Question

我尝试了一些在bean之间传输数据的方法。最快的方法是getset bean。第二快的方法是org.springframework.cglib.beans.BeanCopier。有没有比BeanCopier更快的方法？

    LOGGER.info("getset start trans data");
    commentList.stream().map(
            comment -> {
                CommentVO commentVO = new CommentVO();
                commentVO.setId(comment.getId());
                commentVO.setContent(comment.getContent());
                return commentVO;
            }
    ).collect(Collectors.toList());
    LOGGER.info("getset trans data compelete");

    LOGGER.info("Spring.BeanUtils start trans data");
    commentList.stream().map(
            comment -> {
                CommentVO commentVO = new CommentVO();
                BeanUtils.copyProperties(comment, commentVO);
                return commentVO;
            }
    ).collect(Collectors.toList());
    LOGGER.info("Spring.BeanUtils trans data compelete");

    LOGGER.info("BeanCopier start trans data");
    commentList.stream().map(
            comment -> {
                CommentVO commentVO = new CommentVO();
                BeanCopier beanCopier = BeanCopier.create(Comment.class, CommentVO.class, false);
                beanCopier.copy(comment, commentVO, null);

                return commentVO;
            }
    ).collect(Collectors.toList());
    LOGGER.info("BeanCopier trans data compelete");

    LOGGER.info("FASTJSON start trans data");
    commentList.stream().map(
            comment -> JSON.parseObject(JSON.toJSONString(comment), CommentVO.class)
    ).collect(Collectors.toList());
    LOGGER.info("FASTJSON trans data compelete");

结果：

14:21:09.343 [main] INFO com.southcn.nfplus.cmt.web.Main - getset start trans data
14:21:09.360 [main] INFO com.southcn.nfplus.cmt.web.Main - getset trans data compelete
14:21:09.360 [main] INFO com.southcn.nfplus.cmt.web.Main - Spring.BeanUtils start trans data
14:21:09.657 [main] INFO com.southcn.nfplus.cmt.web.Main - Spring.BeanUtils trans data compelete
14:21:09.657 [main] INFO com.southcn.nfplus.cmt.web.Main - BeanCopier start trans data
14:21:09.805 [main] INFO com.southcn.nfplus.cmt.web.Main - BeanCopier trans data compelete
14:21:09.805 [main] INFO com.southcn.nfplus.cmt.web.Main - FASTJSON start trans data
14:21:10.396 [main] INFO com.southcn.nfplus.cmt.web.Main - FASTJSON trans data compelete

在没有getset的情况下将bean转换为另一个bean的最快方法是什么？
