来自嵌套导入资源的 spring bean 引用

Question

我有一个 spring 配置文件 service.xml ，它导入 applicationContext.xml ，而我的 applicationContext.xml 导入 security.xml 。

现在在我的 service.xml 中定义了一个 bean

<bean id="mySecurityInterceptor" class="org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor">
<property name="validationActions" value="UsernameToken" />
<property name="securementActions" value="UsernameToken" />
<property name="validationCallbackHandler" ref="myPasswordCallbackHandler" />

这个 myPasswordCallbackHandler bean 是在 security.xml 中定义的，但是在加载应用程序上下文时，我找不到 myPasswordCallbackHandler 的 bean 定义。

如何引用这个 myPasswordCallbackHandler bean ？

谢谢！

这是 stackTrace：

这是我的 myPasswordCallbackHandler def：

<beans:bean id="myPasswordCallbackHandler"
  class="org.springframework.ws.soap.security.wss4j.callback.SpringPlainTextPasswordValidationCallbackHandler">
<beans:property name="authenticationManager" ref="authenticationManager"/>

Answer 1

看起来您可能在某个地方有拼写错误，您的帖子中引用了两个 bean：mySecurityPasswordCallbackHandler 和 myPasswordCallbackHandler。确保您使用正确的名称。

Answer 2

不确定这是否有帮助，但您可以尝试显式依赖

<bean id="mySecurityInterceptor" class="org.springframework.ws.soap.security.wss4j.Wss4jSecurityInterceptor" depends-on="myPasswordCallbackHandler">
<property name="validationActions" value="UsernameToken" />
<property name="securementActions" value="UsernameToken" />
<property name="validationCallbackHandler" ref="myPasswordCallbackHandler" />

假设您有一个名为 myPasswordCallbackHandler 的 bean 并且所有导入语句都正确，我没有看到任何使用问题。
