Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true

How to fix it?

Solution

Happen when you using Spring Security with Spring Native. This is a know issue due to Spring Native compile ( https://github.com/spring-projects/spring-boot/issues/38910 ). Wait to Spring 3.2.2 or using snapshot for resolving problem.
