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。

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'es8Client'

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'es8Client'是指在创建名为'es8Client'的Bean时出现了异常。
根据引用和引用的描述，可能是因为在工程启动时实例化ClientDetailsService类Bean时出现了异常。这可能是由于Seata框架的引入导致的，它在工程启动时会扫描到该Bean的方法触发方法执行，但是没有找到对应的Bean，或者找到了一个虚假的Bean，从而导致异常抛出。

根据引用的描述，可能是因为默认方法无法创建ClientDetailsService类Bean。Spring Cloud Oauth2框架中创建ClientDetailsService类默认Bean的方法是一个“假方法”，执行后并无法创建ClientDetailsService类Bean，而是固定抛出操作不支持异常。建议使用内存或JDBC方式配置客户端。

解决方案是根据具体情况进行调试和修复。可能需要确认是否正确配置了Seata框架，并检查是否存在与'es8Client'相关的Bean定义或配置问题。还可以尝试使用内存或JDBC方式配置客户端来解决问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
