解决：elasticsearch 更新报错：The number of object passed must be even but was [1]

前些天发现了一个巨牛的人工智能学习网站，通俗易懂，风趣幽默，忍不住分享一下给大家。点击跳转到教程。

1. 错误的代码写法：

 @Autowiredprivate ElasticsearchOperations esOperations; public void updateAxxxData(List<AxxxModel> axxxs) {for (AxxxModel al : axxxs) {UpdateQuery update = new UpdateQuery();update.setIndexName("coll_axxxm_sxxxxxxx_es");update.setType("coll_axxxm_sxxxxxxx_es");UpdateRequest request = new UpdateRequest();      request.doc(al);update.setUpdateRequest(request);esOperations.update(update);}}

2. 运行后报错：

  java.lang.IllegalArgumentException: The number of object passed must be even but was [1]

3. 报错行为： request.doc(al);

4. 把对象改为用Map，循环中代码调整为：

            UpdateQuery update = new UpdateQuery();update.setIndexName("coll_axxxm_sxxxxxxx_es");update.setType("coll_axxxm_sxxxxxxx_es");UpdateRequest request = new UpdateRequest();Map<String, Object> alMap = Maps.newHashMap();alMap.put("xxx_time", al.getXxx_time());alMap.put("xxx_id", al.getXxx_id());alMap.put("fxxx_id", al.getFxxx_id());request.doc(alMap);update.setUpdateRequest(request);esOperations.update(update);

5. 以上报错即消失。
