我正在 Play 框架中开发一种元启发式算法，并且必须有一个无限期的超时。加载一个小时后，我收到以下错误：

[AskTimeoutException：超时]

有没有办法解决这个问题？谢谢。

编辑：

这是我的控制器

public static Result planificar() {
        Carga.cargarGlobales();
        Moacs moacs = new Moacs(cargarParametros());
        moacs.ejecutar(); // metaheuristics algorithm
        List<Solucion> soluciones =  moacs.getConjuntoPareto();            
        return ok(soluciones);
    }

你应该使它成为一个异步控制器：http ://www.playframework.com/documentation/2.2.x/JavaAsync

您可以将 Timeout 设置为一个非常大的值。从 Scala文档中，范围FiniteDuration仅限于 +-(2^63-1)ns，大约是 292 年。

例如，可以这样做：

(someActor ? someMsg)(365 Days).map { x => .... }
