Question

我正在使用Apache JMeter测试我的Spring MVC Web应用程序，但我在使用h2db池连接时遇到了一些麻烦。

我的测试包括5个线程和100个循环。我在glassfish服务器上测试注册流程。首先作为数据库连接类，我使用org.springframework.jdbc.datasource.DriverManagerDataSource，但我的连接在测试过程中被暂停。现在，我使用DBCP以下参数：

<property name="initialSize" value="1"/>
<property name="maxActive" value="100"/>
<property name="maxIdle" value="10"/>

不幸的是，测试仍然暂停。我得到了：

它表明事务回滚存在一些问题。我的寄存器形式参数包含一个图像文件（34,7 kB）。在性能测试期间不应该使用这些文件吗？

有谁知道原因或解决方案？

这似乎是数据库系统错误/错误。当我使用MySQL启动相同的应用程序时，一切正常。
