How to load files/properties from WEB-INF director

2019-08-04 04:16发布

问题:

It seems that in my Tapestry app, I can't load ini files nor properties file from WEB-INF directory or class path.

I tried several different methods which should load my file but non of them worked.

  1. ex

realm.setResourcePath("/WEB-INF/auth.properties");

  1. ex

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.

Thanks for help !

回答1:

The root of the classpath is the way to go. Put your file in src/main/resources/auth.properties then set your resourcePath using realm.setResourcePath("classpath:auth.properties");

Check the ExtendedPropertiesRealm and the tapestry-security testapp for an example

  • http://svn.codehaus.org/tynamo/trunk/tapestry-security/src/test/resources/shiro-users.properties



回答2:

Try ServletContext.getResourceAsStream("/WEB-INF/auth.properties") or ServletContext.getResourceAsStream("WEB-INF/auth.properties")

ServletContext has to be use from servlet, servletListener etc.

Try

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

  • 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");
