java.lang.ClassNotFoundException: javax.jms.JMSContext

對照了老師的代碼看了，啟動的時候報這個，我找了一下jar包里面確實沒有這個類，請教一下這個是什么原因呢，jar包應該不會引錯。

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]

這個問題我同樣遇到，提供一下我的解決辦法。
我使用的spring版本是5.0.4.RELEASE，activemq-core版本5.7.0。這個版本的Spring需要使用JMS 2.0版本，但spring-jms的依賴沒有自動導入JMS 2.0，而activemq-core會導入JMS 1.1的依賴，這就導致出現版本問題，

可以添加一下依賴解決，JMS 2.0 依賴如下

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

為了防止沖突，可以從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>
