Google end point returns JSON for long data type in quotes - json

Question

I am using Google cloud end point for my rest service. I am consuming this data in a GWT web client using RestyGWT.
I noticed that cloud end point is automatically enclosing a long datatype in double quotes which is causing an exception in RestyGWT when I try to convert JSON to POJO.
Here is my sample code.
#Api(name = "test")
public class EndpointAPI {
#ApiMethod(httpMethod = HttpMethod.GET, path = "test")
public Container test() {
Container container = new Container();
container.testLong = (long)3234345;
container.testDate = new Date();
container.testString = "sathya";
container.testDouble = 123.98;
container.testInt = 123;
return container;
}
public class Container {
public long testLong;
public Date testDate;
public String testString;
public double testDouble;
public int testInt;
}
}
This is what is returned as JSON by cloud end point. You can see that testLong is serialized as "3234345" rather than 3234345.
I have the following questions.
(1) How can I remove double quotes in long values ?
(2) How can I change the string format to "yyyy-MMM-dd hh:mm:ss" ?

Answer 1

What version of restyGWT are you using ? Did you try 1.4 snapshot ?
I think this is the code (1.4) responsible for parsing a long in restygwt, it might help you :
public static final AbstractJsonEncoderDecoder<Long> LONG = new AbstractJsonEncoderDecoder<Long>() {
public Long decode(JSONValue value) throws DecodingException {
if (value == null || value.isNull() != null) {
return null;
}
return (long) toDouble(value);
}
public JSONValue encode(Long value) throws EncodingException {
return (value == null) ? getNullType() : new JSONNumber(value);
}
};
static public double toDouble(JSONValue value) {
JSONNumber number = value.isNumber();
if (number == null) {
JSONString val = value.isString();
if (val != null){
try {
return Double.parseDouble(val.stringValue());
}
catch(NumberFormatException e){
// just through exception below
}
}
throw new DecodingException("Expected a json number, but was given: " + value);
}
return number.doubleValue();
}
