本地使用Netty+Elasticsearch測試表單請求查詢數據，無異常。將工程打包上傳至服務器運行，頁面請求後發生異常，連接關閉。
事件：前臺通過Netty請求資源，Netty後臺通過前臺請求的JSON向ES查詢數據，發生異常。
異常狀況：

原因：本地Maven配置中引入Elasticsearch 2.1.0依賴以及Netty依賴，工程運行時，Elasticsearch底層會調用netty相關接口，而服務器中的Elasticsearch(2.1.0)在後臺運行，其也會啓動加載netty相關服務。兩者同時存在，導致數據傳輸時出現問題。
解決辦法：工程通過Maven打jar包時，排除Elasticsearch的相關jar包，只將其他依賴jar包打入。在服務器上運行時，通過設置class_path以及cp命令將服務器的ES相關jar包依賴導入，重新運行，即可。
