Interceptor has thrown exception, unwinding now

当出现 ClassCastException "Interceptor has thrown exception, unwinding now",并且出现在访问类implements CallbackHandler接口的时候,主要问题是
WSS4J的配置写错导致的,通常是passwordCallbackRef这个KEY 写错导致!

<bean id="wss4jInInterceptor" class="org.apache.cxf.ws.security.wss4j.WSS4JInInterceptor">
<constructor-arg>
<map>
<entry key="action" value="UsernameToken" />
<entry key="passwordType" value="PasswordText" />
<entry key="passwordCallbackRef">
<ref bean="wsServerAuthHandler" />
</entry>
</map>
</constructor-arg>
</bean>


client端的配置:
<bean id="helloClient" class="com.cigna.cmc.test.service.HelloWorld"
factory-bean="helloClientFactory" factory-method="create" />
<bean id="helloClientFactory" class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean">
<property name="serviceClass" value="com.cigna.cmc.test.service.HelloWorld" />
<property name="address"
value="http://localhost:8080/CFXDemoServer/HelloWorld" />
<property name="outInterceptors">
<list>
<bean class="org.apache.cxf.binding.soap.saaj.SAAJOutInterceptor" />
<ref bean="wss4jOutConfiguration" />
</list>
</property>
</bean>
<bean id="wss4jOutConfiguration" class="org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor">
<property name="properties">
<map>
<entry key="action" value="UsernameToken" />
<entry key="user" value="fisher" />
<entry key="passwordType" value="PasswordText" />
<entry>
<key>
<value>passwordCallbackRef</value>
</key>
<ref bean="passwordCallback" />
</entry>
</map>
