 builder.factory(ObjectFactory.class, Scope.SINGLETON);
        builder.factory(ActionFactory.class, DefaultActionFactory.class, Scope.SINGLETON);
        builder.factory(ResultFactory.class, DefaultResultFactory.class, Scope.SINGLETON);
        builder.factory(InterceptorFactory.class, DefaultInterceptorFactory.class, Scope.SINGLETON);
        builder.factory(com.opensymphony.xwork2.factory.ValidatorFactory.class, com.opensymphony.xwork2.factory.DefaultValidatorFactory.class, Scope.SINGLETON);
        builder.factory(ConverterFactory.class, DefaultConverterFactory.class, Scope.SINGLETON);


        builder.factory(FileManager.class, "system", DefaultFileManager.class, Scope.SINGLETON);
        if (!fmFactoryRegistered) {
            builder.factory(FileManagerFactory.class, DefaultFileManagerFactory.class, Scope.SINGLETON);
        }
        builder.factory(ReflectionProvider.class, OgnlReflectionProvider.class, Scope.SINGLETON);
        builder.factory(ValueStackFactory.class, OgnlValueStackFactory.class, Scope.SINGLETON);

        builder.factory(XWorkConverter.class, Scope.SINGLETON);
        builder.factory(ConversionPropertiesProcessor.class, DefaultConversionPropertiesProcessor.class, Scope.SINGLETON);
        builder.factory(ConversionFileProcessor.class, DefaultConversionFileProcessor.class, Scope.SINGLETON);
        builder.factory(ConversionAnnotationProcessor.class, DefaultConversionAnnotationProcessor.class, Scope.SINGLETON);
        builder.factory(TypeConverterCreator.class, DefaultTypeConverterCreator.class, Scope.SINGLETON);
        builder.factory(TypeConverterHolder.class, DefaultTypeConverterHolder.class, Scope.SINGLETON);

        builder.factory(XWorkBasicConverter.class, Scope.SINGLETON);
        builder.factory(TypeConverter.class, XWorkConstants.COLLECTION_CONVERTER,  CollectionConverter.class, Scope.SINGLETON);
        builder.factory(TypeConverter.class, XWorkConstants.ARRAY_CONVERTER, ArrayConverter.class, Scope.SINGLETON);
        builder.factory(TypeConverter.class, XWorkConstants.DATE_CONVERTER, DateConverter.class, Scope.SINGLETON);
        builder.factory(TypeConverter.class, XWorkConstants.NUMBER_CONVERTER,  NumberConverter.class, Scope.SINGLETON);
        builder.factory(TypeConverter.class, XWorkConstants.STRING_CONVERTER, StringConverter.class, Scope.SINGLETON);
        builder.factory(TextProvider.class, "system", DefaultTextProvider.class, Scope.SINGLETON);
        builder.factory(ObjectTypeDeterminer.class, DefaultObjectTypeDeterminer.class, Scope.SINGLETON);
        builder.factory(PropertyAccessor.class, CompoundRoot.class.getName(), CompoundRootAccessor.class, Scope.SINGLETON);
        builder.factory(OgnlUtil.class, Scope.SINGLETON);
        builder.constant(XWorkConstants.DEV_MODE, "false");
        builder.constant(XWorkConstants.LOG_MISSING_PROPERTIES, "false");
        builder.constant(XWorkConstants.ENABLE_OGNL_EVAL_EXPRESSION, "false");
        builder.constant(XWorkConstants.ENABLE_OGNL_EXPRESSION_CACHE, "true");
        builder.constant(XWorkConstants.RELOAD_XML_CONFIGURATION, "false");
        return builder.create(true);

  

2.加载xml中定义的Bean:

  默认XML为：struts-default.xml,struts-plugin.xml,struts.xml

 可自定义加载XML：

Struts Filter的初始化参数可配置：

名：config

值：xml文件名，多个文件中间用逗号分隔

 

struts-default.xml:
