REST API, Gfsh and PDX Serialization

[Real Wes Williams <Th...@outlook.com>]

Is there any combination of settings where I can insert JSON objects into GFSH and have them read via the REST API? All works well when I both put and get via Swagger but I can’t put via Gfsh and get via Swagger due to Pdx serialization.  Is there a way to put JSON via GFSH such that it can be read via the REST API?  Or does it require a load program?

THIS DOES NOT WORK - Put JSON object via GFSH and Get via Swagger UI

gfsh> put —region=Orders --key=“AAPL" --value=(“symbol”:"AAPL”,"shares”:"1000") --value-class=io.pivotal.domain.Order

This puts the Order into the Orders region as an Order and not as a PdxInstanceImpl

And then in the Swagger UI
GET http://192.168.0.3:7070/gemfire-api/v1/Orders/AAPL

{
  "cause": "Could not write JSON: Requested data could not convert into REST format[JSON] ; nested exception is com.fasterxml.jackson.databind.JsonMappingException: Requested data could not convert into REST format[JSON] “
}



THIS WORKS - Put JSON object via Swagger and Get via Swagger

POST http://192.168.0.3:7070/gemfire-api/v1/Orders?key=AAPL

Value:  {“symbol”:"AAPL”,"shares”:"1000"}

This puts the Order into the Orders region as a PdxInstanceImpl and not as an Order


GET http://192.168.0.3:7070/gemfire-api/v1/Orders/AAPL

Response:
{
  “symbol": “AAPL",
  “shares": “1000
}

Hi Wes,
 I think the REST interface can only deal with PDX serialized objects,
which is why you are seeing the behavior you are. There isn't a mechanism
to introspect the Order object to pull out fields & values. PDX makes this
easy since the serialized object is already stored that way.
