在jmeter中运行bean脚本时无法导入com.paytm.merchant.CheckSumServiceHelper [英] Not able to import com.paytm.merchant.CheckSumServiceHelper when running beanshell script in jmeter
问题描述
我是Jmeter的JSR223预处理程序的新手.我们刚刚将Paytm的支付网关集成到了我们的产品中，我们不得不使用Jmeter运行负载测试.我们必须使用一组值生成一个校验和，然后将其注入到我们的Json有效负载中.我正在使用Java Beanshell执行代码.我在bin目录中添加了此处可用的jar文件，并将其添加到我的类路径中在开始测试之前.这是我的代码:
I am new to Jmeter's JSR223 PreProcessor. We have just integrated Paytm's payment gateway into our product and we had to run load tests using Jmeter. We have to generate a checksum using a set of values and then inject that into our Json payload. I am using Java Beanshell to execute the code. I have added the jar file available here in my bin directory and also added it to my class path before starting the tests. Here is what my code looks like:
import com.paytm.merchant.CheckSumServiceHelper;
com.paytm.merchant.CheckSumServiceHelper checkSumServiceHelper = com.paytm.merchant.CheckSumServiceHelper.getCheckSumServiceHelper();
TreeMap<String,String> parameters = new TreeMap<String,String>();
String merchantKey = "xxxxxxxxxxxxxxxxx";
parameters.put("MID", "xxxxxxxxxxxxxxxxxxxxxx");
parameters.put("ORDERID", "${orderId}");
parameters.put("TXNID", "20200113111212800110168201701179744");
parameters.put("TXN_AMOUNT", "10.01");
parameters.put("PAYMENTMODE", "DC");
parameters.put("CURRENCY", "INR");
parameters.put("TXNDATE", "2020-01-13 13:59:03.0");
parameters.put("STATUS", "TXN_SUCCESS");
parameters.put("RESPCODE", "01");
parameters.put("RESPMSG", "Txn Success");
parameters.put("GATEWAYNAME", "HDFC");
parameters.put("BANKTXNID", "777001911059826");
parameters.put("BANKNAME", "JPMORGAN CHASE BANK");
parameters.put("BANKNAME", "JPMORGAN CHASE BANK");
String checkSum = checkSumServiceHelper.genrateCheckSumGAE(merchantKey, parameters);
vars.put("checkSum", checkSum)
这是我得到的错误:
javax.script.ScriptException: Sourced file: inline evaluation of: ``import com.paytm.merchant.CheckSumServiceHelper; com.paytm.merchant.CheckSumSer . . .

对于解决此错误的任何帮助，我们将不胜感激.这可能是一个愚蠢的问题，但是我对此并不陌生，所以请帮忙！ :)
Any kind of help to resolve this error will be highly appreciated. It might be a stupid question but I am new to this so please help!! :)
我现在正在使用groovy语法来做到这一点.我无法使用调试采样器在查看结果树"中查看我的校验和变量，但可以在控制台中看到它.该值在控制台中正确显示.但是该变量未导出.
I am now using the groovy syntax for doing this. I am not able to view my checksum variable in View Results Tree with my debug sampler but I am able to see it in the console. The value is shown correctly in console. But the variable is not being exported.
import com.paytm.pg.merchant.CheckSumServiceHelper;
com.paytm.pg.merchant.CheckSumServiceHelper checkSumServiceHelper = com.paytm.pg.merchant.CheckSumServiceHelper.getCheckSumServiceHelper();
TreeMap parameters = new TreeMap();
String merchantKey = "xxxxxxxxxxxxxxxxx";
parameters.put("MID", "xxxxxxxxxxxxxxxxxxxxxx");
parameters.put("ORDERID", "${orderId}");
parameters.put("TXNID", "20200113111212800110168201701179744");
parameters.put("TXN_AMOUNT", "10.01");
parameters.put("PAYMENTMODE", "DC");
parameters.put("CURRENCY", "INR");
parameters.put("TXNDATE", "2020-01-13 13:59:03.0");
parameters.put("STATUS", "TXN_SUCCESS");
parameters.put("RESPCODE", "01");
parameters.put("RESPMSG", "Txn Success");
parameters.put("GATEWAYNAME", "HDFC");
parameters.put("BANKTXNID", "777001911059826");
parameters.put("BANKNAME", "JPMORGAN CHASE BANK");
parameters.put("BANKNAME", "JPMORGAN CHASE BANK");
String checkSum = checkSumServiceHelper.genrateCheckSumGAE(merchantKey, parameters);
Out. println "s====================================ssssss"
OUT. println checkSum
props.put("checkSum", checkSum);
这是我执行此操作时出现的错误:
Here is the error when I run this:
javax.script.ScriptException: javax.script.ScriptException: java.security.InvalidKeyException: Invalid AES key length: 17 bytes
我认为此错误是由于我的输入值引起的.
I think this error is due to my input values.
推荐答案
Beanshell 不是Java，它也是并非100％与Java兼容，您需要坚持
Beanshell is not Java and it isn't 100% compliant with Java, you need to stick to Java 1.5 language level in general.
尤其是Beanshell不支持钻石运算符 ，您需要将其从代码中删除，例如:
In particular Beanshell doesn't support Diamond Operators, you need to remove them from your code like:
TreeMap parameters = new TreeMap();
通常从JMeter 3.1开始，建议使用JSR223测试元素和Groovy脚本语言，原因在:
In general starting from JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting, the reasons are in:
- 可以在每次调用Beanshell时对Groovy脚本进行编译和缓存，因此Groovy的性能要高得多
- Groovy支持所有基础 JDK语言功能，而Beanshell卡在Java 5中
- 此外， Groovy与常规Java SDK相比提供了许多增强功能
- Groovy scripts can be compiled and cached while Beanshell is being evaluated each time it's called hence Groovy performance is much higher
- Groovy supports all underlying JDK language features while Beanshell got stuck at Java 5
- In addition Groovy provides a lot of enhancements over normal Java SDK
