Spring Web MVC 404错误——以root身份部署在Tomcat服务器上

Question

我快疯了。请帮助。

我是Spring的新手，我使用sts/eclipse开发了我的第一个Spring mvc web应用程序。它可以在eclipse的tomcat服务器中完美运行。

应用程序上下文是/realtyguide，我在eclipse中运行它在http://localhost:8080/realtyguide/

这是我的web.xml

<?xml version="1.0" encoding="UTF-8"?>

这是根

的控制器处理程序方法

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

        Model model) {
    model.addAttribute("searchFormBean", searchFormBean);
    // 'index' is a Tile definition in tiles.xml
    return "index.tiledef";
}

我的目标

在example.com处调出网站的索引页，在域名后去掉额外的/.../。

我做了什么

作为虚拟主机的根节点部署在共享的web主机上:

我在stackoverflow上读到我需要作为根部署所以…

我将它打包在STS/Eclipse中:右键单击项目"realtyguide"> Run as> Maven包

Webhost服务器是私有的Tomcat 5.5。我在我的webhost上部署了war文件(解压缩它)作为虚拟主机的默认应用程序(在server.xml中使用上下文path = "")，这样我就可以访问example.com而不是example.com/realtyguide的网站。

成功。至少我是这么想的。我可以在http://example.com/

打开索引页。

访问从索引页引用的其他网页返回404错误:

请求的URL/realtyguide/page-name在此服务器上找不到

即使浏览器地址栏显示上下文路径与完整的URL http://www.example.com/realtyguide/page-name

我认为应用程序绕过了spring分派器servlet，因此无法识别请求URL中的上下文路径' realtyguide ' -导致404错误。

我不知道该如何处理这件事。

问题:

1. 我该怎么做才能在不破坏应用程序的情况下将网站的索引页放在example.com而不是example.com/realtyguide/ ?我已经尝试了index.jsp文件(在WEB-INF)转发到上下文路径的索引，但它没有解决问题。也许我做错了。

2. 是否有一些转发机制，我可以使用，以便网站访问者进入example.com，并立即转发到example.com/realtyguide/的索引页，以便所有url应由应用程序处理?

我思考问题的方式正确吗?你以前用过什么解决方案吗?

我非常感谢你的帮助。感谢您的宝贵时间。

Answer 1

您需要使您的web应用程序成为Tomcat的默认web应用程序。说明在这里:

http://wiki.apache.org/tomcat/HowTo How_do_I_make_my_web_application_be_the_Tomcat_default_application.3F

一旦完成，使用index.jsp转发到Spring应用程序的索引就很简单了。

WAR根目录下包含以下内容的index.jsp文件应该可以做到这一点:

<jsp:forward page="/realtyguide/" />
