spring 版本：spring-framework-3.2.12.RELEASE

需要额外jar包：jackson-mapper-asl-1.9.7.jar和jackson-core-asl-1.9.7.jar

spring-servlet.xml配置

        <property name="supportedMediaTypes">

    <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
    <bean
        class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
        <property name="messageConverters">
            <list>

    </bean>
</beans>

其中 <mvc:annotation-driven />这行一定不可以缺少，否则也会返回失败
