ElasticSearch-The number of object passed must be even but was [1]-问题解决

ES版本：6.4.3

1、The number of object passed must be even but was [1]

问题代码：

IndexRequest indexRequest = new IndexRequest(INDEX,TYPE,water.getId()).source(jsonStr);

解决：将jsonStr换成Map。

不报该错误了，但是又报错：

2、cannot write xcontent for unknown value of type class java.math.BigDecimal

解决：将6.4.3升级到6.7.2。

<es.version>6.7.2</es.version>
