介绍
抛出该异常的地方并不能找到根本原因，需要耐心详细查看下日志。
异常情况
No bean named '✘✘✘✘✘✘✘.importRegistry' available异常报出如下:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'masterTransactionManager' defined in class path resource [com/qx/boot/db/MybatisConfigurer.class]: BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.cache.annotation.ProxyCachingConfiguration': Initialization of bean failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'org.springframework.context.annotation.ConfigurationClassPostProcessor.importRegistry' available

从这里面我们似乎看不到什么具体问题,那么我们接着往下看日志报出的异常,看如下报出的异常:

从上面我们可以看到org.springframework.boot.web.servlet.context.AnnotationConfigServletWebServerApplicationContext@271f18d3has not been refreshed yet，那么是不是ApplicationCOntext.refresh()报出了异常，我们来具体查看下源码:
@Override
public void refresh() throws BeansException, IllegalStateException {
synchronized (this.startupShutdownMonitor) {
// Prepare this context for refreshing.
prepareRefresh();
// Tell the subclass to refresh the internal bean factory.
ConfigurableListableBeanFactory beanFactory = obtainFreshBeanFactory();
// Prepare the bean factory for use in this context.
prepareBeanFactory(beanFactory);
try {
// Allows post-processing of the bean factory in context subclasses.
postProcessBeanFactory(beanFactory);
// Invoke factory processors registered as beans in the context.
invokeBeanFactoryPostProcessors(beanFactory);
// Register bean processors that intercept bean creation.
registerBeanPostProcessors(beanFactory);
// Initialize message source for this context.
initMessageSource();
// Initialize event multicaster for this context.
initApplicationEventMulticaster();
// Initialize other special beans in specific context subclasses.
onRefresh();
// Check for listener beans and register them.
registerListeners();
// Instantiate all remaining (non-lazy-init) singletons.
finishBeanFactoryInitialization(beanFactory);
// Last step: publish corresponding event.
finishRefresh();
}
catch (BeansException ex) {
if (logger.isWarnEnabled()) {
logger.warn("Exception encountered during context initialization - " +
"cancelling refresh attempt: " + ex);
}
// Destroy already created singletons to avoid dangling resources.
destroyBeans();
// Reset 'active' flag.
cancelRefresh(ex);
// Propagate exception to caller.
throw ex;
}
finally {
// Reset common introspection caches in Spring's core, since we
// might not ever need metadata for singleton beans anymore...
resetCommonCaches();
}
}
}
找到该方法打印异常日志的地方,异常打印关键字:Exception encountered during context initialization,这个异常会打印出具体的异常信息。
解决
发现异常抛出的地方，那就好解决了,我们在异常日志中搜索该关键字Exception encountered during context initialization关键字,就会找到具体发生错误的bean。
