死锁问题 org.springframework.cloud.context.scope.GenericScope$LockedScopedProxyFactoryBean.invoke(GenericScope.java:478)

[Johnson-Jia]

程序运行一段时间后，所有线程都卡在 org.springframework.cloud.context.scope.GenericScope.LockedScopedProxyFactoryBean#invoke 方法 478行。

使用的是：
JDK 21

spring-boot 3.2.12
spring-cloud-starter 4.1.4
spring-cloud-context-4.1.4

spring-cloud-starter-alibaba-nacos-config 2023.0.3.3
spring-alibaba-nacos-config 2023.0.3.3

dubbo-spring-boot-starter 3.3.5

PlanCourseSchemeServiceImpl 类增加了 @RefreshScope 注解。
