What you'll learn

Spring Expression Language (SpEL), introduced with Spring 3.0 back in 2009, is a powerful yet seemingly underutilized feature of Spring. In this course, you'll learn to harness it's power in dynamic bean wiring/ dependency injection which is made possible through writing String expressions that gets evaluated at run time. First, you'll discover how to leverage the power of SpEL to query and manipulate an object. Next, you'll see how to use an object graph at run time, making it possible to dynamically inject values or objects in to other beans. Finally, you'll explore the conditionalization ability of SpEL to pick the right bean or value to dependency inject based on the conditions in an application. When you're finished with this course, you'll be able to apply SpEL to any application.
