[FIXED] Spring unable to resolve bean

Issue

Spring 4 and Tomcat.

Im trying to migrate a very simple spring-bootstrap project to a traditional spring webApp without spring boot. The problem is i cant get dependency injection work because aparently im not telling spring where/how to look up for beans.

You can find my source code at:

https://github.com/aleponchu/SpringTomcatJsp

When i deploy the project in tomcat i get this stack trace :

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [monkey.woodstock.repositories.ProductRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredMethodElement.inject(AutowiredAnnotationBeanPostProcessor.java:553)

And here is the complete stack trace :

Thanks to everyone in advance.

Solution

1. Remove @Repository Annotation on ParteRepository and ProductRepository.

2. Add <jpa:repositories base-package="monkey.woodstock.repositories" /> in your mvc-dispatcher-servlet.xml so that the ParteRepository and ProductRepository will be registered as a JpaRepository beans.

3. You need configure the EntityManagerFactoryBean, TransationManager, JPA properties and also the JPAVendor(ex- Hibernate). See this tutorial on how to configure them using Java configuration and XML configuration.

See this standalone example.
