Barrett Oglesby commented on GEODE-9104:
----------------------------------------
The query executes this code path:
{noformat}
java.lang.Exception
at
org.apache.geode.rest.internal.web.util.JSONUtils.enableDisableJSONGeneratorFeature(JSONUtils.java:57)
at
org.apache.geode.rest.internal.web.util.JSONUtils.convertCollectionToJson(JSONUtils.java:141)

org.apache.geode.rest.internal.web.controllers.AbstractBaseController.processQueryResponse(AbstractBaseController.java:243)
at
org.apache.geode.rest.internal.web.controllers.QueryAccessController.runNamedQuery(QueryAccessController.java:262)
{noformat}
JSONUtils creates a JsonGenerator like:
{noformat}
getObjectMapper().getFactory().createGenerator((OutputStream) outputStream,
JsonEncoding.UTF8)
{noformat}
It then enables the ESCAPE_NON_ASCII feature:
{noformat}
generator.enable(JsonWriteFeature.ESCAPE_NON_ASCII.mappedFeature());
{noformat}
This is what causes the Chinese characters to be escaped.
The get creates a RegionData in this code path:
{noformat}
java.lang.Exception: RegionData.RegionData
at
org.apache.geode.rest.internal.web.controllers.support.RegionData.<init>(RegionData.java:59)
at
org.apache.geode.rest.internal.web.controllers.support.RegionEntryData.<init>(RegionEntryData.java:48)
at
org.apache.geode.rest.internal.web.controllers.PdxBasedCrudController.getRegionKeys(PdxBasedCrudController.java:260)
at
org.apache.geode.rest.internal.web.controllers.PdxBasedCrudController.read(PdxBasedCrudController.java:243)
{noformat}
The RegionData is serialized here:
{noformat}
java.lang.Exception: RegionData.serialize
at
org.apache.geode.rest.internal.web.controllers.support.RegionData.serialize(RegionData.java:131)

at
org.springframework.http.converter.AbstractGenericHttpMessageConverter.write(AbstractGenericHttpMessageConverter.java:104)
{noformat}
AbstractJackson2HttpMessageConverter.writeInternal creates a JsonGenerator like
this:
{noformat}
objectMapper.getFactory().createGenerator(outputStream, encoding)
{noformat}
This is the same as JSONUtils. The ESCAPE_NON_ASCII is not enabled in this
case, though.

> Key: GEODE-9104
> URL: https://issues.apache.org/jira/browse/GEODE-9104
> Project: Geode
> Issue Type: Bug
> Components: rest (dev)
> Reporter: Barrett Oglesby
> Assignee: Barrett Oglesby
> Priority: Major
>
> For example, if JSON containing Chinese characters is put:
> {noformat}
> curl -X PUT -H "Content-Type: application/json"
> localhost:8081/geode/v1/customers/1 -d '{"id": "1", "firstName": "名",
> "lastName": "姓"}'
> {noformat}
> The results of getting the entry are correct:
> {noformat}
> curl localhost:8081/geode/v1/customers/1
> {
> "id" : "1",
> "firstName" : "名",
> "lastName" : "姓"
> }
> {noformat}
> The results of querying the entry show the field values escaped:
> {noformat}
> curl -G http://localhost:8081/gemfire-api/v1/queries/adhoc --data-urlencode
> "q=SELECT * FROM /customers where id='1'"
> [ {
> "id" : "1",
> "firstName" : "\u540D",
> "lastName" : "\u59D3"
> } ]
> {noformat}
