Configure DynamoDB Connection For Spring Boot Now we have spring boot project with all the dependencies to access DynamoDB database and locally configured DynamoDB instance. Repository Layer – We define data reads and writes using a repository layer.īasic architecture for Spring Boot app with MongoDB Developing the API.Service Layer – We define the business logic with processing data in this layer.We should only use the controller layer to capture the consumer’s request and pass it to the service layer, then return the service’s response to the consumer. Controller Layer – This is the place API consumers communicating with, and we define REST path Request Body Responses here.In this tutorial I’m going to use 3 main layers with the architecture, Those are controller, service and repository layers. Our main API endpoints for this tutorial will be, Endpoint Spring Boot REST API Using Spring Data MongoDB Tutorial.Spring Boot REST API Using JPA, Hibernate, MySQL Tutorial.This same API has developed using the MySQL and MongoDB databases as well. additionally, the author could have multiple books and members should be registered to lend any book from the library. In this scenario, there are authors registered in the system. Here I’ll develop REST API with basic CRUD operations to cover functions inside a book library. If you are using Maven based project add above libraries as follows, implementation 'com.amazonaws:aws-java-sdk-dynamodb:1.11.892'Ĭompile group: '', name: 'spring-data-dynamodb', version: '5.1.0'Īdditionally there is one more additional dependency we should add through dependencyManagement as below. If you are using Gradle based spring boot application, add the following dependencies to the project. Ok now we have our base spring boot project, Now we need to add libraries which allows us to access DynamoDB database. If you need to learn how we can use Lombok in spring boot follow our article Guide to use Lombok In Spring Boot. Never write another getter or equals method again, with one annotation your class has a fully-featured builder, Automate your logging variables, and much more. Lombok – The coolest plugin to spicing up your java.Spring Web – contains common web-specific utilities for both Servlet and Portlet environments.Here I’ve selected following dependencies to create spring boot project using spring initilizr,
generating spring boot application with spring initializr

If you are really new to Spring Boot, Please follow our article on How to Create a Spring Boot Project. NoSQL workbench for dynamoDBįor this tutorial I’ll use spring initializr to generate a spring boot project with all the dependencies I need for this tutorial. Then use ‘ NoSQL Workbench for DynamoDB‘ client to access the database. By using the -sharedDb flag when starting the local DynamoDB, a single database file will be shared for all clients.
Keep in mind to add -sharedDB while running DynamoDB with docker otherwise it will create separate databases for separate clients. Using SimpleLogger to log to the console. Sample output after dynamoDB has started correctly, Initializing DynamoDB Local with the following configuration:ĮRROR StatusLogger Log4j2 could not find a logging implementation. docker run -p 8000:8000 amazon/dynamodb-local -jar DynamoDBLocal.jar -inMemory -sharedDb If you are not familiar with Docker deployments please follow this instruction on Deploying DynamoDB Locally on Your Computer. Here I explain the way we could run the DynamoDB local instance using docker.
