很抱歉，我需要更多的信息来回答你的问题。这个错误常常是因为MyBatis无法解析映射器XML中的类型别名导致的。可能的原因包括在XML中错误地设置了类型别名或缺少必要的类型别名文件。检查一下XML配置和相关的类型别名文件是否存在问题和错误，可能有助于解决这个错误。

2023-06-08 16:13:00.035 ERROR [ aivoice-virtualnumber ] 1 --- [ main] o.s.boot.SpringApplication : Application startup failed org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'callVirtualService': Unsatisfied dependency expressed through field 'aiBoiceService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'aiBoiceService': Unsatisfied dependency expressed through field 'aiTalkRecordsService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'aiTalkRecordsService': Unsatisfied dependency expressed through field 'aiErrRecordsService'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'aiErrRecordsService': Unsatisfied dependency expressed through field 'aiWrongPoolService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'aiWrongPoolService': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'intervaTime.hour' in value "${intervaTime.hour}"

这似乎是一个应用程序启动失败的错误。根据错误信息，看起来是在创建名为 'callVirtualService' 的bean时遇到了问题，因为它的依赖项 'aiBoiceService' 无法满足。进一步检查错误信息，发现 'aiBoiceService' 的依赖项 'aiTalkRecordsService' 也无法满足，以此类推。最终，这个错误似乎与一个名为 'aiWrongPoolService' 的bean有关，因为它的某些自动装配依赖项失败了，其中包括一个名为 'intervaTime.hour' 的占位符无法解析。这可能是因为在配置文件中缺少该属性的值导致的。
