处理Java应用程序中的Spring Bean故障

Question

我对Spring Framework完全陌生。我正在开发一个针对传入请求进行两种身份验证的应用程序。在bean.xml中，我有两种类型的身份验证处理程序。我的要求是，如果一个身份验证处理程序失败，它应该不会中断，而应该继续进行下一个身份验证处理程序。我该如何实现呢？我们可以在bean.xml中指定吗，如果处理程序抛出异常，spring执行应该不会失败并且应该继续执行下一个身份验证。

Since you are unable to post your bean.xml file , I am assuming you have declared your authentication managers like:

<security:authentication-manager>
  <security:authentication-provider ref="AAuthProvider" />
  <security:authentication-provider ref="BAuthProvider" />
</security:authentication-manager>

By default, spring is designed to evaluate the handlers in a linear fashion. Meaning, they will be evaluated in order. If one fails, it automatically goes to the next one.
