我试图弄清楚，但我不确定未发现的第二个异常是由第一个异常引起的还是配置不匹配引起的。(我正在使用Tomcat 8而不是Spring Boot使用Spring-MVC。(
如果您可以帮助我解决这个问题，我真的很感激。
您需要指定cassandra:user-type-resolver的群集bean名称，因为您正在自定义 cassandra:cluster id="cluster"中的cluster bean名称。
默认的bean名称为 cassandraCluster。将XML更改为：
<cassandra:mapping>
<cassandra:user-type-resolver keyspace-name="${cassandra.keyspace}" cluster-ref="cluster"/>
</cassandra:mapping>
为用户类型解析器设置正确的bean名称。
