title: I want to set a HashMap with SpringBoot and get the values next in other class
body: <p>I'm working with Spring Boot, and I need to load a HashMap with some values from Class A. </p>
  
  <p>Then, I need to get the values from this HashMap in Class B, Class C, etc.</p>
  
  <p>So I need a HashMap that load at first my values, and then, use this Map throughout the other classes.</p>
  
  <p>Thanks.</p>
