在寫一個mybatis測試demo時發現配置mybatis.xml報錯如下：
org.apache.ibatis.exceptions.PersistenceException:
### Error building SqlSession.

請根據上述報錯仔細查看：Cause: org.xml.sax.SAXParseException; lineNumber: 31; columnNumber: 17; 元素類型爲 "configuration" 的內容必須匹配 。主要是要配置文件中沒有按標籤順序：properties-->settings-->typeAliases-->typeHandlers-->objectFactory-->objectWrapperFactory-->reflectorFactory-->plugins-->environments-->databaseIdProvider-->mappers。所以在你的配置文件中按上述標籤順序修改即可解決。
