我定义了以下 Spring Bean：

<bean id="grantingTicketExpirationPolicy" class="org.jasig.cas.ticket.support.TicketGrantingTicketExpirationPolicy"
      c:maxTimeToLive="${tgt.maxTimeToLiveInSeconds:32400}" c:timeToKill="${tgt.timeToKillInSeconds:32400}" c:timeUnit-ref="SECONDS" />

那对应于这个 bean。使用上述配置，我得到以下异常：

SEVERE: Exception starting filter springSecurityFilterChain
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'grantingTicketExpirationPolicy' defined in ServletContext resource [/WEB-INF/spring-configuration/ticketExpirationPolicies.xml]: Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

    at java.lang.Thread.run(Thread.java:745)

所以我所做的就是从这个示例文件中复制并更改：

<bean id="grantingTicketExpirationPolicy" class="org.jasig.cas.ticket.support.TicketGrantingTicketExpirationPolicy"
      c:maxTimeToLive="${tgt.maxTimeToLiveInSeconds:28800}" c:timeToKill="${tgt.timeToKillInSeconds:7200}" c:timeUnit-ref="SECONDS" />

至：

<bean id="grantingTicketExpirationPolicy" class="org.jasig.cas.ticket.support.TicketGrantingTicketExpirationPolicy"
      c:maxTimeToLive="${tgt.maxTimeToLiveInSeconds:32400}" c:timeToKill="${tgt.timeToKillInSeconds:32400}" c:timeUnit-ref="SECONDS" />

我哪里错了？

带有您正在使用的参数的构造函数可能不存在。查看TicketGrantingTicketExpirationPolicy可用的构造函数并进行相应调整。
