spring boot will listen to both places
Setting order to 0 is important
An example of bean creation can be
#Bean
public ClassLoaderTemplateResolver emailTemplateResolver() {
ClassLoaderTemplateResolver emailTemplateResolver = new ClassLoaderTemplateResolver();
emailTemplateResolver.setPrefix("mails/");
emailTemplateResolver.setSuffix(".html");
emailTemplateResolver.setTemplateMode(TemplateMode.HTML);
emailTemplateResolver.setCharacterEncoding("UTF-8");
emailTemplateResolver.setOrder(0);
emailTemplateResolver.setCheckExistence(true);
return emailTemplateResolver;
}

Answer 2

In order to define multiple template locations, you must define Spring beans implementing ITemplateResolver.
#Bean
public SpringResourceTemplateResolver firstTemplateResolver() {
SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
templateResolver.setPrefix("classpath:/templates/templatelocation/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);
templateResolver.setCharacterEncoding("UTF-8");
templateResolver.setOrder(0);
templateResolver.setCheckExistence(true);
return templateResolver;
}
#Bean
public ClassLoaderTemplateResolver secondTemplateResolver() {
ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setPrefix("templates/templatelocation/other/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);
templateResolver.setCharacterEncoding("UTF-8");
templateResolver.setOrder(1);
templateResolver.setCheckExistence(true);
return templateResolver;
}
