Error creating bean with name 'sentinelBeanPostProcessor' defined in class path resource [com/alibaba/cloud/sentinel/custom/SentinelAutoConfiguration.class]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.baomidou.dynamic.datasource.spring.boot.autoconfigure.DynamicDataSourceAutoConfiguration': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.annotation.ProxyCachingConfiguration': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.jcache.config.ProxyJCacheConfiguration': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.transaction.annotation.ProxyTransactionManagementConfiguration': Initialization of bean failed; nested exception is java.lang.IllegalArgumentException: error at ::0 formal unbound in pointcut

这个错误是由于在创建bean时出现了问题导致的。具体来说，这个错误是由于`SentinelAutoConfiguration`类中的`sentinelBeanPostProcessor` bean的创建失败引起的。创建该bean时，发生了一个`BeanPostProcessor`实例化之前的错误。

进一步查看错误堆栈，发现了更多的错误链。其中一个是`DynamicDataSourceAutoConfiguration` bean的创建失败，另一个是`ProxyCachingConfiguration` bean的创建失败，再有一个是`ProxyJCacheConfiguration` bean的创建失败，最后一个是`ProxyTransactionManagementConfiguration` bean的初始化失败。

最后一个错误是由于在切入点表达式中存在未绑定的形式参数引起的。这可能是由于切入点表达式中使用了一个参数，但没有为其提供具体的绑定值。

要解决这个问题，你可以检查并确保以上提到的每个bean的配置正确，并且没有任何缺失或错误的配置。另外，还需要检查切入点表达式中是否存在任何未绑定的参数，并进行相应的修正。

Error creating bean with name 'dataSource' defined in class path resource [spring/spring-dao.xml]

Error creating bean with name 'dataSource' defined in class path resource [spring/spring-dao.xml]是一个Spring框架的错误。它表明在实例化bean之前，某个bean的后置处理器失败了，导致无法创建名为'dataSource'的bean。具体的错误信息是org.springframework.beans.factory.BeanCreationException: Cannot resolve reference to bean 'pt1' while setting bean property 'pointcut'。这个错误是由于在设置属性'pointcut'时，无法解析对bean 'pt1'的引用所致。进一步的错误信息是java.lang.IllegalStateException: Failed to introspect Class [org.springframework.aop.aspectj.AspectJExpressionPointcut] from ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]。这个错误是由于无法从ClassLoader [sun.misc.Launcher$AppClassLoader@18b4aac2]中内省Class [org.springframework.aop.aspectj.AspectJExpressionPointcut]所致。

根据提供的信息，可能的解决办法是：
- 检查spring-dao.xml文件中的dataSource bean的定义是否正确，确保相关的依赖项被正确引入。
- 检查是否存在名为'pt1'的bean的定义，并确保它已正确配置和初始化。
- 检查相关的类是否正确地加载到ClassLoader中，可以尝试重新编译和构建项目，确保相关的类文件和依赖项正确地放置在项目结构中。

如果问题仍然存在，可能需要进一步分析和调试来确定具体的原因和解决方法。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

Error creating bean with name 'dataSource' defined in class path resource [org/apache/ - 这个错误是在初始化bean时出现的，具体的错误信息是"nested..."。根据引用中提到的异常信息，这个错误可能是由于初始化dataSource bean时出现了问题。根据引用中提到的解决办法，可以尝试在项目的pom.xml文件中添加相应的配置，去解决找不到UserMapper.xml文件的问题。另外，引用中提到的可能是由于jar包冲突导致的问题，可以尝试删除一些冲突的jar包来解决这个问题。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
