Question

当我在Tomcat 7中部署war文件时，我收到404错误页面。我可以在eclipse中从Jetty服务器运行我的应用程序，没有任何问题。我只是进行war导出并在Tomcat 7 webapps文件夹中部署应用程序并使用端口9090启动tomcat服务器，并返回404 not found错误。 Tomcat服务器启动成功，我的应用程序也是如此。我发现日志文件中没有错误。我的应用程序正常部署。我也尝试过添加一个欢迎文件列表，但它无效。

的web.xml

我的控制器类侦听“/”，“/ login”和“/ index”请求并相应地映射到登录页面和索引页面。

@RequestMapping(value="/", method=RequestMethod.GET)

@RequestMapping(value="/login", method=RequestMethod.GET)

@RequestMapping(value="/index", method=RequestMethod.GET)

以上映射在jetty服务器上运行良好。启动tomcat后，我可以在Webapp Manager页面中看到我的应用程序启动并运行设置为true。当我点击mywebapp时，它会显示404错误。

注意：war文件名和我访问的url都是相同的。我正在访问我的网址的网址是http://localhost:9090/mywebapp，战争文件名是mywebapp.war。

这是我的tomcat日志，

当我尝试访问http://localhost:9090/mywebapp url时，我在tomcat-stdout-xx中得到以下内容作为输出，

WARN [http-bio-9090-exec-5] servlet.DispatcherServlet (DispatcherServlet.java:1136) - No mapping found for HTTP request with URI [/mywebapp/] in DispatcherServlet with name 'mywebappServlet'

我的配置有什么问题？

Tomcat HTTP状态404未找到错误
