从这个documentation中学习,我尝试使用Gatling JDBC feeder从带有Windows身份验证的SQL Server中获取数据。
我在POM.xml中添加了这个依赖项
<!-- https://mvnrepository.com/artifact/dev.code-n-roll.gatling/jdbc-gatling -->
<dependency>
<groupId>dev.code-n-roll.gatling</groupId>
<artifactId>jdbc-gatling_2.12</artifactId>
<version>2.3.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/io.gatling/gatling-jdbc -->
<dependency>
<groupId>io.gatling</groupId>
<artifactId>gatling-jdbc</artifactId>
<version>3.4.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.microsoft.sqlserver/mssql-jdbc -->
<dependency>
<groupId>com.microsoft.sqlserver</groupId>
<artifactId>mssql-jdbc</artifactId>
<version>7.4.1.jre8</version>
</dependency>
我的连接字符串如下所示
import io.gatling.jdbc.Predef._
val databaseUrl = "jdbc:sqlserver://CentralSQLServer:1433;databaseName=CustomerDB;integratedSecurity=true"
我添加integratedSecurity=true
是因为对SQL server的访问方法是使用Windows身份验证,而不是使用用户名和密码。当我将vanilla Java与JDBC一起使用时,它工作得很好。
然后,我定义了JDBC馈送器。
val mySQLFeeder = jdbcFeeder(databaseUrl, "", "", "SELECT * FROM [CustomerDB].[dbo].[Users]")
我在用户名和密码部分放入了空字符串,因为我没有它。
使用mvn gatling:test
运行Gatling测试,我发现这个错误是由Gatling抛出的
02:05:29.920 [ERROR] i.g.a.Gatling$ - Run crashed

因为在文档中我们应该使用用户名和密码,所以看起来Gatling JDBCFeeder方法使用integratedSecurity=true
报告了我的连接字符串。问题是在我的例子中没有用户名和密码。
有没有办法解决这个问题?
谢谢。

感谢@乔治·梁和@斯蒂芬妮·兰德尔。
该问题是由依赖项版本冲突引起的。gatling-jdbc版本必须与gatling-core版本保持一致。
将POM.xml中的依赖项更改为下面所示确实可以解决此问题。

gatling-app
包含gatling-jdbc
,所以我们不需要额外添加它。
