<!-- 第一步: 创建自定义日期转换规则 -->
<bean id="dateConvert" class="xxx.xxx.DateConvert"/>

<!-- 第二步： 创建convertion-Service ，并注入dateConvert-->
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
 <property name="converters">
  <set>
   <ref bean="dateConvert"/>
  </set>
 </property>
</bean>

<!-- 第三步：注册处理器映射器/处理器适配器 ，添加conversion-service属性-->
<mvc:annotation-driven conversion-service="conversionService"/>
