public class StringToDataConverter implements Converter<String, Date> {
  @Override
    public Date convert(String s) {
      SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
      Date parse = null;
      try {
          parse = sdf.parse(s);
      } catch (ParseException e) {
          e.printStackTrace();
      }
      return parse;

  }
}

2、在spring中进行配置
   <!--配置转换器,在开启注解中引用才能生效-->
    <bean id="conversionServiceFactoryBean" class="org.springframework.context.support.ConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <bean class="cn.itcast.utils.StringToDataConverter"></bean>
            </set>
        </property>
    </bean>

    <!-- 开启SpringMVC框架注解的支持 -->
    <mvc:annotation-driven conversion-service="conversionServiceFactoryBean"/>
