配置文件里面先注册自定义转换器：
第一种配置：
<mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>
<!-- 自定义日期参数绑定 -->
<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<!-- 转换器 -->
<property name="converters">
<list>
<bean class="com.web.util.DateConverter"></bean>
</list>
</property>
</bean>第二种配置：
<!--注解适配器 -->
<bean
class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="webBindingInitializer" ref="customBinder"></property>
</bean>
<!-- 自定义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">
<!-- 转换器 -->
<property name="converters">
<list>
<bean class="com.web.util.DateConverter"/>
</list>
</property>
</bean>自定义转换器Converter:
