启动spring 报错:
BeanFactory not initialized or already closed call ‘refresh‘ before accessing beans via the ApplicationContext
此错误是由AbstractRefreshableApplicationContext#getBeanFactory方法中抛出来的.
@Override
public final ConfigurableListableBeanFactory getBeanFactory() {
synchronized (this.beanFactoryMonitor) {
if (this.beanFactory == null) {
throw new IllegalStateException("BeanFactory not initialized or already closed - " +
"call ‘refresh‘ before accessing beans via the ApplicationContext");
}
return this.beanFactory;
}
}
是因为在Spring在解析xml时出错, 导致close方法被调用, 而在close方法调用链上包括getBeanFactory.
详解:
方法一:
protected final void closeBeanFactory() {
...
this.beanFactory = null;
}
方法二:
protected final void refreshBeanFactory() throws BeansException {
...
closeBeanFactory();
DefaultListableBeanFactory beanFactory = createBeanFactory();
...
loadBeanDefinitions(beanFactory); // 加载bean定义(解析xml文件)
...
this.beanFactory = beanFactory;
}
由方法一,二可知: 当加载bean定义(解析xml文件)出错时, AbstractRefreshableApplicationContext中的变量beanFactory为null.
方法三:
public void close() {
...
doClose();
...
}
方法四:
protected void doClose() {
...
destroyBeans();
...
}
方法五:
protected void destroyBeans() {
getBeanFactory().destroySingletons();
}
由方法三,四,五可知: ApplicationContext的close方法被调用时,会调用getBeanFactory(), 这时beanFactory为null.
close最终是被ContextLoaderListener#contextDestroyed所调用.BeanFactory not initialized or already closed exception
