The lessonList has an @PlanningEntityCollectionProperty annotation, so OptaPlanner can change them during solving and your TimeTableConstraintProvider can select from those too. The values of the timeslot and room fields are typically still null, so unassigned. // A room can accommodate at most one lesson at the same time. Determining the @PlanningVariable fields for an arbitrary constraint solving use case is often challenging the first time. Read the domain modeling guidelines to avoid common pitfalls.
In this course, instructor Dan Vega, a popular Spring framework instructor on Udemy will teach you how to develop a web application using Spring Boot. Spring Boot gives you options to create a JAR or WAR file and the best thing is that you can even run the WAR file from the command prompt because Spring Boot has an embedded tomcat server in it. If it adheres to all hard constraints, then it is a feasible solution, for example, a solution with the score 0hard/-7soft.

Notice that the type declarations call the constructor from within the class with their name values. Notice how we annotate our method with @Controller instead of @RestController this time. The @RestController annotation implies that the controller will return a REST response whereas a @Controller can return pre-rendered views/HTML. Thymeleaf is a template engine for Spring that allows us to create UIs and display our model data to the users. We basically removed the DTO-related code from the UserService class and replaced the return types with User. We will delete the controllers because we do not want to expose the functionality of modifying our data anymore.
