HarmonyOS QT框架，QProcess::startDetached无法重新启动应用程序

调用appRecovery.restartApp()接口，可以重启应用。需要配置：

1.在module.json5中的srcEntry：添加

"srcEntry": "./ets/abilitystage/abilitystage.ets",

2.module.json5中配置支持恢复的Ability：

"abilities": [
{
  "name": "EntryAbility",
  "recoverable": true,
}
]

3.新建AbilityStage类： ./ets/abilitystage/abilitystage.ets：

import appRecovery from '@ohos.app.ability.appRecovery';
import AbilityStage from '@ohos.app.ability.AbilityStage';
import Want from '@ohos.app.ability.Want';

export default class MyAbilityStage extends AbilityStage {
  onCreate(): void {
    appRecovery.enableAppRecovery(
      appRecovery.RestartFlag.ALWAYS_RESTART,
      appRecovery.SaveOccasionFlag.SAVE_WHEN_ERROR,
      appRecovery.SaveModeFlag.SAVE_WITH_FILE
    );

    let want: Want ={
      bundleName:'com.example.pagesrouter',
      abilityName:"EntryAbility"
    }
    appRecovery.setRestartWant(want)
  };
};
