Basic annotations in spring boot code#

Spring supports JSR-250 based annotations which include and annotations. Let us look at a few important annotations to understand how they work − Sr.No.Īnnotation & annotation applies to bean property setter annotation can apply to bean property setter methods, non-setter methods, constructor and annotation along with can be used to remove the confusion by specifiying which exact bean will be wired.

Basic annotations in spring boot code#

Once is configured, you can start annotating your code to indicate that Spring should automatically wire values into properties, methods, and constructors. You can annotate any field with Getter and/or Setter, to let lombok generate the default getter/setter automatically. So consider the following configuration file in case you want to use any annotation in your Spring application. the names of packages to be selected when running a test suite. So, before we can use annotation-based wiring, we will need to enable it in our Spring configuration file. Get started with Spring 5 and Spring Boot 2, through the Learn Spring course: > CHECK OUT THE COURSE. Thus, the latter configuration will override the former for properties wired through both approaches.Īnnotation wiring is not turned on in the Spring container by default. So instead of using XML to describe a bean wiring, you can move the bean configuration into the component class itself by using annotations on the relevant class, method, or field declaration.Īnnotation injection is performed before XML injection.

Starting from Spring 2.5 it became possible to configure the dependency injection using annotations.
