HarmonyOS 如何代码主动调用实现应用重启

let context = getContext(this) as common.UIAbilityContext 
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") 
  }) 
})
