Execute java code with spring dependencies before JMeter test

I'm trying to do some stress tests on an API with JMeter. I have two environments (QA and production) and I want to set up QA's database before running JMeter tests.

I can't use JDBC or MongoDB configuration elements because it's a cloud database (DynamoDB - AmazonWS). I thought about using raw requests with API-token to AmazonWS's API but I'd prefer to use a Java class I already have (a class that create-delete queries to cloud DB) but it has Spring dependencies.

I know that with JMeter I can run some Java code but I don't know how to run classes with Spring dependencies like a BeanFactoryPostProcessor.

Any ideas?
