我可以 运行 一次规划同一项目的不同求解器吗？
Can I run planning on different solvers of the same project at a time?
这是间歇性发生的，我看不到它的模式。我的场景是我以编程方式创建 7 个求解器，并在创建每个求解器后，将其发送到计划。
有时只有 1 或 2 个求解器在求解。有时，5 个求解器甚至似乎没有收到请求 body，因为 best-solution 属性 为空，而在成功求解的求解器上，它不为空。

根据我对异常的基本理解，这是否意味着我一次只能执行一个计划？
您可以同时 运行 来自相同（或不同）SolverFactory 的多个 Solver 实例。 许多用户这样做，尤其是在多租户环境中。事实上，SolverFactory 的设计考虑到了这一点：SolverFactory 是线程安全的。请注意 Solver 不是。
从 optaplanner 7.32 开始。0.Final，只需使用 SolverManager（为 7.33 版本合并的文档章节，没有制作 7.32）：
// all these methods return immediately: the solving happens on a separate thread.
solverManager.solve(problem1, this::saveSolution);
solverManager.solve(problem2, this::saveSolution);
solverManager.solve(problem3, this::saveSolution);
我们没有 quarkus（即将推出）或 spring-boot (released) 集成为您注入 SolverManager。
这是间歇性发生的，我看不到它的模式。我的场景是我以编程方式创建 7 个求解器，并在创建每个求解器后，将其发送到计划。
有时只有 1 或 2 个求解器在求解。有时，5 个求解器甚至似乎没有收到请求 body，因为 best-solution 属性 为空，而在成功求解的求解器上，它不为空。

根据我对异常的基本理解，这是否意味着我一次只能执行一个计划？
您可以同时 运行 来自相同（或不同）SolverFactory 的多个 Solver 实例。 许多用户这样做，尤其是在多租户环境中。事实上，SolverFactory 的设计考虑到了这一点：SolverFactory 是线程安全的。请注意 Solver 不是。
从 optaplanner 7.32 开始。0.Final，只需使用 SolverManager（为 7.33 版本合并的文档章节，没有制作 7.32）：
// all these methods return immediately: the solving happens on a separate thread.
solverManager.solve(problem1, this::saveSolution);
solverManager.solve(problem2, this::saveSolution);
solverManager.solve(problem3, this::saveSolution);
我们没有 quarkus（即将推出）或 spring-boot (released) 集成为您注入 SolverManager。
