java - 如何使用 JMeter 记录 JNLP/Java Web Start 应用程序

Question

我需要对 JNLP 可访问应用程序进行性能测试。

我使用了 WireShark，发现 jnlp 只生成 TCP 流量。

我阅读了所有与 jnlp 性能测试相关的帖子，并尝试使用Apache JMeter + UbikLoadPack Java 序列化插件，但 jmeter 没有捕获流量。

这是我唯一的选择捕获 TCP 流量并使用它吗？

问候，詹姆

Answer 1

If traffic is HTTP(s), as per documentation of UbikLoadPack bundle, You need to follow the instructions of paragraphs:

1/Add JMeter certificate authority to the cacerts file used by Java:

See in documentation "Configuring Application for HTTPS" (Pages 7/8). This will allow your application to work when using JMeter as proxy if traffic is HTTPS

Steps are the following:

• Start JMeter

• Use File > Templates... Menu item, then select "Recording" Template and click Create

• Start HTTP(S) Test Script Recorder by clicking on Start Button

• JMeter will generate a Certificate Authority in 2 formats in jmeter/bin folder:

  • ApacheJMeterTemporaryRootCA.crt
  • ApacheJMeterTemporaryRootCA.usr
• Find cacerts file used by your system, it should be in JAVA_HOME/jre/lib/security/cacerts
• Run:

keytool -keystore cacerts -importcert -alias jmeter_ca -file <path to jmeter>/bin/ApacheJMeterTemporaryRootCA.crt

• keystore password is usually "changeit"
• enter "yes" for "Trust this certificate?" question

2/To set JMeter as proxy of JNLP:

• Open the Java Control Panel

• Click Network Settings. The Network Settings dialog box opens.

• Select Use proxy server, enter the proxy server name (localhost), and port number (8888 for JMeter).

• Click Advanced and check "Use same proxy server for all protocols":

- Click Apply - Restart your application again

See reference documentation:

• https://docs.oracle.com/javase/7/docs/technotes/guides/jweb/networking/proxie_config.html
• Force java web start to use a proxy like Fiddler without touching code

If it’s not HTTP, the plugin does not support it.
