Java uniVocity-按位置转换为列表

希望这能有所帮助。您正试图通过自定义转换将多个列（

@Parsed（field=“email1”）

希望这能有所帮助。我用另一种方式实现了我想要的，不是我想要的，但它奏效了。我使用MultiBeanProcessor并创建了虚拟类（我的老板不会喜欢）来表示我的csv位置 我的真实csv有如下标题： email1，email2，email3，dddcel1，dddcel2，dddcel3，dddcel4，dddtel1，dddtel2，dddtel3，名字，文件，v_atu，ofe_cc，ignore1，银行，机构，ignore2，发票号码，联系电话，地址，邻居，邮编，城市，州 和多处理器
