jmeter-我需要額外的連接mysql數據庫嗎？

以我JMeter測試計劃，我創建了一個線程組和添加有JDBC連接配置config元素：jmeter-我需要額外的連接mysql數據庫嗎？

Url: jdbc:mysql://localhost:3306/atmdb, 
Driver class: com.mysql.jdbc.Driver 
username: **** 
password: ****

我還添加JDBC請求採樣器和視圖結果樹偵聽器。但執行這個測試計劃後，我看到這個錯誤：

有人可以幫助我嗎？

看來你沒有在JMeter的Lib文件夾中放置正確的mysql連接器文件。請下載此jar文件並將其放置在JMeter安裝的Lib文件夾中。

您可以從以下網址下載最新使用mysql-connector-java的5.1.38-bin.jar：https://dev.mysql.com/downloads/connector/j/3.1.html

要正確配置MySQL JDBC連接是指官方JMeter的文檔：http://jmeter.apache.org/usermanual/component_reference.html#JDBC_Connection_Configuration

感謝您的快速回復.....我完全按照您的說法做了，但不起作用。 –

myqsql連接器也需要與正在使用的mysql數據庫兼容。所以，你需要檢查你試圖連接的mysql的變種/版本。然後搜索與您的數據庫兼容的連接器。 – TestingWithArif

爲了獲得更可靠的結果，最好在不同的機器上安裝JMeter和MySQL服務器，因爲它們可能會干擾並爭奪機器資源。
Download MySQL JDBC Driver並將其放到JMeter的類路徑（通常是JMeter安裝的/ lib文件夾）。另外，您可以在Test Plan級別配置路徑
如果複製.jar文件到/ lib文件夾 - 重啓JMeter的挑選的.jar了
我也建議檢查出Debugging JDBC Sampler Results in JMeter指導學習如何執行關聯，添加斷言等。

按照以下兩個步驟解決問題。它解決了我的

將Apache的JMeter的-3.0 \ lib文件夾
重新啓動JMeter的

重啓後僅會挑選新放置的jar文件裏面的MySQL連接罐子。
