Spring Boot does not recognize application.properties file

I am trying to configure a DynamoDb client using Spring Boot and put my endpoints and configuration information in a resources / application.properties file. However, Spring Boot does not seem to take these properties. It takes the key "server.default", which I saved in the same file, so it definitely recognizes the file itself.

Here is my application.properties file and the class I'm trying to load into ( DynamoDBClientMapper ):

amazon.dynamodb.endpoint=http://localhost:8000/
amazon.dynamodb.region=us-west-1
amazon.aws.accesskey=key
amazon.aws.secretkey=key2

server.port=8080

Here is my project structure: enter image description here

, . @PropertySource , EnableAutoConfiguration, .

@PropertySource("database.properties")
public class DynamoClientMapper {

    @Value("${amazon.dynamodb.endpoint}")
    private String amazonDynamoDBEndpoint;

    @Value("${amazon.aws.accesskey}")
    private String amazonAWSAccessKey;

    @Value("${amazon.aws.secretkey}")
    private String amazonAWSSecretKey;

    @Value("${amazon.aws.region}")
    private String amazonAWSRegion;

App.java:

@SpringBootApplication
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
public class App {

//    private static final Logger logger = Logger.getLogger(App.class.toString());

    public static void main(String[] args){
        SpringApplication.run(App.class, args);
    }
}

:
