'Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener Error

I am trying to implement Spring Security within my REST API. My project was working perfectly until I started to implement Spring. I believe the issue has something to do with Spring Boot in some way or another.

Stacktrace:

Solution 1:^[1]

This error is a result of having some non-compatible versions of Spring libraries in your classpath. The spring-boot dependencies should normally take care of pulling in all their required dependencies, but if for any reason you must declare all your dependencies manually, then always make sure that you use the same Spring versions. In your pom currently you have multiple 4.1.3 and 4.2.5 dependencies.

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>4.2.5.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-core</artifactId>
    <version>4.1.3.RELEASE</version>
</dependency>
