bug宝典JAVA篇 BeanUtils.copyProperties 日期问题

来源：互联网发布：2016年网络流行词汇编辑：程序博客网时间：2024/06/05 16:05

执行BeanUtils.copyProperties(dest, orig);的时候出现下面的错误，我的代码如下,主要目的是复制对象，但是又不想一个个set,下面的BeanUtilsExtends是照着copyproperties 谁赋值给谁抄的，实际运用却出现下面的问题

@Transactional(readOnly = false)    private boolean createNewRecord(FontalMaintainLog record, Date nextOptDate){        FontalMaintainLog newRecord = new FontalMaintainLog();        BeanUtilsExtends.copyProperties(newRecord, record);        newRecord.setId(StringUtil.getUuidString());        newRecord.setOptDate(nextOptDate);        return insertSelective(newRecord);    }

debug发现，红色方框内容有问题，本来arg1就是日期类型，转字符串自然就报错了。

稍作调整如下：
