Question

我已经用spring和hibernate创建了一个maven项目。我在这个项目中配置了tomcat 8.5。第一次尝试运行tomcat服务器时，http://localhost:8080/不起作用。我在google中搜索，发现需要在tomcat中进行一些配置：

步骤：

在Tomcat服务器上，单击鼠标右键>“属性”
在“常规”菜单中：单击“切换位置”
位置已从[工作区元数据]更改为localhost.server上的/ Server / Tomcat v8.5服务器

完成此配置后，我再次启动了tomcat服务器，http://localhost:8080/现在正在工作。我可以看到Tomcat欢迎页面

但是当我尝试访问http://localhost:8080/EventryApp/hello.jsp时，它不起作用。

错误是：

HTTP Status 404 – Not Found

在日志文件中是：

127.0.0.1 - - [04/Oct/2018:09:42:30 -0300] "GET /EventryApp/hello.jsp HTTP/1.1" 404 1098

能帮我理解这个问题吗？

关注我的设置文件：

首先。对于您的本地雄猫所在的测试或开发目的，我都无所谓。我正在使用标准服务器位置（使用工作空间元数据）。但这与您的问题无关。

第二，您必须配置应用程序的基本路径。通常，这是在将应用程序添加到服务器时完成的（例如，使用Eclipse时）

如果这不是自动完成的，那么您必须在server.xml文件中写入以下内容

<Context docBase="myApp" path="/myApp" reloadable="true" source="org.eclipse.jst.jee.server:myApp"/>

这使您的应用程序在“ http://localhost:8080/myApp”下可用

第三，您需要配置一个控制器来处理对该URL的请求。通常，您将需要类似登录公式的内容。

@Controller
@RequestMapping(value="/")
@Scope(value="session")
public class MainController {

  @RequestMapping
  public ModelAndView mainView() {
    ModelAndView mav = getModelAndView("mainView");
    return mav;
  }

}

我看到您有两个servlet定义。您是否真的想为您的应用程序提供多个上下文？您可能要结合这两个。

Tomcat在http：// localhost：8080 /中运行，但是在尝试http：// localhost：8080 / page / home.jsp
