Spring自定义转换器<11>

1. 定义转换器

package com.company.combine.conveter;


import org.springframework.core.convert.converter.Converter;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

/**

 */
public class DateConverter implements Converter<String,Date> {

    @Override
    public Date convert(String s) {
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");
        Date date = null;
        try {
            date = sdf.parse(s);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        return date;
    }
}

2. Spring中配置

  <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <bean id="dateConverter" class="com.company.combine.conveter.DateConverter" />
            </set>
        </property>
    </bean>

3.测试

  @RequestMapping(value = "/updateitem.action")
 public void updateItem(Date createtime) {
        System.out.println("createtime:" + createtime.toString());
        }

4.输入

2017-08-18 22-10-10

5.结果

createtime:Fri Aug 18 22:10:10 CST 2017
