错误日志如下：直接停止启动，无详细错误信息日志。

解决方案：

在org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory类中的所有catch (xxxException e)打断点，所有捕获异常的地方全部打上断点，终于看到了错误信息。

很显然这是Spring的锅，有错误凭什么不打出来错误日志！！！！！！

周末有空仔细看看给Spring提个issues！

如果Mybatis有类似的问题，可在找到`org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory` 类中所有catch (xxxException e)处打断点解决问题。

不报错的原因是错误被吞掉了，没抛给调用方。

protected Class<?> getTypeForFactoryBean(String beanName, RootBeanDefinition mbd) {
        if (!mbd.isSingleton()) {
            return null;
        }
        try {
            FactoryBean<?> factoryBean = doGetBean(FACTORY_BEAN_PREFIX + beanName, FactoryBean.class, null, true);
            return getTypeForFactoryBean(factoryBean);
        }
        catch (BeanCreationException ex) {
            // Can only happen when getting a FactoryBean.
            if (logger.isDebugEnabled()) {
                logger.debug("Ignoring bean creation exception on FactoryBean type check: " + ex);
            }
            onSuppressedException(ex);
            return null;
        }
    }
