SpringMVC类型转换器

SpringMVC自定义类型转换器，String转Date

首先创建自定义转换器类，实现Converter接口

public class Convert implements Converter<String,Date> {

    public Date convert(String s) {
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
        System.out.println("aaaaaaaaaa");
        try {
            return formatter.parse(s);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return null;
    }
}

然后在配置文件中加入配置

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

   <!-- 自定义参数绑定 -->

   <bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
      <property name="converters">
         <set>
            <bean class="cn.lhl.converter.Convert"></bean>
         </set>
      </property>
   </bean>
