Optaplanner和Quarkus求解器配置更新

Question

public PlannerSolution solve() {
    UUID problemId = UUID.randomUUID();
    SolverJob<PlannerSolution, UUID> solverJob;
    
    solverJob = solverManager.solve(problemId, problem);

    PlannerSolution solution;
    try {
      // Wait until the solving ends
      System.out.println("Waiting................");
      solution = solverJob.getFinalBestSolution();
      System.out.println("Done");
    } catch (InterruptedException | ExecutionException e) {
      throw new IllegalStateException("Solving failed.", e);
    }
    return solution;
  }

提前感谢！

若要更改默认的求解器配置，请在项目的类路径上创建XML配置文件。默认情况下，optaplanner-quarkus扩展尝试读取solverconfig.xml。在项目中，它应该位于：

.../src/main/resources/solverconfig.xml

配置文件的默认位置可以由application.properties中的quarkus.optaplanner.solver-config-xml属性重写。
