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

Question

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);
    }
}

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!");
    }
}

Here is my build.gradle :

buildscript {
    ext {
        springBootVersion = '1.5.3.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        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()
}

dependencyManagement {
    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")
    runtime('org.springframework.boot:spring-boot-devtools')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

The stack trace after requesting GET localhost:8080/ :

I suspect the problem is how I am using Spring, because the same controller works in a simple Java application. Thus, I have verified my credentials are not the issue.

Answer 1

This worked for me, I was using version 1.10.12 of the SDK Before I changed my dependency to version 1.11.136 of the aws-java-sdk and that resolved my issue

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk</artifactId>
  <!--  <version>1.10.12</version> -->
    <version>1.11.136</version>
</dependency>

Answer 2

Was stuck on this issue for hours.

Just update the aws-java-sdk version you are using from 1.10 to 1.11.x. It would start working. :)

Answer 3

Hm... Generally speaking it is not a good idea to have business logic in controller - it should be in service, and service method should be called from controller. Anyhow, try something like this: 1) Create AWS Config class:

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.regions.Region;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.s3.AmazonS3Client;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class AWSConfiguration {

@Bean
public AWSCredentials awsCredentials() {
    return new ProfileCredentialsProvider().getCredentials();
}

@Bean
public AmazonS3Client amazonS3Client(AWSCredentials awsCredentials) {
    AmazonS3Client amazonS3Client = new AmazonS3Client(awsCredentials);
    amazonS3Client.setRegion(Region.getRegion(Regions.US_EAST_1));
    return amazonS3Client;
}

}

2)Now you can create AmazonS3Client objects (autowired) in your other classes, and use the client to make requests to S3.
