我正在域名financial-datasite.rhcloud.com下的OpenShift上使用Spring MVC运行Tomcat7应用程序。我使用Tomcat服务器在本地运行并测试应用程序，然后将其推送到远程存储库。目前，只有一个主页和下面的按钮重定向到不同的页面。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HomePage，单击该按钮时，出现HTTP 404错误。我在这里遇到过各种类似的问题，但到目前为止他们都没有帮助过。我已经玩过配置web.xml，pom.xml，servlet-context.xml和控制器文件。但是，这些都没有帮助。我一直在检查tail files and logs以监视正在发生的事情，这表明远程服务器正在第二页的控制器类中访问一些'printWelcome'方法（在我的项目中甚至不存在）： / p>
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localhost中，默认页面以localhost:8181/mvc/运行，第二页以http://localhost:8181/mvc/Sectors运行。同样，在部署之后，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，这也是甚至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，因为我已经编码了要记录的打印命令，当从部署的站点请求页面时，这些命令实际上没有登录到控制台。我不确定在远程服务器上运行哪些文件，以及是否有任何我不知道的配置问题。以下是我的web.xml，pom.xml，servlet-context.xml，Sectors.jsp，我调用新页面的Google-Maps.js以及SectorController.java（它是用于控制器的文件）第二页）。对于一个冗长的问题道歉，如果您需要更多信息，请告诉我。任何帮助将不胜感激，谢谢。

答案 0 :(得分：4)
正如Jessai在评论中指出的那样，
var _Window = window.open('/mvc/Sectors', '__blank');
请勿明确使用您的项目名称！有一种方法可以获取您的上下文名称，例如HttpServletRequest的request.getContextPath（）方法。
在这种情况下，使用硬编码的URL字符串，我认为您可以使用相对URL，只需使用“Sectors”或“./Sectors”。
参考文献：
'__ blank'：你的意思是'_blank'？
顺便说一下：
您正在Tomcat 7上进行部署，因此您可以在web.xml文件中声明遵守Servlet 3.0规范而不是2.5。
请参阅以下内容以禁用启动时扫描的组件：
https://wiki.apache.org/tomcat/HowTo/FasterStartUp#Configure_your_web_application
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)
如果您的类文件与源代码不匹配，则表示您的代码尚未编译。删除已编译的类（例如，使用mvn clean），然后重试。
如果您感到好奇，可以使用任何ZIP存档应用程序解压缩war文件并查看实际存在的内容。
您或我们公司是否拥有http://spring.com网站的域名？如果没有，请勿使用包名com.spring，不要使用<groupId>com.spring</groupId>。这些名字不属于你。他们是别人的财产。
在
<org.springframework-version>3.1.1.RELEASE</org.springframework-version>
如果您使用的是3.x，为什么不在3.x系列中使用当前的3.2.12.RELEASE，或者更好的是4.1.6.RELEASE？ Spring Framework 3.1.x已达到使用寿命，不再受支持。
