quarkus - Optaplanner Quarkus 反射问题

问题描述

我正在使用内置的基于 XML 文件创建求解器工厂

solverFactory = SolverFactory.createFromXmlResource("solverConfig.xml");

这在编译成 Quarkus 原生应用程序之前工作正常，现在我从 Optaplanner 枚举中得到反射问题：

我可以通过在我的类调用上添加@RegisterForReflection 来解决这些问题SolverFactory.createFromXmlResource("solverConfig.xml")，但感觉这些反射注册不应该是手动步骤。目前我在@RegisterForReflection(targets = {EnvironmentMode.class, RandomType.class, DomainAccessType.class})，但我猜会有更多的枚举添加到该列表中......它真的应该这么复杂吗？我正在使用 Quarkus Optaplanner 依赖项

<dependency>
  <groupId>org.optaplanner</groupId>
  <artifactId>optaplanner-quarkus</artifactId>
</dependency>

解决方案

通过另一种方式，我能够解决这个问题。

在我之前调用的类中solverFactory = SolverFactory.createFromXmlResource("solverConfig.xml")，我现在只注入工厂：

@Inject
SolverFactory<Schedule> solverFactory;

并将 XML 文件名移至 application.properties：

quarkus.optaplanner.solver-config-xml=solverConfig.xml
