TIP
注意要重启 es，注意模板中的内容是你对应的。一定要确认不要搞错
@Test public void pageQueryTest() { HashMap<String, Object> scriptParams = new HashMap<>(); scriptParams.put("from", 0); scriptParams.put("size", 1); scriptParams.put("brand", "宝马"); SearchTemplateResponse searchTemplateResponse = new SearchTemplateRequestBuilder(client) .setScriptType(ScriptType.FILE) .setScript("page-query-by-brand") // page-query-by-brand.mustache .setScriptParams(scriptParams) .setRequest(new SearchRequest("car_shop").types("sales")) .get(); SearchResponse response = searchTemplateResponse.getResponse(); System.out.println(searchTemplateResponse.getResponse()); SearchHit[] hits = response.getHits().getHits(); for (SearchHit hit : hits) { System.out.println(hit.getSourceAsString()); } client.close(); }Copied!
