[seata]GlobalTransactionScanner#wrapIfNecessary在springboot3下无法代理导致启动失败

环境：

**JDK：17 springboot：3.0.5 springcloud: 2022.0.2 springcloud-alibaba:2022.0.0.0-RC1

seata-all：1.6.1**

问题描述：

启动微服务客户端报错（集成了）

java.lang.reflect.InaccessibleObjectException: Unable to make field protected java.lang.reflect.InvocationHandler java.lang.reflect.Proxy.h accessible: module java.base does not "opens java.lang.reflect" to unnamed module

在getBean初始化调用applyBeanPostProcessorsAfterInitialization时如果当前类为代理类（已被AnnotationAwareAspectJAutoProxyCreator#applyBeanPostProcessorsAfterInitialization增强过）调用GlobalTransactionScanner#applyBeanPostProcessorsAfterInitialization再次代理时通过SpringProxyUtils.findInterfaces获取接口信息（内部getAdvisedSupport会反射protected java.lang.reflect.InvocationHandler java.lang.reflect.Proxy.h）调用h.setAccessible(true); 即出现jdk模块化后无法直接反射内部模块错误

期望解惑

目前我手动注入了GlobalTransactionScanner并设置了Order为最高优先级，让GlobalTransactionScanner在AnnotationAwareAspectJAutoProxyCreator执行后就不不会出现该问题；

希望能告知此问题产生的原因；如果不是bug：我该怎么解决这个问题
我这个解决方案有效吗，会影响事务内部代理的机制不

谢谢各位~

“集成了“，那里我想说的是nacos、sentinel、dynamic-datasource、mybatis-plus来着

ForJ-W

例如mybatis mapper代理类被jdk aop代理过一次然后GlobalTransactionScanner再次代理时

执行AbstractAutowireCapableBeanFactory#applyBeanPostProcessorsAfterInitialization
执行AnnotationAwareAspectJAutoProxyCreator#postProcessAfterInitialization
执行GlobalTransactionScanner#postProcessAfterInitialization

执行SpringProxyUtils#findInterfaces出现以下异常

将以上BeanPostProcessor（第二步第三步）调换就没有这个问题：

执行AbstractAutowireCapableBeanFactory#applyBeanPostProcessorsAfterInitialization
执行GlobalTransactionScanner#postProcessAfterInitialization
执行AnnotationAwareAspectJAutoProxyCreator#postProcessAfterInitialization
执行SpringProxyUtils#findInterfaces出现以下异常

1.7.0-native-rc2版本修复了SpringProxyUtils#getAdvisedSupport

我也遇到这个问题了，终于解决了，谢谢楼主老哥。
