CodePudding user response：

Spring 5 is JakartaEE 9 or 10 , so you either need to use WildFly 27 or 26-preview.

CodePudding user response：

If we need to use spring 5, then we need to use Jakarta EE 8 Full & Web Distribution of wildlfy 26.1.2 not WildFly Preview EE 9.1 Distribution. I was using preview, hence above error.
