Question

我需要将MongoDB的数据同步到Solr。

当我发出命令

时

mongo-connector -m dbserver:27018 -n shop -t http://localhost:8983/solr/Search --auto-commit-interval=0 -d solr_doc_manager

错误日志是：

我不知道我错在哪里。请帮我解决这个问题。谢谢。

来自-n参数的the documentation：

从MongoDB读取的集合列表。集合名称应以database_name.collection_name
的形式给出

所以你错过了参数的database_name或collection_name，这取决于MongoDB的结构。

mongo-connector没有将数据从MongoDB同步到Solr
