Bean定义被AutoConfiguration覆盖

Question

在我的Spring应用程序中，我定义了auditListener类型的bean。

@Component
public class AuditListener {
}

// successful
beanFactory.getBean(org.springframework.boot.actuate.audit.listener.AuditListener.class);

// fails with NoSuchBeanDefinitionException
beanFactory.getBean(demo.AuditListener.class);

DefaultListableBeanFactory日志

信息10140---[main]o.s.b.f.s.DefaultListableBeanFactory：用不同的定义重写bean“Audit Listener”的bean定义：用[Root bean:class[demo.auditListener]；scope=singleton；abstract=false；lazyInit=false；autowiremode=0；dependencycheck=0；autowirecandidate=true；primary=false；factorybeanname=null；factorymethodname=null；

如何将auditlistenerbean都放到上下文中而不重命名自己的上下文？

编辑：如果我在不同的包中定义了两个具有相同类名的bean，我会得到一个冲突的BeanDefinitionException，所以ApplicationContext甚至不会启动。

您可以为bean指定一个名称，这样它就不会与springbootbean冲突

@Component(value = "myCustomAuditListener ")
public class AuditListener {
}

然后使用@qualifies按名称MyCustomAuditListener注入
