There is no detailed tutorial for version 3, but the principle remains the same as in version 2. Just use the templates updated for version 3 : https://github.com/telosys-templates-v3/java7-persistence-spring-data-jpa etc. You can also reuse V2 templates : https://github.com/telosys-tools/spring-data-rest-templates-TT210 (they haven't been qualified with V3 yet but if they needed adaptation it should be minor)
Thank you for the quick response. Can you please clarify these questions. Is there a plug in to generate controller/Resources in v3 version ? Also is there a way to enable database model in V3 .
