将elasticsearch.jar从1.7.5升级到2.3.5

Question

我已将客户端（elasticsearch.jar）从1.7.5升级到2.3.5。主要更改之一是org.elasticsearch.client.transport.TransportClient。在1.7.5版本中，org.elasticsearch.client.transport.TransportClient具有没有arg构造函数的公共构造函数。在我的applicationContext-search.xml中，我们之前已将"bean id="transportClient" class="org.elasticsearch.client.transport.TransportClient"/>替换为

<bean id="transportClient" class="org.elasticsearch.client.transport.TransportClient" factory-method="builder">
/bean>
<bean id="transportClient1" factory-bean="transportClient" factory-method="build" >
</bean>

现在，当我开始调用弹性搜索的服务时，我最终会出现以下错误

弹性搜索设置是开发环境中的一个节点。 有人可以帮助我发生什么事吗？

Answer 1

这是我的错。我做的是，在2.3.5上运行客户端（elasticsearch.jar）和在1.3.2上运行服务器 我升级服务器以匹配我的客户端，从1.3.2升级到2.3.5并且事情已经完成且工作正常。 因此，最后，确保客户端和服务器在相同版本的elasticsearch上运行.....
