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>
