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。

错误的代码写法：

@Autowired

 private 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);
        }
    }

运行后报错：

java.lang.IllegalArgumentException: The number of object passed must be even but was [1]
报错行为： request.doc(al);

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);
