# 📚 Spring Data DynamoDB Examples - 📘 REST integration

This example shows how to use `spring-data-dynamodb` with `spring-data-rest` to automatically expose CRUD operations on DynamoDB entities via REST endpoints.

Further explanation can be found 
* as also the [code](src/main/java/com/github/derjust/spring_data_dynamodb_examples/rest)

### 📜 Code sample


```java

@EnableDynamoDBRepositories(
		mappingContextRef = "dynamoDBMappingContext",
		includeFilters = {@ComponentScan.Filter(type = FilterType.ASSIGNABLE_TYPE, classes = {
				UserRepository.class}
		)}
)


@Bean
public DynamoDBMappingContext dynamoDBMappingContext() {
    return new DynamoDBMappingContext();
}

```


### 📝 How to prepare:
* Update `src/main/resources/application.properties`

| Key                          | Sample value                           | Description                                       |
|------------------------------|----------------------------------------|---------------------------------------------------|
| `amazon.aws.accesskey`       | N/A                                    | AWS accesskey for DynamoDB                        |
| `amazon.aws.secretkey`       | N/A                                    | AWS secretkey for DynamoDB                        |

### ▶️ How to run: 
```
mvn compile exec:java@rest
```
