Hallo,
I'm trying to convert a working REST Update Request to a similar JAVA call.
{
"script" :
"ctx.\_source.service.serviceUnits[index].allotments.remove(oldAllotment);
ctx.\_source.service.serviceUnits[index].allotments += newAllotment",
"params" : {
"index": 0,
"oldAllotment" :
{"reference":"---","date":"2013-01-01","amount":12,"requestAllowed":false,"salesChannel":"-","releaseDate":"2013-12-31"},
"newAllotment" :
{"reference":"---","date":"2013-01-01","amount":0,"requestAllowed":true,"salesChannel":"-","releaseDate":"2013-12-31"}
}
}
private static final String MERGEALLOTMENT =
"ctx.\_source.service.serviceUnits[index].allotments.remove(oldAllotment);ctx.\_source.service.serviceUnits[index].allotments
+= newAllotment";
Map\ params = new HashMap\();
params.put("index", index);
params.put("oldAllotment", oldAllotment);
params.put("newAllotment", newAllotment);
UpdateResponse actionGet = client.prepareUpdate("catalyst", hit.getType(),
hit.getId())
.setScript(MERGEALLOTMENT)
.setScriptParams(params)
.execute()
.actionGet();
I have allready tried several combinations like:
Map\ params = new HashMap\();
params.put("index", index);
params.put("oldAllotment", mapper.writeValueAsString(oldAllotment));
params.put("newAllotment", mapper.writeValueAsString(newAllotment));
but haven't found any working solution.
can anybody help me on how to set the params map right.
-Alex

got it working
Map\ params = new HashMap\();
params.put("index", index);
params.put("oldAllotment", mapper.convertValue(oldAllotment, Map.class));
params.put("newAllotment", mapper.convertValue(newAllotment, Map.class));
