解决办法：
在于修改solr的配置文件，使其能准确的找到core的位置，本熊推测core的作用正是像处数据理机一样，里面集成了分词器等，使其可以可以建立索引。
- 在TomcatPath下
/webapps/solr/WEB-INF的文件内修改web.xml文件，将选取部分的注释取消（将开头<!--的和结尾的-->消除即可）
修改web.xml
正确的写法是
<env-entry> <env-entry-name>solr/home</env-entry-name> <env-entry-value>/home/as/workspace/tomcat/solr</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry>
