Issue
I have a problem trying to upgrade a spring project from 4.3.2 to the latest ones. The project uses: 4.1.1.Release security and 4.3.2 Spring framework. I am trying to upgrade them to 5.3.13Release and 5.2.19.Release for spring only.
App also uses websockets:
Correct the classpath of your application so that it contains a single, compatible version of org.springframework.web.socket.server.standard.ServletServerContainerFactoryBean

Solution
First, you cannot upgrade Spring for Spring Boot as that is tied to a specific Spring major version. To upgrade Spring you would need to upgrade to a newer Spring Boot version.
Secondly, your dependencies are a mess. A lot of exclusions that aren't needed and additional dependencies that aren't needed either.

</dependency>
This is for the Spring (Boot) dependencies. Remove the spring.version and spring-security.version unless you really want to override it (which can be done within the same major version!) but you are probably better of using a new Spring Boot version (update the version of the parent).
There are probably a lot more dependencies (the spring-boot-starter-data-jpa already pulls in hibernate, so you can probably remove that explicit one as well).
