出现如上的错误,解决方案有两种

1.给你被代理的类实现一个接口.

2.加上cglib的jar 包

1、IOC容器的设计思想 IOC容器的核心是依赖注入 + 控制反转，即将代码中手动创建对象的过程交给spring来管理，对象的生命周期也是spring管理的； 2、spring的作用域 scope决定着spring是单例模式还是多例模式，如果是单例模式，在spring的ioc容器中只允许有一个这种对象，然后第二次创建，会先看容器里面有没有这个对象，如果有不会新建 基本只用单例模式，少数用多例模式，其他三种基本不用； 3、spring常见的注入方式 注入方式在autow.

本文介绍了Spring Cloud Hystrix框架在微服务架构中的应用，重点讲解了其通过熔断器、线程池隔离和降级策略等机制，提升系统的容错性和稳定性。Hystrix能够有效防止服务故障的连锁反应，确保系统的高可用性。通过对Hystrix的基本原理和实际应用的解析，本文为开发者提供了在分布式系统中实现错误处理和系统容错的思路。尽管新技术如Resilience4j逐步替代了Hystrix，但它依然是微服务容错设计的经典实践。
