Unfortunately that won't work since we don't have any MyBatis integration in Quarkus

[newDevnew]

Thank you for your response.

Too bad, and suppose I use dependence :

    <dependency>
      <groupId>io.quarkiverse.mybatis</groupId>
      <artifactId>quarkus-mybatis</artifactId>
      <version>0.0.11</version>
    </dependency>

in the spring project, I will have the same problem ?

[geoand]

I don't really know, I have never used that extension
