我正在用solr连接MongoDB，
遵循此文档进行集成：https://blog.toadworld.com/2017/02/03/indexing-mongodb-data-in-apache-solr
DB.Collection： solr.wlslog
D：\ solr \ bin>的路径
mongo-connector --unique-key=id -n solr.wlslog -m localhost:27017 -t http://localhost:8983/solr/wlslog -d solr_doc_manager
我正在得到以下答复和错误：

我在GitHub问题中搜索了mongo-connector，但未找到任何解决方案：
终于解决了问题：）
我的系统操作系统是Windows，并且我已经在C:\Program Files\MongoDB\（系统的驱动器）中安装了mongodb，
在此mongo-connector连接之前，我已根据此blog使用以下命令启动了mongodb的副本集：
mongod --port 27017 --dbpath ../data/db --replSet rs0
问题：
--dbpath ../data/db目录中的问题，此目录位于C:\Program Files\MongoDB\Server\4.2\data\db中，此目录具有所有权限，但父目录C:\Program Files由于其系统目录和受保护的目录而没有所有权限。
解决方案：
我刚刚将我的--dbpath更改为该目录位于系统受保护目录之外的另一个路径，如下所示：
mongod --port 27017 --dbpath C:/data/db --replSet rs0
在那之后，我执行了以下连接命令，如我在问题中所张贴的：
mongo-connector --unique-key=id -n solr.wlslog -m localhost:27017 -t http://localhost:8983/solr/wlslog -d solr_doc_manager
成功的mongo连接器日志结果：
