SpringBoot REST Controller throws "can not have an entity parameter error"

I have the following Spring Boot Controller:
import java.io.InputStream;
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.att.aft.dme2.internal.javaxwsrs.PUT;
import com.att.bttw.model.HelloWorld;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiResponse;
import io.swagger.annotations.ApiResponses;
#Api
#Path("/service")
#Produces({ MediaType.APPLICATION_JSON })
public interface RestService {
#PUT
#Path("/datarouter/{filename}")
#Consumes("application/gzip")
#Produces(MediaType.APPLICATION_JSON)
Response testEndpoint(#Context HttpServletRequest request, #PathParam("filename") String filename, InputStream inputStream);
}
The implementation of this method is simply:
import javax.servlet.http.HttpServletRequest;
import javax.ws.rs.core.Response;
import org.springframework.stereotype.Component;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.client.RestTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import com.att.bttw.model.ApplicationResults;
import com.att.bttw.model.CountsDataModel;
import com.att.bttw.model.CountsDataResults;
import com.att.bttw.model.DisplayFieldRecord;
import com.att.bttw.model.DisplayRecord;
import com.att.bttw.model.WatermarkEventObject;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.IOException;
import java.io.InputStream;
import java.sql.Timestamp;
import java.time.Instant;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.stream.Collectors;
#Override
public Response testEndpoint(HttpServletRequest request, String filename, InputStream inputStream) {
System.out.println("File name consumed: " + filename);
return null;
}
When I try to hit this endpoint, I get the following error:
"Following issues have been detected: Response testEndpoint(javax.servlet.http.HttpServletRequest, java.lang.String, java.io.InputStream), can not have an entity parameter. Try to move the parameter to the corresponding resource method".
When I remove the InputStream and HttpServletRequest parameters, the endpoint works just fine, I'm just not understanding the error message I'm getting.

How to resolve the error java.lang.NoSuchMethodError: com.amazonaws.SDKGlobalConfiguration.isInRegionOptimizedModeEnabled()Z?

I am trying to upload a file to S3 and getting error like
Target exception: java.lang.NoSuchMethodError:
com.amazonaws.SDKGlobalConfiguration.isInRegionOptimizedModeEnabled()Z
Code is
String accessKey="accesskey";
String secretKey="mysecretkey"
AWSCredentials credentials = new BasicAWSCredentials(accessKey, secretKey);
AmazonS3 conn = new AmazonS3Client(credentials);
In the line of AmazonS3 conn = new AmazonS3Client(credentials); I am getting the target exception.
Totally I imported these many java packages showing below. still getting the same error.

Trying to import vk.core.api in Java

I'm trying to import vk.core.api in Java but when I try to compile it, I get only errors like "error: package vk.core.api does not exist

You need to add in the dependencies of your build.gradle something like:
compile group: 'de.hhu.stups', name: 'virtual-kata-lib', version: '1.0.0'
