这个异常信息看起来像是在 Spring Boot 应用程序中使用 Spring Security 进行 OAuth2 认证时出现的问题。具体而言，它可能表示在配置 Resource Server 时出现了依赖项不满足的问题，其中一个依赖项是 PigAccessDeniedHandler，可能由于无法实例化该类而导致。更具体地说，它可能是由于 PigAccessDeniedHandler 依赖于一个无法实例化的工厂方法 pigAccessDeniedHandler 引起的，其中该工厂方法调用了一个 null 值的方法 com.sun.xml.bind.v2.runtime.reflect.opt.Injector.defineClass。要解决此问题，您可以检查应用程序的配置和依赖项，确保它们正确地设置和配置。另外，您可能需要检查 PigAccessDeniedHandler 和 pigAccessDeniedHandler 的实现代码，以确定是否有任何错误或缺失的依赖项。如果您不确定如何解决问题，请提供更多上下文信息或更多详细信息，我会尽力帮助您解决问题。

这个异常信息看起来像是在运行 Spring Boot 应用程序时发生的。具体而言，它可能表示在应用程序启动过程中出现了某些问题，可能是由于依赖项不满足或配置错误所致。在这种情况下，您可能需要检查应用程序的配置和依赖项，以确保它们正确地设置和配置。如果您不确定如何解决问题，请提供更多上下文信息或更多详细信息，我会尽力帮助您解决问题。

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。
