struts2.5.5与spring3.4.4集成报错:Unable to load config class I18nInterceptor

遇到的问题：
Unable to load config class org.apache.struts2.interceptor.I18nInterceptor at interceptor

org.springframework.beans.factory.NoUniqueBeanDefinitionException: No qualifying bean of type [com.opensymphony.xwork2.LocaleProvider] is defined:

Unable to create a Configuration, because no Bean Validation provider could be found. Add a provider like Hibernate Validator (RI) to your classpath

问题原因：
这struts2的配置和spring4的action bean配置有关
struts2配置：

<constant name="struts.objectFactory.spring.autoWire" value="type" />

spring4的action bean配置配置

	<bean id="dicCBBAction" class="com.asiainfo.migration.struts2.action.cbb.DictionaryCBBAction" scope="prototype">

		<property name="dataService">

			<ref bean="tPubDictionaryService" />

		</property>

	</bean>

解决办法：
修改spring配置为：

	<bean id="dicCBBAction" class="com.asiainfo.migration.struts2.action.cbb.DictionaryCBBAction" autowire="no" autowire-candidate="false" scope="prototype">

		<property name="dataService">

			<ref bean="tPubDictionaryService" />

		</property>

	</bean>

上面加上了autowire="no" autowire-candidate="false" ，问题解决！

另外附struts2.5.5与spring4.3.3集成的注意细节：
如果使用了struts的动态方法调用

<constant name="struts.enable.DynamicMethodInvocation" value="true" />

对于struts2.5.5 package需要加上strict-method-invocation="false"

<package name="admin" namespace="/admin" extends="struts-default" strict-method-invocation="false">
