First, let’s define a spring component with an empty dowork method: The reason for this error is that you have defined a member variable of your repository class in the spring controller class but have not @autowired it. This worked fine in spring boot 2.3.4 to 2.3.6, but after upgrading to 2.3.7 and 2.3.8, our app is now throwing nullpointerexception. @component public class mycomponent { public void dowork() {} } then, let’s define our service class. In this tutorial, we’ll see common errors that lead to a nullpointerexception on an autowired field. Basically, spring is going to scan the project's classpath (or paths you specified), find all of the @component classes and make. One of the most common reasons for an @autowired field being null is that the spring container is not scanning the package where. Setter injection allows for optional dependencies, which can lead to null pointer exceptions if the dependencies are not properly checked for null values.
