Dozer 时间转换问题

Dozer 时间转换问题

使用Dozer的原因 是因为po、dto转为vo 的互转
不用的话 就要一个个set，get
如果每个实体都要配置一个xml 的话开发效率很低

• 实例 场景 （就是这么方便）

  @ResponseBody
    public RtnResult findPageOrderByWhere(@RequestBody FinancingOrderVo vo) {
        FinancingOrder forder=DozerUtils.map(vo, FinancingOrder.class);
    ......................... 

• 测试

testEntityVo vo = new testEntityVo();

        vo.setTdDate("2019-05-25 09:23:45:00");
        vo.setBytes("1");
        vo.setBmoney("100.11");
        vo.setMun("100");
        vo.setCreaterId("1000");
        vo.setName("dozer");
        // vo 转换成po
        testEntity o = DozerUtils.map(vo, testEntity.class);//转换
        testEntityVo os = DozerUtils.map(o, testEntityVo.class);
        System.out.println(o.toJson());
        System.out.println(os.toJson());

• 打印日志

{"bmoney":100.11,"bytes":1,"createrId":1000,"mun":100,"name":"dozer","tdDate":1558747425000}

{"bmoney":"100.11","bytes":"1","createrId":"1000","mun":"100","name":"dozer","tdDate":"2019-05-25 09:23:45:00"}

直接贴代码吧

dozer-date.xml

StringToDateConverter.java 这个路径要配置在dozer-dadte.xml 中

package com.gls.test;

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

import org.dozer.DozerConverter;

public class StringToDateConverter extends DozerConverter<String, Date> {

    public StringToDateConverter() {
        super(String.class, Date.class);
    }

    @Override
    public String convertFrom(Date source, String destination) {
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SS");
        destination = formatter.format(source);
        return destination;
    }

    @Override
    public Date convertTo(String source, Date destination) {
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss:SS");
        ParsePosition pos = new ParsePosition(0);
        destination = formatter.parse(source, pos);
        return destination;
    }

}
