用@Component 注解的类, 加载时spring 报 org.springframework.beans.factory.NoSuchBeanDefinitionException: No qu

异常说明:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.baixun.manage.schedule.manage.VersionThread' available

最后一个参考, spring 注入多线程实现类

报错环境:

类对象时一个继承 Thread 的类,用 @Component 注解了,不存在注解扫描路径的问题,在 用 BeanFactory 加载该类时报错,一直无法理解,后来发现 Spring 默认注册都是单例模式,无法直接加载 多线程类,必须用@Scope("prototype") 指定范围,

后来再用benaFactory 生成类对象时,又报异常

org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'versionThread' is expected to be of type 'com.baixun.manage.schedule.manage.VersionThread' but was actually of type 'com.sun.proxy.$Proxy190'
	at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:378) ~[spring-beans-4.3.13.RELEASE.jar:4.3.13.RELEASE]

生成的时代理类型,可能时@Scope("prototype") 指定的原型,所以生成的类,会自动变成代理类,

在类上加 @

@EnableAspectJAutoProxy(proxyTargetClass=true)   // 设置允许使用 代理类型
