<mvc:annotation-driven/>都做了那些事情

mvc:annotation-driven是一种简写的配置方式，那么mvc:annotation-driven到底做了哪些工作呢？如何替换掉mvc:annotation-driven呢？

<mvc:annotation- driven/>在初始化的时候会自动创建两个对 象，org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter 和 org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter， 我们如果想不使用<mvc:annotation-driven/>这种简写方式，将其替换掉的话，就必须自己手动去配置这两个bean对 象。下面是这两个对象的配置方法，和详细的注视说明。

    <bean id="conversionService"

            </list>
        </property>
    </bean>

</beans>

这样，我们就可以就成功的替换掉<mvc:annotation-driven />了。
