在其他对象属性类型一样情况下，只需要在springmvc.xml中添加配置：

<!--全局类型转型器-->
    <bean id="converter" class="com.ujiuye.common.DateTimeConverter"></bean>
    <bean id="formattingConversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <ref bean="converter"></ref>
            </set>
        </property>
    </bean>
    <mvc:annotation-driven conversion-service="formattingConversionService"/>

<mvc:annotation-driven/>
