自定义转换器:日期转换器

A)第一种方式:

  <!-- 开启注解方式: -->

   <mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>

 <!-- 自定义转换器 -->

    <bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">

         <property name="converters">

         <list>

             <bean class="cn.hd.comverter.DateConverter"></bean>

         </list>

         </property>

    </bean>  

2

public class DateConverter implements Converter<String, Date> {

@Override

public Date convert(String str) {

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");

try {

return sdf.parse(str);

} catch (ParseException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

return null;

}

   

  }

 B)第二种方式:

    @InitBinder

public void initBinder(ServletRequestDataBinder binder) {

binder.registerCustomEditor(Date.class, new CustomDateEditor(

new SimpleDateFormat("yyyy-MM-dd"), true));

}


/**
* @InitBinder会首先执行,将本类中所有属性是Date类型的,转换成自定义格式
* @param binder
*/
@InitBinder
public void initBinder(WebDataBinder binder){
SimpleDateFormat sd = new SimpleDateFormat("yyyy-MM-dd");
sd.setLenient(false);
binder.registerCustomEditor(Date.class, new CustomDateEditor(sd, false));

}
