配置里先寫配置
<!-- conversion-service 指定需要用的轉(zhuǎn)換器 -->
       <mvc:annotation-driven conversion-service="convertorService"></mvc:annotation-driven>
    <!-- 設(shè)置自定義的轉(zhuǎn)換器 -->
         <bean id="convertorService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
            <property name="converters">
                <list>
                    <bean class="com.qianfeng.trans.CustomerDateConvert"></bean>
                    <bean class="com.qianfeng.trans.CustomerIntConvert"></bean>
                </list>
            </property>
         </bean>

這個(gè)寫類要跟上面class里定義的指向一樣
public class CustomerDateConvert implements Converter<String, Date>{

    @Override
    public Date convert(String info) {
        // TODO Auto-generated method stub
        if(info == null || info.isEmpty()){
            return null;
        }
        // 定義數(shù)組，保存支持的日期字符串的格式
        SimpleDateFormat[] sdfs = new SimpleDateFormat[]{
                new SimpleDateFormat("yyyy-MM-dd"),
                new SimpleDateFormat("yyyy/MM/dd"),
                new SimpleDateFormat("yyyyMMdd")
        };
        for (SimpleDateFormat sdf : sdfs) {
            
            // 受檢異常、非受檢異常
            try {
                return sdf.parse(info);
            } catch (ParseException e) {
                // TODO Auto-generated catch block
                //e.printStackTrace();
                continue;
            }
            
        }
        
        return null;
    }

}

只要是類型是date的都會(huì)自動(dòng)可以轉(zhuǎn)換
