How to load files/properties from WEB-INF directory?
提问by xyz
It seems that in my Tapestry app, I can't load ini files nor properties file from WEB-INF directory or class path.
似乎在我的 Tapestry 应用程序中，我无法从 WEB-INF 目录或类路径加载 ini 文件或属性文件。
I tried several different methods which should load my file but non of them worked.
我尝试了几种不同的方法，它们应该加载我的文件，但它们都不起作用。
- ex
- 前任
realm.setResourcePath("/WEB-INF/auth.properties");
realm.setResourcePath("/WEB-INF/auth.properties");
- ex
- 前任
realm.setResourcePath("classpath:wip/pages/auth.properties");
realm.setResourcePath("classpath:wip/pages/auth.properties");
I need to load properties/ini file in order to use tapestry-security module which is based on Shiro.
我需要加载 properties/ini 文件才能使用基于 Shiro 的挂毯安全模块。
Thanks for help !

The root of the classpath is the way to go. Put your file in src/main/resources/auth.propertiesthen set your resourcePathusing realm.setResourcePath("classpath:auth.properties");
类路径的根是要走的路。将您的文件放在src/main/resources/auth.properties 中，然后使用 realm.setResourcePath("classpath:auth.properties");设置您的资源路径。
Check the ExtendedPropertiesRealmand the tapestry-security testapp for an example

Try ServletContext.getResourceAsStream("/WEB-INF/auth.properties")or ServletContext.getResourceAsStream("WEB-INF/auth.properties")
尝试ServletContext.getResourceAsStream("/WEB-INF/auth.properties")或ServletContext.getResourceAsStream("WEB-INF/auth.properties")
ServletContext has to be use from servlet, servletListener etc.
ServletContext 必须在 servlet、servletListener 等中使用。

Try
尝试
Properties props = new Properties();
props.load(new FileInputStream(new File(req.getServletContext().getRealPath("/WEB-INF/fileName.properties"))));
System.out.println(props);

I found the easiest way was to
我发现最简单的方法是
put file in src/main/resources/config.properties. This will be put in /WEB-INF/classes/config.properties when the project is compiled by maven into WAR
read the file from a servlet with the following
InputStreaminputStream = getClass().getClassLoader().getResourceAsStream("config.properties");
将文件放在 src/main/resources/config.properties 中。这个会在maven编译成WAR的时候放在/WEB-INF/classes/config.properties
使用以下命令从 servlet 读取文件
InputStreaminputStream = getClass().getClassLoader().getResourceAsStream("config.properties");
