How to use Spring Data DynamoDB example | Spring Boot

In tradition approach, implementing Data Access Layer makes lots of boilerplate code. Spring Data helps us improve our codes and reduce efforts for development and maintenance. It supports us the ways to write interface for repositories and custom finder methods, the implementation will be done automatically by Spring Framework. In this tutorial, we're gonna look at how to use Spring Data DynamoDB with Spring Boot.

  • Class Customer corresponds to entity and table Customer.

  • CustomerRepository is an interface extends CrudRepository, will be autowired in WebController for implementing repository methods and custom finder methods.

  • WebController is a REST Controller which has request mapping methods for RESTful requests such as: save, delete, findall, findbyid, findbylastname.

  • Configuration for DynamoDB properties in application.properties. The accesskey and secretkey are just arbitrary values and are not needed to actually authenticate when accessing local instance of DynamoDB. The properties will be dynamically pulled out in the DynamoDBConfig.

  • Dependencies for Spring Boot and DynamoDB in pom.xml

    III. Practice

    1. Create Spring Boot project & add Dependencies
