Multiple things can cause this  I didn t bother to check your entire repository  so I m going out on a limb here   First off  you could be missing an annotation   Service or  Component  from the implementation of com example my services user UserService  if you re using annotations for configuration  If you re using  only  xml  you re probably missing the  lt bean gt  -definition for the UserService-implementation   If you re using annotations and the implementation is annotated correctly  check that the package where the implementation is located in is scanned  check your  lt context component-scan base-package  -value

In my case it was the wrong dependecy for CrudRepository  My IDE added also follwing        lt dependency gt           lt groupId gt org springframework data lt  groupId gt           lt artifactId gt spring-data-commons lt  artifactId gt           lt version gt 1 11 2 RELEASE lt  version gt       lt  dependency gt    But I just needed        lt dependency gt           lt groupId gt org springframework boot lt  groupId gt           lt artifactId gt spring-boot-starter-data-jpa lt  artifactId gt           lt version gt RELEASE lt  version gt       lt  dependency gt    I removed the first one and everything was fine

IF this is only occurring on deployments  be sure that you have the dependency of the package you are referencing in the  war   For instance  this was working locally on my machine  with debug configurations working fine  but after deploying to Amazon s Elastic Beanstalk   I received this error and noticed one of the dependencies was not bundled in the  war package

[java] No matching bean of type ... found for dependency
