SpringMVC 传日期参数到后台的实例讲解

@InitBinder
public void initBinder(HttpServletRequest request,ServletRequestDataBinder binder)throws Exception { 
  DateFormat fmt = new SimpleDateFormat("yyyy-MM-dd"); 
  CustomDateEditor dateEditor = new CustomDateEditor(fmt, true); 
  binder.registerCustomEditor(Date.class, dateEditor); 
}

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

<!-- 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"/>
