我正在设置一个内置于tomcat的solr.我可以在tomcat中运行示例没问题.然后我尝试将schema.xml更改为一个非常简单的一个,我得到一个错误.
这是我的schema.xml
<?xml version="1.0" encoding="UTF-8" ?>
<schema name="minimal" version="1.1">
<types>
<fieldType name="string" class="solr.StrField"/>
</types>
<fields>
<dynamicField name="*" type="string" indexed="true" stored="true"/>
</fields>
</schema>
这是我在启动时遇到的错误:
