コンソールからの出力をlocalhostに取得する：8080

Question

コンソールからブラウザへの出力を正しく取得する方法https://localhost:8080/。私は他の小さなspring mvcの快適なWeb​​サービスプロジェクトに取り組んでいました。私はlocalhost：8080の日付をスムーズにすることができました。

ここでは、出力の一部されています

Customer: Customer [userId=1, forename=homer, lastname=simpson, email=hsimpson@springfield.com, mobileNumber=0781 123 456, password=marge, orders=[ 
Order [orderId=0 total Order cost: 86.9, orderItems=[ 
OrderItem [item=Item [title=Dummies Guide to Dummies, publisher=Red Penguin, price=10.45, yearPublished=2014] Book [author=Man Equine], count=2 total cost=20.9], 
OrderItem [item=Item [title=Release the hounds, publisher=Red Penguin, price=22.0, yearPublished=2014] Book [author=Rufus Ruff], count=3 total cost=66.0]]], 

どちらか

Whitelabel Error Page 
    This application has no explicit mapping for /error, so you are seeing this as a fallback. 
    Wed Mar 22 23:20:49 EET 2017 
    There was an unexpected error (type=Not Found, status=404). 
    No message available 

それとも

Firefox can't establish a connection to the server at localhost:8080.

Webサーバーのログにはアクセスできません。また、そのようにする必要もありません。また、サーバーがlocalhost上でのみ実行されている場合、Webサーバーを実行しているコンピューターのみがWebサーバーにアクセスできます。

あなたがここで達成しようとしていることとネットワークがどのようなものかを言うことは難しいです。私はあなたがあるマシン上で動作しているWebサーバーを持っていて、別のマシンからアクセスしようとしていると仮定しています。より多くの情報を提供する必要があります。
