我正在尝试将 PostgreSQL 数据库导入 Solr 4.3.1，到目前为止，我将此代码添加到 Solrconfig.xml ：
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">db-data-config.xml</str>
</lst>
</requestHandler>
这就是新创建的 db-data-config.xml
<dataConfig>
<dataSource driver="org.postgresql.Driver"
url="jdbc:postgresql://localhost:5432/test"
user="postgres"
password="123" />
<document>
<entity name="phonebook" query="SELECT phone, firstname from phonebook">
<field column="phone" name="id" />
<field column="firstname" name="name" />
<entity name="revision" query="select rev_id from revision where rev_page=${phonebook.phone}">
<entity name="pagecontent" query="select old_text from pagecontent where old_id=${revision.rev_id}">
<field column="old_text" name="text" />
</entity>
</entity>
</entity>
</document>
</dataConfig>
所有这些文件都在 collection1 目录下，我做错了什么吗？
编辑：
当我使用 localhost:435/solr/TEST/dataimport 连接时
我收到这个错误
