at java.lang.Thread.run(Thread.java:748)解决办法就是把Spring配置Solr的ip改成公网ip。
<bean id="httpSolrClientBuilderArticle" class="org.apache.solr.client.solrj.impl.HttpSolrClient.Builder">
<constructor-arg name="baseSolrUrl" value="http://localhost:8081/blog-solr/article_core" />
</bean>
改成
<bean id="httpSolrClientBuilderArticle" class="org.apache.solr.client.solrj.impl.HttpSolrClient.Builder">
<constructor-arg name="baseSolrUrl" value="http://公网ip:端口/blog-solr/article_core" />
</bean>
创建索引时如果出现了ERROR adding document SolrInputDocument添加到文档库失败，也可以试试这种方式，本地和线上环境确实不一样。
