java.lang.ClassNotFoundException: javax.jms.JMSContext

对照了老师的代码看了，启动的时候报这个，我找了一下jar包里面确实没有这个类，请教一下这个是什么原因呢，jar包应该不会引错。

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'connectionFactory': Lookup method resolution failed; nested exception is java.lang.IllegalStateException: Failed to introspect Class [org.springframework.jms.connection.SingleConnectionFactory] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]

这个问题我同样遇到，提供一下我的解决办法。
我使用的spring版本是5.0.4.RELEASE，activemq-core版本5.7.0。这个版本的Spring需要使用JMS 2.0版本，但spring-jms的依赖没有自动导入JMS 2.0，而activemq-core会导入JMS 1.1的依赖，这就导致出现版本问题，

可以添加一下依赖解决，JMS 2.0 依赖如下

<dependency>
    <groupId>javax.jms</groupId>
    <artifactId>javax.jms-api</artifactId>
    <version>2.0.1</version>
</dependency>

为了防止冲突，可以从activemq-core中去除JMS 1.1，pom 如下所示

<dependency>
    <groupId>org.apache.activemq</groupId>
    <artifactId>activemq-core</artifactId>
    <version>5.7.0</version>
    <exclusions>
        <exclusion>
            <artifactId>spring-context</artifactId>
            <groupId>org.springframework</groupId>
        </exclusion>
        <exclusion>
            <groupId>org.apache.geronimo.specs</groupId>
            <artifactId>geronimo-jms_1.1_spec</artifactId>
        </exclusion>
    </exclusions>
</dependency>
