Is it possible to add 2 PlanningSolution annotated class in a single project?

I am currently working on a project very much like meeting scheduling and I have to run the solver twice. The planning entity changes for the 2 solver, so I changed the planning solutions too and made the config.xml separate. I followed this blog to add multiple solver https://timefold.ai/blog/multiple-solver-managers but the spring boot application shows this error when I try to run it.

Yes it is possible to use multiple PlanningSolution classes in a single Spring boot project. However, in order to do so, you must use @Named solver managers with solver-config-xml specified in the applications.properties:

In your application.properties:

timefold.solver.teacherSolver.solver-config-xml=teachersConfig.xml
timefold.solver.roomSolver.solver-config-xml=roomsConfig.xml

In your Java code:

    @Autowired
    @Qualifier("teacherSolver")
    SolverManager<TeacherToLessonSchedule, String> teacherToLessonScheduleSolverManager;

    @Autowired
    @Qualifier("roomSolver")
    SolverManager<Timetable, String> lessonToRoomTimeslotSolverManager;

I had the xml in the resource and created the solver with out the @Autowired.

You are missing the timefold. prefix in your application.properties. It should look like this instead:

timefold.solver.workOrder.solver-config-xml=solver/workOrder/KsystemScheduleManagementApplicationSolverConfig.xml
timefold.solver.workOrderReverse.solver-config-xml=solver/workOrderReverse/ReverseKsystemScheduleManagementApplicationSolverConfig.xml

thank you.
