从 Java 代码调用时 Jmeter 函数不执行 [英] Jmeter functions don't executing when calling from java code

问题描述

我在我的 jmx 文件中使用了一些 jmeter 函数.当我用jmeter工具从命令行运行它时，它运行正常，执行函数并返回一个值.

I'm using some jmeter functions in my jmx file. When I run it from command line with jmeter tool, its running normally, executing the function and return a value.

当我运行加载相同 jmx 文件的 java 代码时，它会将函数作为字符串并且不返回值.

When I run the java code , which load the same jmx file its taking a function as a string and don't return a value.

我测试了几个函数，结果都是一样的.在 jtl 文件中，我看到类似这样的内容 - ${__time(yyyy-MM-dd HH:mm:ss)}

I have tested with several functions, Results are the same. In jtl file I see something like this- ${__time(yyyy-MM-dd HH:mm:ss)}

<httpSample t="663" it="0" lt="631" ts="1492989803759" s="true" lb="User-getapikey   ${__time(yyyy-MM-dd HH:mm:ss)} " rc="200" rm="" tn="Thread Group 1-1" dt="text" de="UTF-8" by="528" ng="1" na="1">

这是我的java代码，当我没有函数时它正常工作:

Its my java code, its working normally when I don't have a functions:

StandardJMeterEngine jmeter = new StandardJMeterEngine();
JMeterUtils.loadJMeterProperties(jmeterPropertiesPath);
JMeterUtils.setJMeterHome(jmeterHomePath);
JMeterUtils.initLogging();
JMeterUtils.initLocale();

SaveService.loadProperties();
HashTree testPlanTree = null;
                try{
                    log.info("loading testPlanTree");
                    testPlanTree = SaveService.loadTree(jmxFile);
                    JMeter.convertSubTree( testPlanTree );
                }catch(IOException ex){
                    log.info("error loading file as tree");
                    log.info(ex.getMessage());
                    return;
                }
                jmeter.configure(testPlanTree);
                jmeter.run();

推荐答案

您的代码看起来不错，只需仔细检查您的项目类路径中是否有 ApacheJMeter_functions.jar.该文件位于 JMeter 安装的lib/ext"文件夹下.

Your code looks good, just double check you have ApacheJMeter_functions.jar in your project classpath. The file is located under "lib/ext" folder of your JMeter installation.

您可能还想添加 ResultCollector将您的测试执行结果存储到 .jtl 文件中，例如:

You might also want to add ResultCollector to store your test execution results into .jtl file like:

Summariser summer = null;
String summariserName = JMeterUtils.getPropDefault("summariser.name", "summary");
if (summariserName.length() > 0) {
    summer = new Summariser(summariserName);
}

ResultCollector logger = new ResultCollector(summer);
logger.setFilename("result.jtl");
testPlanTree.add(testPlanTree.getArray()[0], logger);
