resteasy-spring-boot | RESTEasy Spring Boot Starter | Microservice library

Your pom contains way to much, it contains conflicting jars and it is even mixing jars from different versions of frameworks (Spring, Spring Boot, Axis, etc.) all that is trouble waiting to happen.

All of this comes from the simple fact you are trying to update to much at a time. When upgrading take small steps, so that you know what breaks what, as explained here.

That being said cleanup your pom.

1. Remove commons-logging
2. Remove slf4j dependencies
3. Remove spring-jdbc
4. Remove spring-orm use spring-data-starter-jpa instead
5. Fix versions for Axis
6. Fix versions of Spring Boot dependencies
7. Remove aopalliance
8. Remove cglib
9. Remove jackson dependencies as those aren't supported by Spring (and are already included in spring-boot-starter-web.
10. Use spring-boot-starter-mail instead of javax.mail dependencies
11. log4j isn't supported and adding a dependency on a 1.3.8 spring boot version in a 2.2.4 app is trouble. Either use log4j2 or the default logback.
12. Use the default HikariCP connection pool, excluding tomcat doesn't help as it isn't included, just stick with the defaults.
13. There are a ton of XML marshallers, JAXB, XMLBEans, Jibx and all are included in your app, which is it you are using?
14. spring-boot-starter-aop already includes the AspectJ dependencies
15. spring-security-rsa points to an old Spring Security version, you might want to upgrade to 1.0.9
16. Use the MyBatis Spring Boot starter instead of seperate dependencies

Here is a, partially, cleaned up pom.xml. I haven't fixed versions or removed xml marshallers. I did remove slf4j, log4j and the different spring-jdbc/spring-orm dependencies. As well as the jackson ones. I also grouped the Spring Boot dependencies together at the top.
