配置檔案裡面先注冊自定義轉換器：

第一種配置：

<mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>
	
<!-- 自定義日期參數綁定 -->
	<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
	      <!-- 轉換器 -->
	        <property name="converters">
	           <list>
	              <bean class="com.web.util.DateConverter"></bean>
	           </list>
	        </property>
	</bean>           

第二種配置：

<!--注解擴充卡 -->
	<bean
		class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
		 <property name="webBindingInitializer" ref="customBinder"></property> 
	</bean>
	
	<!-- 自定義webBinder -->
	<bean id="customBinder"
		class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
		<property name="conversionService" ref="conversionService" />
	</bean>
	<!-- conversionService -->
	<bean id="conversionService"
		class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
		<!-- 轉換器 -->
		<property name="converters">
			<list>
				<bean class="com.web.util.DateConverter"/>
			</list>
		</property>
	</bean>
