1.编写日期转换器

package com.ync365.common.spring;  import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.Date;import org.springframework.core.convert.converter.Converter;/**   * ClassName:DateConvert 日期转换器 <br/>  * Date:     2017年3月1日 下午4:26:33 <br/>   * @author   ztd   * @version     * @see         */public class DateConvert implements Converter<String, Date> {    private final SimpleDateFormat yyyyMMdd = new SimpleDateFormat("yyyy-MM-dd");    private final SimpleDateFormat yyyyMMddHHmmss = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");    private final int leng_yyyyMMdd = 10;    private final int leng_yyyyMMddHHmmss = 19;    @Override    public Date convert(String source) {        if(source.length() == leng_yyyyMMdd) {            try {                return yyyyMMdd.parse(source);            } catch (ParseException e) {                e.printStackTrace();              }        } else if(source.length() == leng_yyyyMMddHHmmss) {            try {                return yyyyMMddHHmmss.parse(source);            } catch (ParseException e) {                e.printStackTrace();              }        }        return null;    }}

2.配置到 spring-mvc.xml 配置文件中

<bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">            <property name="converters">                <list>                    <bean class="com.ync365.common.spring.DateConvert" />                </list>            </property>        </bean>

3.将配置添加到 mvc:annotation-driven 标签中

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