当前使用版本

mybatis-plus-3.3.1、spring-boot-2.2.2.RELEASE

该问题是如何引起的？

将spring-boot项目瘦身打包（依赖不变的jar包放到lib文件夹下）后，自己写的mapper xml文件只要有\<sql>标签 类似这种： \<sql id="columns"> id, name \<\/sql> 启动jar将会报错

重现步骤(如果有就写完整)

如果spring-boot没有瘦身打包 不会出现这种情况 已经确认id都是唯一的 如果我全部去掉xml中的\<sql>标签 启动不会报错

最后的错误日志 Caused by: java.lang.IllegalArgumentException: XML fragments parsed from previous mappers already contains value for com.dage.ha.srab.portal.dao.DeviceDao.columns at org.apache.ibatis.session.Configuration$StrictMap.put(Configuration.java:947) at org.apache.ibatis.session.Configuration$StrictMap.put(Configuration.java:903) at org.apache.ibatis.builder.xml.XMLMapperBuilder.sqlElement(XMLMapperBuilder.java:351) at org.apache.ibatis.builder.xml.XMLMapperBuilder.sqlElement(XMLMapperBuilder.java:342) at org.apache.ibatis.builder.xml.XMLMapperBuilder.configurationElement(XMLMapperBuilder.java:119) ... 57 common frames omitted

我debug的时候发现确实是重复了 但是不知道是什么原因 瘦身打包在cmd下面执行java -jar就会报错

我已经自己解决这个问题了 是我扫描xml文件导致的问题
