关于java里使用Script的问题

Map<String, Object> params = new HashMap<String, Object>(); 

params.put("message2", "22345678dddd91");



updateRequest.script(new Script(Script.DEFAULT_SCRIPT_TYPE, Script.DEFAULT_SCRIPT_LANG, "def message2 =''; ctx._source.message2 = message2;",params));

client.prepareUpdate("ttl", "doc", "1") .setScript(new Script("ctx._source.gender = \"male\"" , ScriptService.ScriptType.INLINE, null, null)) .get();
