Right way of using Governator's @configuration annotation

RightWayToUseConfiguration.java

public class MyClass {
  @Configuration("path.prefix")
  private String pathPrefix;
  
  private String fileName;
  
  public MyClass(String fileName) {
    this.fileName = fileName; //here we simply store it
  }
  
  @PostConstruct
  void initialize() {
    fileName = pathPrefix + fileName; //and here we use the configuration setting and create the full path
  }
  //... rest of the work goes here
}
