xml文件格式不对，下面红色的要一直，你的应该是没有DOCTYPE ,并且根节点写成了additionalHeaders

<!DOCTYPE xxx
<xxx>
</xxx>

[sound02]

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.sz.nexus.repository.dao.mapper.FileMetaMapper" >


我是用mybatis逆向工程生成的代码

有关掉的，

有没有可能是jar包冲突？

Caused by: org.xml.sax.SAXParseException: Document root element "additionalHeaders", must match DOCTYPE root "null".

按这个提示就是xml解析错误
把全日志贴出来，看看能不能查到是哪个xml的问题？

关键是，我用同样的多模块建立另外一个就能跑

就是包冲突
