[英]Java Webapp Cannot Find Local Server Directory
I have a Spring MVC 3.1 webapp running on Tomcat 5.5 on a CentOS server. 我有一个在CentOS服务器上的Tomcat 5.5上运行的Spring MVC 3.1 Web应用程序。 I have a controller that checks for the existence of a file located on a network share, which is mounted on the server ( /netshare/data/
). 我有一个控制器,用于检查是否存在网络共享文件,该文件已安装在服务器( /netshare/data/
)上。 My application cannot seem to see this directory, however when I run a standalone java app with the same code, it is able to locate the directory and its contained files without error. 我的应用程序似乎看不到该目录,但是当我使用相同的代码运行独立的Java应用程序时,它能够找到该目录及其包含的文件,而不会出现错误。 Is there some configuration that needs to be done in Tomcat so that directories outside the webapp can be referenced by Java? 是否需要在Tomcat中进行一些配置,以便Java可以引用webapp之外的目录?
Here is my controller class: 这是我的控制器类:
@Controller
@RequestMapping("/Test")
public class TestController {
@RequestMapping(method=RequestMethod.GET)
public String showTest(Model model){
List<String> messages = new ArrayList<String>();
File dirTest = new File("/netshare/data");
if (dirTest.isDirectory()){
messages.add("Base directory found successfully!");
File dataFileDir = new File("/netshare/data/dataFiles/");
Integer fileId = 8000;
File dataFile = new File(dataFileDir, fileId.toString() + ".pdf");
if (dataFile.exists()){
messages.add("Data file found!");
}
else {
messages.add("Data file NOT found!");
}
}
else {
messages.add("Base directory not found!");
}
model.addAttribute("messages", messages);
return "test";
}
Turns out it was a permissions issue with the Isilon server being accessed by the web server, and not an issue with either my webapp or Tomcat's configuration. 事实证明,这是Web服务器正在访问Isilon服务器的权限问题,而不是Webapp或Tomcat的配置问题。 Thank you everyone for the help. 谢谢大家的帮助。
