我正在针对带有Gatling的IBM MQ实施负载测试场景。 设置与提到的here
基本相同问题：我无法使用IBM MQ初始化所需的ContextFactory - 应该是com.ibm.mq.jms.context.WMQInitialContextFactory。
无法找到WMQInitialContextFactory。
但我的build.sbt正确包含IBM MQ依赖项（由我们的内部Nexus成功检索：
"com.ibm.mq" % "com.ibm.mq" % "8.0.0.3"
我的情节：
package com.myawesomecompany.loadtest
import com.ibm.mq._
import com.ibm.mq.jms.MQConnectionFactory
import com.ibm.mq.jms.JMSMQ_Messages
import com.ibm.msg.client.wmq.common.CommonConstants
import io.gatling.core.Predef._
import io.gatling.core.scenario.Simulation
import io.gatling.jms.Predef._
import javax.jms._
import scala.concurrent.duration._
class JMSLoadTest extends Simulation {
val jmsConfiguration = jms
.connectionFactoryName("ConnectionFactory")
.url("devmq01.company.dmz")
.credentials("mqm", "mqm")
.contextFactory(classOf[com.ibm.mq.jms.context.WMQInitialContrextFactory].getName)
.listenerCount(1)
.usePersistentDeliveryMode
val scn = scenario("Load testing GPRSForwarder").repeat(1) {
exec(jms("testing GPRSForwarder...").reqreply
.queue("COMPANY.TEST.QUEUE")
.textMessage("00001404020611100E033102C20EBB51CC1C036EFFFF00010002323802000200FE05001400000000FFFFFFFFFFFFFFFFFF040010038B0D6912EB10CE070206110F37298C")
.jmsType("test_jms_type")
)
}
setUp(scn.inject(rampUsersPerSec(10) to 1000 during (2 minutes)))
.protocols(jmsConfiguration)
}
设置相当于this one - 但我没有使用ActiveMQInitalContextFactory，而是强行使用＆＃34;对应＆＃34; IBM MQ。
根据official docks，WMQInitialContextFactory应该在com.ibm.mq.jms.context，但事实并非如此。矿石在CommonConstants中有一些常数，我可以用来初始化ContextFactory吗？
提前多多感谢。

问题：我无法初始化所需的ContextFactory IBM MQ - 应该是 com.ibm.mq.jms.context.WMQInitialContextFactory。该 找不到WMQInitialContextFactory。
不要使用WMQInitialContextFactory。这是一个MQ SupportPac创建者，他们希望将MQ用作JNDI存储库。这不是一个好主意，而且SupportPac不支持任何形式的安全性（即SSL / TLS或安全性退出）。
您应该使用基于文件的MQ JNDI。这是一个基本的例子：
import java.util.Hashtable;
import javax.jms.JMSException;
import javax.jms.Queue;
import javax.jms.QueueConnection;
import javax.jms.QueueConnectionFactory;
import javax.jms.QueueSender;
import javax.jms.QueueSession;
import javax.jms.Session;
import javax.jms.TextMessage;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.ibm.mq.MQException;
