Question

我的春季项目突然变得非常缓慢，无论是在启动时还是提供某种要求。我没有在web.xml \ spring-context中改变任何东西，但这一切都变得很慢。

启动从大约5秒到30秒，登录服务需要大约15秒，而在控制台弹簧似乎什么也没做。

为了更清楚，这是启动弹簧日志：

在启动过程中，内部bean实例化似乎非常慢。

07/02/2015 10:58:02 - DEBUG - (AbstractBeanFactory.java:247) - Returning cached instance of singleton bean 'lastFmController'

在spring-context.xml中，我在寻找控制器时声明要首先扫描包：

<context:component-scan base-package="org.fabrizio.lastfmmusicrecommender.controller" />

直到昨天这一切都很有效，似乎没有理由出现问题。

我还发布了web.xml \ spring-context.xml \ springmvc-servlet.xml
