org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'systemApiScanController' defined in URL [jar:file:/opt/java/safety-oauth-server.jar!/BOOT-INF/lib/common-scan-starter-4.12.5.jar!/com/dpi/common/scan/controller/SystemApiScanController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'getRequestMappingScanUtils' defined in class path resource [com/dpi/common/scan/ScanAutoConfigure.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.dpi.common.scan.utils.RequestMappingScanUtils]: Factory method 'getRequestMappingScanUtils' threw exception; nested exception is java.lang.NullPointerException

这个错误是由于在创建名为'systemApiScanController'的bean时出现了依赖不满足的异常。根据异常信息，构造函数参数0存在一个未满足的依赖关系。

进一步查看异常信息，发现在类路径资源'com/dpi/common/scan/ScanAutoConfigure.class'中定义了名为'getRequestMappingScanUtils'的bean，该bean通过工厂方法创建，但在创建过程中抛出了异常。

具体来说，工厂方法'getRequestMappingScanUtils'抛出了一个java.lang.NullPointerException异常。

要解决这个问题，需要检查'getRequestMappingScanUtils'工厂方法的实现代码，并查找可能导致空指针异常的原因。可能的原因包括未正确初始化依赖对象或依赖对象为null等。

建议检查工厂方法'getRequestMappingScanUtils'中的代码，并确保所有依赖项都正确初始化，并且没有空指针异常的情况。如果有必要，还可以检查相关的配置文件和依赖项声明，以确保依赖项正确注入。

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。

这个错误提示是一个bean依赖注入失败的异常，具体的错误信息是该bean中某个属性的依赖注入失败，导致整个bean创建失败。根据错误信息可以看出是redisUtil这个bean的redisTemplate属性依赖注入失败，然后是jedisConnectionFactory的创建失败，最终是因为找不到org/bouncycastle/asn1/gm/GMNamedCurves这个类而导致的。可能是缺少相关依赖包或者版本不兼容等问题导致的。
