RESTful Web服務，如何通過互聯網從其他計算機訪問

Question

我有一種情況

1. 休息的Web應用程序（使用Spring框架）的窗口在本地主機上運行（Web服務器上的Apache Tomcat 8 10），PC連接到互聯網
2. 另一個人距離我2oo公里，想用我的郵遞員或Android應用程序打我的網絡服務。

這是我的tomcat servel.xml -

<?xml version='1.0' encoding='utf-8'?> 
    <Server port="8005" shutdown="SHUTDOWN"> 
    <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

<!--APR library loader. Documentation at /docs/apr.html -->

<!-- Prevent memory leaks due to use of particular java/javax APIs--> 
<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /> 
<Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /> 
<Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

<!-- A "Service" is a collection of one or more "Connectors" that share

如何實現這一目標？

Answer 1

Open ports to your router 

Open Port

Then search on google "What is my public IP" 
If your public ip is 127.0.0.1 
tomcat port is 8080 and opened port is 8080 and war name is abc 
then 127.0.0.1:8080/abc is accessible on internet
