Client 透過 SolrServer.commit() 將資料送到Solr Server 時,
若拋出 500 Server Error 的 RumtimeException,
但資料卻有正常存入 Solrm,
可能就是 web.xml 的 Filter 先後順序的問題,
Solr 希望 SolrDispatchFilter 可以優先被處裡,
故將以下 filter 放到最前面即可

### 以下為 Server Error 時, Server 端的錯誤訊息

> 10047764 [qtp2912633-15] ERROR

> Unfortunately, the stream was empty / not available.
> This may be caused by another servlet filter calling ServletRequest.getParameter*() before SolrDispatchFilter, please remove it.
