Intellij IDEA 14 和 Tomcat 8.0

【问题标题】：Intellij IDEA 14 and Tomcat 8.0Intellij IDEA 14 和 Tomcat 8.0
【发布时间】：2026-01-01 06:30:01
【问题描述】：

我是使用 Java 进行 Web 开发的新手，并尝试在 Intellij 14 + Tomcat 8.0 上运行我的第一个“Hello World”应用程序。每次我收到错误“404”。

没有 Intellij 的 Tomcat 可以在 http://localhost:8080/ 作为 Windows 7 服务上完美运行。

【问题讨论】：

标签： java intellij-idea tomcat8


【解决方案1】：

根据您的Deployment 屏幕截图选项卡，您必须将选项卡Server 上的字段Open browser 的值修复为值http://localhost:8080/JSFDemo，并使用此路径来处理从IDEA 运行的Web 应用程序。

【讨论】：

  • 将打开的浏览器字段从 localhost:8080 更改为 localhost:8080/JSFDemo 但仍然是 404 错误
  • 从 Intellij 地址 localhost:8080 启动 Tomcat 后也不起作用 404 错误
  • @mkoval ，您应该将tomcat的日志附加到您的问题中
  • 将 catalina.log 添加到问题中
