分析

创建connectionFactory失败 → 创建SingleConnectionFactory失败 → 找不到JMSContext类

配置文件中，创建的是CachingConnectionFactory，它是SingleConnectionFactory的子类，而SingleConnectionFactory类中用到了一个叫JMSContext的类，现在最根本的原因就在于找不到这个类。既然以前同样的配置没问题，现在这样的配置找不到某个类，首先怀疑的就是版本问题。果然，以前的项目中用的spring4，那时候的SingleConnectionFactory并不需要JMSContext；而现在用的spring5，添加了关于这个类的返回值。JMSContext类属于javax.jms包，原来用的是1.1版本，更新成2版的即可：
