  3. spring.factories in src/main/resources/META-INF; If the file exists, remove org.springframework.boot.autoconfigure.EnableAutoConfiguration from the file and copy all the configuration into org.springframework.boot.autoconfigure.AutoConfiguration.imports in src/main/resources/META-INF/spring see: https://github.com/folio-org/folio-spring-base/blob/feature/FOLSPRINGB-81/src/main/resources/META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports

  5. Dockerfile
    1. Change: FROM folioci/alpine-jre-openjdk17:latest
    2. Add (for details see README):

USER folio
  6. Application.yaml
    1. Add: spring.cloud.openfeign.okhttp.enabled = true if a project uses FeignClient
    2. Change: spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect
  7. If a module uses PostgreSQL ENUMs
    1. pom.xml: add hypersistence-utils-hibernate-60 dependency see: https://github.com/folio-org/mod-password-validator/blob/feature/MODPWD-110/pom.xml#L88
    2. In entity classes replace @Type annotation with @Enumerated(EnumType.STRING) @Type(PostgreSQLEnumType.class) see: https://github.com/folio-org/mod-password-validator/blob/feature/MODPWD-110/src/main/java/org/folio/pv/domain/entity/PasswordValidationRule.java#L32

  9. According to Spring Doc in Spring Boot 3.0.0 (from Spring Framework 5.8) WebSecurityConfigurerAdapter was deprecated and SecurityFilterChain was introduced.
    So WebSecurityConfigureAdapter must be removed and authorizeRequests() deprecated method changed to authorizeHttpRequests()
