错误分析:可能的原因是你更改了solr的索引库名(即collection1),并且你的solr配置文件类似如下所示:
<!-- solr服务器地址 此配置中默认索引库名为collection1-->
<solr:solr-server id="solrServer" url="http://127.0.0.1:8080/solr" />
纠正措施1:在core.properties文件中改回你的core名为collection1;
也可采用措施2:指定索引库名比如core1
<!-- solr服务器地址-->
<solr:solr-server id="solrServer" url="http://127.0.0.1:8080/solr/core1" />
