Cannot use AWS SDK in Spring Boot Application (Socket not created by this factory)

Question 1

I am trying to create a basic Spring Boot application that interacts with AWS S3. I am only trying to get the list of buckets:

I start out with a basic Application:

@SpringBootApplication
public class Application {

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

@SpringBootApplication

public class Application {

public static void main(String[] args) {

SpringApplication.run(Application.class, args);

}

My problem occurs in the Controller:

@RestController
public class S3RestController {

    @RequestMapping(path = "/", method = RequestMethod.GET)
    public ResponseEntity<String> index() {

        AWSCredentials credentials;
        try {
            credentials = new ProfileCredentialsProvider().getCredentials();
        } catch (Exception e) {
            throw new AmazonClientException("Cannot load credentials.");
        }

        AmazonS3 s3 = new AmazonS3Client(credentials);
        s3.setRegion(Region.getRegion(Regions.US_EAST_1));

        s3.listBuckets();

        return ResponseEntity.ok("Hello!");
    }
}

@RestController

public class S3RestController {

@RequestMapping(path = "/", method = RequestMethod.GET)

public ResponseEntity index() {

AWSCredentials credentials;

try {

credentials = new ProfileCredentialsProvider().getCredentials();

} catch (Exception e) {

throw new AmazonClientException("Cannot load credentials.");

}

AmazonS3 s3 = new AmazonS3Client(credentials);

s3.setRegion(Region.getRegion(Regions.US_EAST_1));

s3.listBuckets();

return ResponseEntity.ok("Hello!");

}

Here is my build.gradle:

buildscript {
    ext {
        springBootVersion = '1.5.3.RELEASE'
    }
    repositories {
        mavenCentral()

        classpath "io.spring.gradle:dependency-management-plugin:1.0.0.RC2"
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: "io.spring.dependency-management"

version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

    imports {
        mavenBom 'com.amazonaws:aws-java-sdk-bom:1.10.77'
    }
}

dependencies {
    compile('com.amazonaws:aws-java-sdk-s3')
    compile("org.springframework.boot:spring-boot-starter-web")
