resttemplate

问题 I want to make a HTTP GET request to a not local elasticSearch and use this filter: { "query": { "bool": { "filter": [ { "range": { "timestamp": { "gte": "2019-08- 09T06:00:00","lt":"2019-08-09T08:00:00"}}} ] } } } but I don't know how to put this filter in the restTemplate.getForEntity request.

With JavaScript and other tools it is posible to make this API call with DELETE. I know java <1.8 doesent support DELETE with body, but with 1.8 it should be able: see here.
