Hi,
JBoss 配置了 20 多个 Web 应用（都使用了 Spring Framework)，在 JBoss 启动的时候，在 boot.log 里面见到这 20 个都打印了一个 "[DefaultListableBeanFactory] Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory", 然后要等差不多 10 分钟才转到下一个输出，
请问可以让应用启动快一点吗？？可以禁止这些 Pre-instantiating singletons 吗？？如何配置？？
我给 JBoss 配置了 800MB 内存都搞得 Out Of Memory : Java Heap Space 了，
这个 Out Of Memory 是在初始化这些类的时候已经出现，是否与 lazy-init 配置有关？？请帮下忙。谢谢。
因为不可能每个应用都用到所有的类，所有我觉得并不需要每个应用都需要 Pre-instantiating singletons， 请问这个是否合理以及如何配置？
下面为 boot.log 里面的日志输出：

谢谢。
------解决思路----------------------
延迟初始化能行？
------解决思路----------------------
<beans default-init-lazy="true">试试懒加载初始化bean
------解决思路----------------------
延迟加载估计不靠谱。
如果你确信不是程序代码本身的问题，我很多年前碰到过tomcat出现同样的问题，
当时的解决方法是：
1. 把各个webapp里面共有的jar包放到tomcat的\common\lib下面，删除webapp各自的共有部分
2.换了jvm的实现——把sun的换成jrocket。
不知道是否有参考价值。
