Optaplanner 和 Quarkus 求解器配置更新 [英] Optaplanner and Quarkus solver config update

问题描述

我正在使用 quarkus 和 optaplanner 开展一个项目，我正在尝试访问和修改求解器的配置、添加启发式、更改搜索算法等.

I'm working on a project with quarkus and optaplanner, and I'm trying to access and modify the configuration of the solver, to add heuristics, change search algorithm etc.

我使用的是solverJob 和solverManager，而quarkus 似乎对我隐藏了求解器的配置.我基本上遵循 Quarkus 教程的步骤(https://quarkus.io/guides/optaplanner).

I'm using a solverJob and a solverManager, and quarkus seems to be hiding from me the configuration of the solver. I'm basically following the steps of the Quarkus tutorial (https://quarkus.io/guides/optaplanner).

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;
  }

我也在使用constraintProvider API.有没有办法让我访问和修改由 quarkus 自动制作的这个配置?我已经尝试过使用 solverFactory 和 xml conf 文件的基本方法，但 quarkus 对此一点也不满意.

I'm also using the constraintProvider API. Is there a way for me to access and modify this config made automatically by quarkus ? I've tried the basic way with a solverFactory and xml conf file, but quarkus isn't happy about that at all.

先谢谢你！

推荐答案

要更改默认求解器配置，请在项目的类路径上创建 XML 配置文件.optaplanner-quarkus 扩展默认尝试读取 solverConfig.xml.在项目中，它应该位于:

To change the default solver configuration, create the XML configuration file on the project's classpath. The optaplanner-quarkus extension tries to read the solverConfig.xml by default. In the project, it should be located in:

.../src/main/resources/solverConfig.xml

配置文件的默认位置可以被application.properties中的属性quarkus.optaplanner.solver-config-xml覆盖.

The default location of the configuration file can be overridden by the property quarkus.optaplanner.solver-config-xml in the application.properties.
