错误原因
这个可能是cas 5.1.9的一个bug，后台服务器竟然没有cas-server-support-pm-jdbc:jar的5.1.9版本造成的。
解决方法也很简单，使用cas的当前最新版本，我在写本文时最新的稳定版本是5.2.5。
修改pom.xml的版本号
<properties>
<cas.version>5.2.5</cas.version>
<springboot.version>1.5.3.RELEASE</springboot.version>
<!-- app.server could be -jetty, -undertow, -tomcat, or blank if you plan to provide appserver -->
<app.server>-tomcat</app.server>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
重新打包 mvn package
就OK了
