在servlet中读取/写入文本文件，该文件应存储在JBoss中的什么位置? [英] Reading/writing a text file in a servlet, where should this file be stored in JBoss?

问题描述

我在JBoss中部署了servlet.我想根据客户端输入将数据读/写到文本文件中.该文本文件应放在JBoss目录结构的何处?

I have servlet deployed in JBoss. I want to read/write data into a text file based on the client input. Where should this text file be put in the JBoss directory structure?

推荐答案

/data目录用于此目录.

其绝对路径可由jboss.server.data.dir系统属性提供.

Its absolute path is available by the jboss.server.data.dir system property.

File dataDir = new File(System.getProperty("jboss.server.data.dir"));
File yourFile = new File(dataDir, "filename.ext");
// ...

请注意，您是通过这种方式将Web应用程序代码紧密耦合到特定服务器.如果要更改服务器，请记住将上述代码也更改为新服务器支持的(或不支持).

Note that you're this way tight-coupling the web application code to a specific server. If you ever want to change servers, keep in mind to change the above code as well to whatever the new server supports (or not).
