Spring：关于bean创建异常的Java堆空间outOfMemory

Question

我正在将我的Spring依赖注入从XML声明迁移到注释样式。

但是现在我已经迁移了DAO，服务和控制器，服务器将不再启动：

java.lang.OutOfMemoryError: Java heap space

我可以在stacktrace中看到（见下文）有一个BeanCreationException，但我不知道是哪一个，因为在BeanCreationException的消息构造中发生了OutOfMemory异常。

我已经尝试增加-Xmx和-XX：MaxPermSize JVM的参数，但我相信它就像一个无限循环或类似的东西。在迁移到注释之前，该应用程序运行良好。

您是否知道如何知道问题的来源？

版本：Hibernate 3.1，Spring 2.5，Tomcat 7，JDK 7

典型的applicationContext.xml内容（之前）：

<bean id="fooDAO" class="foo.bar.fooDAO">
    <property name="sessionFactory">
        <ref bean="foo_factory" /> //extends LocalSessionFactoryBean
    </property>
</bean>

<bean id="fooService" class="foo.bar.fooService">
    <property name="foodDAO" ref="fooDAO" />
</bean>

<bean id="fooControler" class="foo.bar.fooControler" autowire="byName">
     <property name="fooService" ref="fooService" />
</bean>

迁移后：

DAO上的@Repository，服务上的@Service和控制器上的@Controller。
