Please [edit] the post and share the relevant code. --- From the looks of it, no bean of type `com.saferent.saferent.mapper.ContactMessageMappe` is discovered. — Turing85, Aug 06 '23 at 21:17
Are you using mapstruct? Then you need to add a componentModel argument to the Mapper annotation. — daniu, Aug 06 '23 at 21:25
@Turing85 I have updated my codes you can check it out now. yes I am using mapStruct, you can check my pom.xml — ozz, Aug 07 '23 at 02:39
Does this answer your question? [Consider defining a bean of type 'package' in your configuration \[Spring-Boot\]](https://stackoverflow.com/questions/40384056/consider-defining-a-bean-of-type-package-in-your-configuration-spring-boot) — vaibhavsahu, Aug 07 '23 at 02:52
@vaibhavsahu i used and tried all nothing seems to be working — ozz, Aug 07 '23 at 03:33
Please trim your code to make it easier to find your problem. Follow these guidelines to create a [minimal reproducible example](https://stackoverflow.com/help/minimal-reproducible-example). — Community, Aug 07 '23 at 11:27
@Turing85 I have made the changes nothing. Would you like to see more of my codes? — ozz, Aug 07 '23 at 14:01
