使用jar但不在库中时出错

ibm-mq java

Royce · 技术社区 · 6 年前

我构建了一个Java库来在IBM MQ中发送消息。

当我在库项目上执行代码时,它工作得很好。

.jar 在另一个工具(JMeter)中,会发生错误。

java.lang.NoSuchMethodError: com.ibm.mq.jmqi.JmqiFactory.getInstance(Lcom/ibm/mq/jmqi/JmqiThreadPoolFactory;Lcom/ibm/mq/jmqi/JmqiPropertyHandler;)Lcom/ibm/mq/jmqi/JmqiEnvironment;

对应代码:

MQConnectionFactory factory = new MQConnectionFactory();
factory.setHostName(properties.getProperty("HOST"));
factory.setPort(Integer.parseInt(properties.getProperty("PORT")));
factory.setChannel(properties.getProperty("CHANNEL"));
factory.setTransportType(WMQConstants.WMQ_CM_CLIENT);
factory.setQueueManager(properties.getProperty("QUEUE_MANAGER"));
factory.setAppName(properties.getProperty("APP_NAME"));
Connection connection = factory.createConnection(properties.getProperty("APP_USER"), properties.getProperty("APP_PASSWORD"));
connection.start();
return connection;

MQConnectionFactory factory = new MQConnectionFactory();

知道吗?谢谢您。

更新1

.jar文件 一:

点击 Export
挑选出来的 Runnable JAR file
Extract required libraries into generated JAR

更新2

此外,当我建造罐子,我得到这个警告。你认为那很重要吗?

此操作重新打包引用库。请检查与您希望参考的库相关联的许可证,以确保您能够使用此应用程序重新打包它们。还要注意,此操作不会将签名文件从原始库复制到生成的JAR文件。

在与 OP 我亲自去核实了这个问题。结果是它对我有用。。。

创建了一个包含以下代码的maven项目

package test;

import javax.jms.JMSException;
import com.ibm.mq.jms.MQConnectionFactory;

public class JmeterTest {

    public JmeterTest() {
    }

    public void test() throws JMSException {
        MQConnectionFactory factory = new MQConnectionFactory();
        factory.setAppName("myApp");
    }

    public static void main(String[] args) {
        System.out.println("test");
    }
}

步骤2: 从eclipse将其导出为runnable jar并复制到JMeter中( \lib\ext\

注意,带有库处理的导出 package required jars into generated jar 不起作用。使用 Extract into generated jar Copy into subfolder (然后将jars从子文件夹复制到 \lib\ext
