Spring-Boot with JSP Tag Libs in embedded Tomcat

Question

I am currently migrating a Spring MVC Webapp (xml-config to java-config, tomcat to embedded tomcat via spring-boot).

The webapp uses freemarker as templating engine

Answer 1

Spring Boot doesn't support the use of JSP taglibs with Freemarker out of the box. There's an open enhancement request that you might be interested in. It contains a link to a possible workaround where you configure FreemarkerConfigurer's tag lib factory with some additional TLDs to be loaded from the classpath:

freeMarkerConfigurer.getTaglibFactory().setClasspathTlds(…);
