我在域下的 OpenShift 上使用 Spring MVC 运行 Tomcat7 应用程序:financial-datasite.rhcloud.com .我使用 Tomcat 服务器在本地运行和测试应用程序，然后将其推送到远程存储库。目前，只有一个主页和一个重定向到不同页面的按钮。在本地测试时，两个页面都按预期显示内容。但是，当部署到远程服务器时，只显示主页，单击按钮时，出现 HTTP 404 错误。我在这里遇到过各种类似的问题，但到目前为止都没有帮助。我尝试过配置 web.xml、pom.xml、servlet-context.xml 和 Controller 文件。然而，这些都没有帮助。我也一直在检查 tail files and logs监视正在发生的事情，这表明远程服务器正在访问第二页 Controller 类中的某些“printWelcome”方法(我的项目中甚至不存在):

INFO : org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/Sectors],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.spring.mvc.SectorController.printWelcome(org.springframework.ui.ModelMap)

这是我的 project structure .在我的本地主机中，默认页面以 localhost:8181/mvc/ 运行，第二个页面以 http://localhost:8181/mvc/Sectors 运行。同样，部署后，主页运行为 http://financial-datasite.rhcloud.com第二页执行为 http://financial-datasite.rhcloud.com/Sectors ，这会为/WEB-INF/views/hello.jsp 引发 404 错误，同样，它甚至不存在于我的项目目录中。我在日志文件中观察到的另一件事是，代码可能没有命中 SectorController 类，因为我已经为要记录的打印命令编写了代码，当从已部署站点请求页面时，这些命令并没有真正登录到控制台中。我非常不确定远程服务器上正在运行哪些文件，以及是否存在我不知道的任何配置问题。以下是我调用新页面加载的 web.xml、pom.xml、servlet-context.xml、Sectors.jsp、Google-Maps.js)和 SectorController.java(这是用于的 Controller 文件第二页)。很抱歉问题很长，如果您需要更多信息，请告诉我。任何帮助将不胜感激，谢谢。

最佳答案

1. 正如 Jessai 在评论中指出的那样，

   var _Window = window.open('/mvc/Sectors', '__blank');
   

   不要明确使用您的项目名称!有一些方法可以获取上下文名称，例如 HttpServletRequest 的 request.getContextPath() 方法。

   在这种使用硬编码 URL 字符串的情况下，我认为您可以使用相对 URL，只需“Sectors”或“./Sectors”。

   引用资料:

   • https://developer.mozilla.org/en-US/docs/Web/API/Window/open
   • http://www.w3.org/TR/html5/browsers.html#dom-open

2. '__blank' :你的意思是 '_blank' ？

3. 顺便说一句:

   INFO : org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping - Mapped "{[/Sectors],methods=[GET],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public java.lang.String com.spring.mvc.SectorController.printWelcome(org.springframework.ui.ModelMap)

6. 开启

   <org.springframework-version>3.1.1.RELEASE</org.springframework-version>
   

   如果您使用的是 3.x，为什么不使用 3.x 系列中的当前 3.2.12.RELEASE，或者更好的最后一个 4.1.6.RELEASE？ Spring Framework 3.1.x 的生命周期已结束，不再受支持。
