问题分析

根据日志信息，有以下问题需要解决：

  1. 找不到MyBatis的Mapper：日志中显示'No MyBatis mapper was found in '[com.scq]' package. Please check your configuration.'，这可能是因为没有正确配置Mapper扫描路径。请检查配置文件中的Mapper扫描路径是否正确。

  2. 解析Mapper XML错误：日志中显示'Mapper's namespace cannot be empty'，这可能是因为Mapper XML文件中的namespace为空。请检查Mapper XML文件中的namespace是否正确配置。

  3. 解析Mapper XML错误：日志中显示'Failed to parse mapping resource'，这可能是因为Mapper XML文件的解析错误。请检查Mapper XML文件是否正确配置，特别是检查XML文件的格式、标签是否正确闭合等。

解决方法

  1. 检查Mapper扫描路径配置：

    • 在 Spring Boot 的配置文件（application.properties 或 application.yml）中，确保配置了正确的Mapper扫描路径，例如： 
      mybatis.mapper-locations=classpath*:mapper/*.xml

  2. 检查Mapper XML文件的namespace配置：

    • 打开 DictionaryTypeMapper.xml 文件，确保 <mapper> 标签的 namespace 属性已正确设置，例如： 
      <mapper namespace="com.scq.mapper.DictionaryTypeMapper"> 
    ...
</mapper>
      • namespace 属性的值应与Mapper接口的完全限定名一致。

  3. 检查Mapper XML文件格式和标签闭合：

    • 仔细检查 DictionaryTypeMapper.xml 文件的格式，确保 XML 文件的格式正确、标签正确闭合，没有语法错误。
    • 可以使用 XML 编辑器或在线验证工具来检查 XML 文件的格式。

总结

通过检查以上三个方面的问题，并进行相应的修改，即可解决Spring Boot启动失败：MyBatis Mapper解析错误的问题。
