错误：org.apache.solr.common.SolrException: Could not load config for solrconfig.xml
解决：solr/home位置不对。让它指向solr-4.1.0\example\solr就行了，我已经copy到WebRoot了。
找到web.xml中的
<!--
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>/put/your/solr/home/here</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
-->
修改成
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>C:/CHRUAN/workspace/solr-4.1.0/WebRoot/solr</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
