java - Play : Using a configuration property as the value of an annotation

Question

这(显然)有效:

@Every("10s")
public class Extinguisher extends Job {
    ...
}

...但这不是:

@Every(Play.configuration.getProperty("my.setting", "10s"))
public class Extinguisher extends Job {
    ...
}

当运行 auto-test 时，应用程序没有启动并提示我的 Controller 由于 javassist 遇到的 NullPointerException 而无法得到增强。

有没有办法从 application.conf 配置作业调度？

Answer 1

您可以从@OnApplicationStartup 作业手动安排您的作业:

@OnApplicationStartup
public class ExtinguisherBootstrap extends Job { 
    public void doJob() {
        new Extinguisher()
            .every(Play.configuration.getProperty("my.setting", "10s"));
    }
}
