Testing

Make sure that a table has been created in dynamoDB:

 aws --endpoint-url=http://localhost:4566 dynamodb describe-table --table-name hotels

Create Hotel entities:

http -v :9080/hotels id=1 name=test1 address=address1 zip=zip1 state=OR
http -v :9080/hotels id=2 name=test2 address=address2 zip=zip2 state=OR
http -v :9080/hotels id=3 name=test3 address=address3 zip=zip3 state=WA

Get Hotels by State names:

http ":9080/hotels?state=OR"
http ":9080/hotels?state=WA"

Get Hotels by ID:

http ":9080/hotels/1"
http ":9080/hotels/2"
http ":9080/hotels/3"

Update Hotel:

http PUT :9080/hotels/1 name=test1updated address=address1 zip=zip1 state=OR version=1

Version Demo:

http :9080/hotels id=4 name=name address=address zip=zip state=OR
http PUT :9080/hotels/4 name=name1 address=address zip=zip state=OR version=1
http PUT :9080/hotels/4 name=name1 address=address1 zip=zip state=OR version=2
