Error creating bean with name 'eurekaAutoServiceRegistration'

org.springframework.beans.factory.BeanCreationNotAllowedException: Error creating bean with name 'eurekaAutoServiceRegistration': Singleton bean creation not allowed while singletons of this factory are in destruction (Do not request a bean from a BeanFactory in a destroy method implementation!)

上面這個異常，我這邊是端口號占用了。 換個端口號就可以。

還有，可以根據棧信息排查下。  從下往上看，可以看到，項目啟動時

 //這里將bean 銷毀 destroy
 at org.springframework.context.support.AbstractApplicationContext.destroyBeans(AbstractApplicationContext.java:1032)

然后繼續往上看 

//這里getBean 
at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1080)

這個錯誤就發生在從容器中獲取單例bean的時候

//獲取單例bean 
at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:216)

源碼：

    public Object getSingleton(String beanName, ObjectFactory<?> singletonFactory) {
        Assert.notNull(beanName, "'beanName' must not be null");
        synchronized (this.singletonObjects) {
            Object singletonObject = this.singletonObjects.get(beanName);
            if (singletonObject == null) {
                if (this.singletonsCurrentlyInDestruction) {
                    throw new BeanCreationNotAllowedException(beanName,
                            "Singleton bean creation not allowed while singletons of this factory are in destruction " +
                            "(Do not request a bean from a BeanFactory in a destroy method implementation!)");
                }
                if (logger.isDebugEnabled()) {
                    logger.debug("Creating shared instance of singleton bean '" + beanName + "'");
                }
