在spring使用annotation时错误

在运行启动时有下面的错误

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalRequiredAnnotationProcessor': Initialization of bean failed; nested exception is org.springframework.beans.InvalidPropertyException: Invalid property 'order' of bean class [org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor]: No property 'order' found
Caused by: org.springframework.beans.InvalidPropertyException: Invalid property 'order' of bean class [org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor]: No property 'order' found

at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1105)

在spring 2.0.6包中的RequiredAnnotationBeanPostProcessor这个类没有order属性

这时把spring的包更新成2.5.6的就可以了，看代码，确实有order这个属性

private int order = Ordered.LOWEST_PRECEDENCE - 1;
