Java Jmeter套接字连接中的TCP采样器错误

我正试图通过TCP采样器将消息从Jmeter发送到服务器 我已经在sent to message框中配置了IP、端口号和消息，然后我开始点击服务器，此时我在Jmeter中收到以下警告

015/04/17 18:00:30 WARN  - **![jmeter.protocol.tcp.sampler.TCPSampler: Could not create socket for tcp://port&IP java.net.ConnectException: Connection timed out: connect][1]**

并且让我知道Jmeter中的

TCP客户机类名

，

行尾字节

字段值

如果没有任何代码，很难确定您做错了什么，但看起来您正在传递字符串

"tcp://port&IP"

而不是像

"tcp://" + IP + ":" + port

已解决jmeter for tcp sampler配置中的套接字连接错误。当服务器未准备好接收您的请求时，将引发此异常。 所以在发送消息之前，请确认您的服务器已准备好接受请求
