我使用 eclipse 完成了一个小型 Web 开发项目。当我尝试使用 url 在浏览器上运行它时，它运行良好localhost:8080/myproject/home.html。但是，如果我想在另一台机器（使用同一 wifi 的笔记本电脑、手机等）上访问它，则是不可能的；它无法连接。
在谷歌搜索了一段时间后，我发现我必须使用 IP 地址而不是“localhost”。所以我试了一下10.0.0.4:8080/myproject/home.html，但仍然不起作用。事实上，我无法在同一台机器上打开该网址（该机器localhost:8080/myproject/home.html运行正常）。我还在控制面板防火墙设置中添加了一条新的入站规则，允许访问 TCP 协议的所有端口。使用该网址运行应用程序仍然有问题10.0.0.4:8080/myproject/home.html（在同一台机器上以及笔记本电脑和手机上）。
仅供参考，我正在使用 Eclipse Indigo、Apache tomcat 6.0 和 server.xml 文件内容如下：

答案1
也许你应该将服务器绑定到 0.0.0.0 而不是 127.0.0.1
答案2
从 eclipse 运行的本地 tomcat 服务器默认绑定到 localhost（127.0.0.1），这意味着它将只接受该地址的请求。
当您尝试从计算机的 IP 地址访问它时，它会被拒绝，因为请求的是 10.0.0.4，而服务器未绑定到该地址。这解释了为什么您无法在同一台计算机上通过该 IP 访问它。
这应该解释如何绑定到另一个 IP 地址。
