Scanning items from the DynamoDB table using the object persistence model in Java

Now, we are going to see how to scan items from the table using the object persistence model.

Getting ready

To perform this recipe, you should have set up the project, as described in the earlier recipes, specifically, pom.xml, dependencies, and the object model.

How to do it…

Let's scan items from the table using the object persistence model:

1. Create an instance of the DynamoDB client class and initiate it with the credential's profile. You can also set the region if you have created the table in a specific region:

   AmazonDynamoDBClient client = new AmazonDynamoDBClient(
       new ProfileCredentialsProvider());
     client.setRegion(Region.getRegion(Regions.US_EAST_1));

2. Create an instance of the DynamoDBMapper class and initiate it with the client that we created earlier:

   DynamoDBMapper mapper = new DynamoDBMapper(client);

3. Scanning allows us to put filter conditions. Here, suppose that we want to get all the items whose type...
