如何使用JAXB在Java中将CSV转换为XML

本文介绍了如何使用JAXB在Java中将CSV转换为XML的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正尝试使用apache骆驼使用CSV文件，并将每一行转换为XML，然后将每个xml发布为可安慰主题. XML格式很复杂，我不确定如何在Java中创建如此复杂的XML. CSV包含员工有效负载字段. XML的其他部分(包括标头，auditRecords和ancillaryData)都是硬编码/静态数据(时间戳可以是当前日期).

I am trying to consume a CSV file using apache camel and convert each row to XML and publish each xml to solace topic. XML format is complex and I am not sure how to create such a complex XML in Java. CSV contains employee payload fields. Other part of XML including header, auditRecords and ancillaryData are hardcoded/static data(timestamp can be current date).

如何使用JAXB在Java中将CSV转换为XML?

How to convert CSV to XML in Java using JAXB?

我设法根据上述XML模式创建了XML.我跳过了ancillaryData和auditRecord元素，因为它不是必需的.让我知道这是否是形成XML的正确方法.

I managed to create the XML based on the above XML schema.I skipped ancillaryData and auditRecord elements as it was not mandatory.Let me know if this is the correct way of forming the XML.
