vue3中store分模块时其他vue页面中如何使用vuex中的actions mutations states

const state={
    userName: null
}

const actions = {
    login({commit}, userinfo){
        return new promise( (resolve, reject) => {
             loginByUserName(userinfo.userName, 
                        userinfo.password).then(res => {
             })

        } )
    
    }  
}

const mutations = {
    setAccount ( state, data ) {
        state.username = data.username
    }
}


export default {
   state,
   actions,
   mutations,
   namespaced: true
}

import { mapActions} from "vuex"

methods: {
      ...mapActions("account",["login"]), //映射account模块中的login方法
      
      submit(){
          this.login(userInfo)
      }
}
