Olá,

Aparentemente, o autowire do amazonS3 não está funcionando, como ficou a sua classe AmazonConfiguration?

Ficou assim:

package br.com.casadocodigo.loja.configuration;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.amazonaws.auth.AWSStaticCredentialsProvider;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.s3.AmazonS3;
import com.amazonaws.services.s3.AmazonS3ClientBuilder;

@Configuration
public class AmazonConfiguration {

    private static final String ACCESS_KEY="xxx";
    private static final String SECRET_KEY="xxx";
    private static final String REGION="us-east-1";

    @Bean
    public BasicAWSCredentials BasicAWSCredentials() {
        return new BasicAWSCredentials(ACCESS_KEY, SECRET_KEY);
    }

    public AmazonS3 amazonS3() {
        return AmazonS3ClientBuilder.standard().withRegion(REGION)
            .withCredentials(new AWSStaticCredentialsProvider(BasicAWSCredentials())).build();
    }


}

Rafael, desculpe, assim que colei o código aqui vi que estava faltando o @Bean no AmazonS3.

Fiz o restart do tomcat e subiu.

Obrigado pela ajuda e desculpe.
