spring 时间装配器 前后台date类型传值 date多重数据转换

亲测有效

1创建日期格式话工具DateEditor

import java.beans.PropertyEditorSupport;

import java.text.ParseException;

import java.util.Date;

 

/**

 * 日期格式话工具

 * SPRINGMVC日期字符换转换Date

 * @author ALLEN

 */

publicclassDateEditorextends PropertyEditorSupport {

   

   @Override

   publicvoidsetAsText(Stringtext)throwsIllegalArgumentException {

        Date date = null;

        try {

            date=DateUtil.parseDate(text);

        } catch (ParseExceptione) {

            e.printStackTrace();

        }

       

        setValue(date);

   }

}

2创建日期装配器

import java.util.Date;

 

import javax.servlet.http.HttpServletRequest;

 

import org.springframework.web.bind.ServletRequestDataBinder;

import org.springframework.web.bind.annotation.InitBinder;

/**

 *  日期装配器

 * @authorlxy

 * @date 2017年3月23日下午2:15:43

 */

publicclassDateBinderUtil {

   /**

     * 初始化日期格式

     *

     * @param request

     * @param binder

     * @throws Exception

     */

   @InitBinder

   protectedvoidinitBinder(HttpServletRequestrequest, ServletRequestDataBinderbinder) throwsException {

        binder.registerCustomEditor(Date.class,new DateEditor());

   }

}

3配置

 

   <beanclass="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">

        <propertyname="messageConverters">

            <list>

                <refbean="stringHttpMessageConverter"/>

            </list>

        </property>

   </bean>

   <beanid="stringHttpMessageConverter"class="org.springframework.http.converter.StringHttpMessageConverter">

        <propertyname="supportedMediaTypes">

            <list>

                <value>text/html;charset=utf-8</value>

            </list>

        </property>

</bean>

 

4附录DateUtil

// 从字符串中分析日期

   publicstatic DateparseDate(String dateStr)throws ParseException {

      Datedate=null;

      String[]dateArray=dateStr.split("\\D+");// +防止多个非数字字符在一起时导致解析错误

      intdateLen =dateArray.length;

      intdateStrLen =dateStr.length();

      if (dateLen > 0) {

        if (dateLen == 1 &&dateStrLen > 4) {

           if (dateStrLen =="yyyyMMddHHmmss".length()){

              //如果字符串长度为14位并且不包含其他非数字字符，则按照（yyyyMMddHHmmss）格式解析

              date =parseDate(dateStr,"yyyyMMddHHmmss");

           }elseif(dateStrLen=="yyyyMMddHHmm".length()) {

              date =parseDate(dateStr,"yyyyMMddHHmm");

           }elseif(dateStrLen=="yyyyMMddHH".length()) {

              date =parseDate(dateStr,"yyyyMMddHH");

           }elseif(dateStrLen=="yyyyMMdd".length()) {

              date =parseDate(dateStr,"yyyyMMdd");

           }elseif(dateStrLen=="yyyyMM".length()){

              date =parseDate(dateStr,"yyyyMM");

           }

        }else{

           StringfDateStr=dateArray[0];

           for (inti = 1; i < dateLen; i++) {

              //左补齐是防止十位数省略的情况

              fDateStr +=leftPad(dateArray[i],"0", 2);

           }

 

           if (dateStr.trim().matches("^\\d{1,2}:\\d{1,2}(:\\d{1,2})?$")) {

              //补充年月日3个字段

              dateLen += 3;

              fDateStr =formatDate(new Date(),"yyyyMMdd")+ fDateStr;

           }

 

           date =parseDate(fDateStr,"yyyyMMddHHmmss".substring(0,(dateLen- 1) * 2 + 4));

        }

      }

 

      returndate;

   }
