Autowiring DynamoDB Repository in Spring Boot application using Spring Data

Tags:

spring-boot

I'm making my first steps with Spring Boot and now for a while, I am stuck with the following issue.

Goal

I want to store application data in DynamoDB on AWS using Spring Data. For this purpose, there should be a single service that encapsulates everything related to persistence. The code should be as simple and readable as possible. Therefore, I try to avoid XML configurations and use annotations instead.

Problem

Spring fails to autowire an instance of the repository in the DataService (NoSuchBeanDefinitionException).

UPDATE: The integration test also has a dependency on the repository using @Autowire (see below) and fails as well. I also tried to create a dummy implementation of the repository interface and mark it as @Component - which also works fine.

Therefore, I assume that Spring cannot find the DynamoDB implementation of the repository in my setup. The reason for this, however, I do not understand. All documentation tells me that I simply need to define a repository interface and let Spring Data do the magic.

Here is the stacktrace:

java.lang.IllegalStateException: Failed to load ApplicationContext

Any help on this is highly appreciated. Thanks in advance!

The problem is in @EnableDynamoDBRepositories in DynamoDBConfig. The base package should be "de.ci.eco1.demo.taskboard.persistence" which is the package of your repository class. You mistyped it as "de.ci.eco1.demo.persistence".

The class which is autowiring AmazonDynamoDB keep annotate the class with @Repository and make the bean in main class. Below code snippet is working for me. 

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
    @Repository
    public class DaoImpl implements MemberDao {

        @Autowired
        private AmazonDynamoDB amazonDynamoDB;

    ...
    ...
    }

@Bean(name= "dynamoDB")
    public AmazonDynamoDB getAmazonDynamoDB(){
        AmazonDynamoDB  dynamoDB =  AmazonDynamoDBClientBuilder.standard()
                .withRegion(Constants.REGION)
