Spring Framework: Spring Expression Language (SpEL)

Spring Expression Language (SpEL) was introduced in Spring 3.0 in 2009. It is a powerful but often underutilized feature of Spring. This course will teach you how to harness its power in dynamic bean wiring/ dependency injecting. It is possible by writing String expressions which are evaluated at run-time. You'll first learn how to use SpEL to query an object and manipulate it. Next, you will learn how to use an object graph in runtime, which allows you to dynamically insert values or objects into other beans. You'll also learn how SpEL can be used to conditionally select the bean or value that you want to depend on based on an application's conditions. After completing this course, SpEL can be applied to any application.
