Consult, constructor has no effect

[beclass]

How does the constructor take effect when the bootstrapControllers is initialized？

For example, like this ok
export class App{
constructor(private name:string = "111"){
}
test(){
console.log(this.name)
console.log('test function')
}
}
const app = new App()
app.test()

This actually works now.
