Question

这是我的异常(exception):

但是，这个问题似乎只发生在我的电脑上，项目在我同事的电脑上进行得很顺利。这是我的 xml 文件:

<bean id="subjectCcyDao" class="com.infohold.bdrp.sys.dao.impl.SubjectCcyDaoImpl" >
    <constructor-arg value="com.infohold.bdrp.sys.model.SubjectCcy" />
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="subjectCcyManager" class="com.infohold.bdrp.sys.service.impl.SubjectCcyManagerImpl">
    <constructor-arg ref="subjectCcyDao" />
    <property name="subjectCcyDao" ref="subjectCcyDao" />
</bean>
<bean id="subjecCcyAction" class="com.infohold.bdrp.sys.action.SubjecCcyAction" parent="baseAction" scope="prototype">
    <property name="subjectCcyManager" ref="subjectCcyManager" />
    <property name="subjectDictManager" ref="subjectDictManager" />
</bean>

当我注释掉这个 xml 时，错误错过了。但我仍然找不到错误。 这个问题我google了一整天都找不到答案，谁能告诉我原因吗？谢谢。

编辑(2016/02/22):我确认在我的案例中这个问题已经通过迁移到 Spring 3.1.4 得到解决

---

我没有干净的解决方案，但有一些线索。

当我从 Java 1.7.0_75 切换到 Java 1.8.0_74 时，这个错误开始发生。我怀疑这与 Java 8 中反射实现的变化有关。

我们使用 Spring 3.1.3，我相信这个问题可能会根据这个在 3.1.4 中得到修复 - https://jira.spring.io/browse/SPR-9330

当我探索堆栈跟踪时，我注意到当 Spring Security 试图在您的代码中查找 @Secured 注释时会发生此错误。这可以通过将 secured-annotations 设置为 disabled 来禁用(如果你真的不需要它)，例如:

<security:global-method-security secured-annotations="disabled" />
