带有SQL Server的JMeter JDBC请求

问题描述 投票：0回答：1

我无法使JMeter JDBC请求与SQL Server一起使用。

我在this article之后准备了一个最简单的示例：

问题是，

  • JDBC PreProcessor中的SQL有效，但在Debug Sampler输出中没有看到它创建的JMeter变量。
  • 但是JDBC Request中的SQL不起作用。它给出了
    • 的错误

Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver'

这很奇怪，因为JDBC PreProcessor中的JDBC驱动程序和SQL很好用。

  1. 您的PreProcessor根本无法工作，因为它不能在没有Sampler的情况下运行，因此它只是ignored，您可以在setUp线程组中添加Dummy Sampler，这将触发JDBC PreProcessor的执行] >
  2. Cannot load JDBC driver class 'com.microsoft.sqlserver.jdbc.SQLServerDriver'错误意味着您在JDBC Driver中没有MSSQL JMeter Classpath

    3. 所以您需要：

  1. 下载Microsoft JDBC Driver for SQL Server，然后将mssql-jdbc-x.x.x.jrex.jar文件解压缩到JMeter安装的“ lib”文件夹中。需要重新启动JMeter才能拾取.jar
  2. 在JDBC连接配置中使用select 1作为验证查询
