jmeter压测报java.net.SocketException: Connection reset

Posted 2023-04-10 测试界的飘柔

最近在压测的过程中，聚合报告中存在错误，1000个并发，错误率为2.几，本以为是系统接口的问题。后来查看资料发现，是本地配置导致

通过查看结果树发现，响应数据报java.net.SocketException: Connection reset

根据网上资料是如下解决的

解决办法：

新建txt,保存以下脚本修改后缀为reg文件，编辑值如下，保存后双击执行；重启电脑，再次压测即不会出现报错。

解析中值为10进制，下方脚本已全转换为16进制。

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters]

“MaxUserPort”=dword:fffe

“TcpTimedWaitDelay”=dword:1e

“TcpNumConnections”=dword:fffffe

“MaxFreeTcbs”=dword:7D0

“MaxHashTableSize”=dword:10000

需要调整的值：
MaxUserPort：最大动态端口数（Default = 5000, Max = 65534）
TcpTimedWaitDelay：TCP等待延迟时间（30）
TcpNumConnections：TCP最大连接数（Default = 16,777,214）
MaxFreeTcbs：最大TCP控制块（1000-2000）
MaxHashTableSize：最大TCB Hash table数量（64-65536）
解析中值为10进制，下方脚本已全转换为16进制

实际在注册表新增：
[HKEY_LOCAL_MACHINE\\SYSTEM\\CurrentControlSet\\Services\\Tcpip\\Parameters]
“MaxUserPort”=dword:fffe
“TcpTimedWaitDelay”=dword:1e
“TcpNumConnections”=dword:fffffe
“MaxFreeTcbs”=dword:7D0
“MaxHashTableSize”=dword:10000

原因：
由于 JDK 8 中有关反射相关的功能自从 JDK 9 开始就已经被限制了，为了兼容原先的版本，需要在运行项目时添加 --add-opens java.base/java.lang=ALL-UNNAMED 选项来开启这种默认不被允许的行为。

解决方案：

修改 apache-jmeter-5.4.3\\bin\\jmeter.bat 文件的112行，添加在 JAVA9_OPTS 那里添加 --add-opens java.desktop/sun.awt.shell=ALL-UNNAMED

环境变量问题

现在版本的jmeter不用再配置系统环境变量了。如果报如下错误，说明配置 JMETER_BIN 时，没有以反斜杠结尾
