HarmonyOS如何实现重启应用

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

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) 
  }; 
};

"module": { 
  "name": "entry", 
  "srcEntry": "./ets/entryability/MyAbilityStage.ets",

appRecovery.restartApp(); 
onClick(() => { 
  appRecovery.restartApp(); 
})

//方案二 
this.context.terminateSelf(()=>{ 
  Logger.info("应用即将被关闭"); 
  let want: Want ={ 
    bundleName:'com.example.pagesrouter', 
    abilityName:"EntryAbility" 
  } 
  this.context.startAbility(want).then(()=>{ 
    Logger.info("应用被启动"); 
  }) 
})
