所以我使用Socket和ServerSocket类编写了一个程序。但是,如果服务器和客户端都在同一台计算机上,并且客户端连接到localhost(127.0.0.1),我只能连接到我的服务器。即使两者在同一台机器上,我也无法使用常规IP地址进行连接:我必须使用127.0.0.1。如何设置服务器以便可以从任何计算机连接到服务器?
我正在使用Java中的网络教程(http://docs.oracle.com/javase/tutorial/networking/sockets/clientServer.html)。
这是来自客户端的堆栈跟踪: java.net.ConnectException:连接超时:连接 at java.net.DualStackPlainSocketImpl.connect0(Native Method) 在java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:69) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:200) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182) 在java.net.PlainSocketImpl.connect(PlainSocketImpl.java:157) 在java.net.SocksSocketImpl.connect(SocksSocketImpl.java:391) 在java.net.Socket.connect(Socket.java:579) 在java.net.Socket.connect(Socket.java:528) 在java.net.Socket。(Socket.java:425) 在java.net.Socket。(Socket.java:208) 在client.Client.connect(Client.java:38) at client.ClientUI $ 2.mouseClicked(ClientUI.java:87) 在java.awt.AWTEventMulticaster.mouseClicked(AWTEventMulticaster.java:269) at java.awt.Component.processMouseEvent(Component.java:6508) 在javax.swing.JComponent.processMouseEvent(JComponent.java:3321) at java.awt.Component.processEvent(Component.java:6270) at java.awt.Container.processEvent(Container.java:2229) at java.awt.Component.dispatchEventImpl(Component.java:4861) at java.awt.Container.dispatchEventImpl(Container.java:2287) at java.awt.Component.dispatchEvent(Component.java:4687) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4832) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4501) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4422) at java.awt.Container.dispatchEventImpl(Container.java:2273) at java.awt.Window.dispatchEventImpl(Window.java:2719) at java.awt.Component.dispatchEvent(Component.java:4687) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:729) at java.awt.EventQueue.access $ 200(EventQueue.java:103) at java.awt.EventQueue $ 3.run(EventQueue.java:688) at java.awt.EventQueue $ 3.run(EventQueue.java:686) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain $ 1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.security.ProtectionDomain $ 1.doIntersectionPrivilege(ProtectionDomain.java:87) at java.awt.EventQueue $ 4.run(EventQueue.java:702) at java.awt.EventQueue $ 4.run(EventQueue.java:700) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain $ 1.doIntersectionPrivilege(ProtectionDomain.java:76) at java.awt.EventQueue.dispatchEvent(EventQueue.java:699) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:161) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:150) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:146) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:138) at java.awt.EventDispatchThread.run(EventDispatchThread.java:91) Java结果:-1

不幸的是,您既没有发送代码也没有发送堆栈跟踪,因此无法发现您的问题。
但是,我可以假设您可能已被计算机上运行的个人防火墙阻止。从一台机器搬到两台机器时,这是一个典型的问题。发现这一点:在两台机器上首先停止防火墙(如果它正在运行)。如果它有助于配置允许客户端连接到服务器的规则(在防火墙规则中配置端口和可能的IP。)

检查您的操作系统防火墙和可能包含防火墙的防病毒程序。正如AlexR建议的那样,您可以禁用所有防火墙和防病毒软件,如果连接成功,您可以向防火墙添加允许连接所需的规则......
