跨线程组的java JMeter BeanShell属性设置
我试图使用BeanShell后处理器在JMeter中计算两个事件之间的时间
在第一个块中,我获取时间并将其存储为属性。这是一个线程组。 然后在另一个线程组中,我有第二个BeanShell块。我犯了一个我无法理解的错误。我已将错误粘贴到这里。非常感谢您的提示和建议
下面是两段BeanShell代码:
第一个后处理器:
//Set the current time to the time_upload variable
long time_upload = prev.getTime(); // get POST Time
props.put("time_upload",(String.valueof(time_upload)));
log.info("Time for Upload is: " + time_upload); // print difference to jmeter.log file
第二个后处理器:
String no_saved_carts = vars.get("no_saved_carts");
String no_saved_carts_trimmed = no_saved_carts.trim();
String temp_description = vars.get("description");
String temp_description_no_space = temp_description.trim();
String time_upload_local = props.get("time_upload");
if(temp_description_no_space.equals("</") || no_saved_carts_trimmed.equals("No Saved Carts Found")){
vars.put("description","true");
} else{
vars.put("description","false");
//set the time to time_processing based on time_upload
long time_processing_done = prev.getTime(); // get time
long time_upload_long = Long.parseLong(time_upload_local); // get HTTP Sampler 1 execution time from variable
long delta = (time_processing_done - time_upload); // calculate difference
log.info("Time difference is: " + delta + " ms"); // print difference to jmeter.log file
}

不能使用String将long转换为String。valueOf()方法,有以下选项:
如果仍然需要字符串,只需将行更改为将long转换为String,如下所示:
摆脱long->;字符串,反之亦然,
props
是一个常见的java.util.Properties类实例,因此它存储Objects在第一个后处理器中:
在第二个后处理器中:
你可以使用bsh.shared namespace来保存任何对象——所有线程组都可以访问它
在第一个后处理器中:
在第二个后处理器中:
您可以在jmeter中获得更多信息性错误消息。用try/catch块包围代码,记录Beanshell脚本错误时的日志文件,如:
