错误处理：java.lang.NoClassDefFoundError: javax/jms/JMSContext

原因是少包，需要在pom文件增加依赖

<dependency>

    <groupId>javax.jms</groupId>

    <artifactId>javax.jms-api</artifactId>

    <version>2.0.1</version>

</dependency>

子工程引入：

        <!--activemq-all-->

        <dependency>

            <groupId>org.apache.activemq</groupId>

            <artifactId>activemq-all</artifactId>

        </dependency>

        <!--必须引入，否则会提示错误java.lang.ClassNotFoundException: javax.jms.JMSContext-->

        <!-- https://mvnrepository.com/artifact/javax.jms/javax.jms-api -->

        <dependency>

            <groupId>javax.jms</groupId>

            <artifactId>javax.jms-api</artifactId>

        </dependency>
