Then, in the second line, we tell the context where to load its bean definitions from. Once more, setConfigLocations would be the programmatic analogous of your contextConfigLocation parameter in World-wide-web.xml

Spring allows you to Make multilevel application context hierarchies, And so the required bean are going to be fetched from your guardian context if it is not existing in the current application context.
