应用如何在没有任何异常的情况下重启应用自身

onPageShow(): void { 
  context.terminateSelf().then(() => { 
    console.log("应用即将被关闭") 
    let want: Want = { 
      bundleName: 'com.example.myapplication', 
      abilityName: 'EntryAbility' 
    } 
    context.startAbility(want).then(() => { 
      console.log("应用被启动") 
    }) 
  }) 
}
