Java ways to get web roots I currently use two kinds of:

1, get the class method where the directory interception root directory

Get its class directory
//execution path to/d:/workspace/tourservice/webcontent/web-inf/classes/String in class Freemarkerutil
 Path = FreemarkerUtil.class.getClassLoader (). GetResource (""). GetPath ();

After execution RootPath is/d:/workspace/tourservice/webcontent
 String rootpath = path.substring (0, Path.indexof ("/WEB-INF/ "));
RootPath is the root directory for the Web project.

2, get root directory through spring configuration

Add the following code to the Web.xml

    <context-param>
        <param-name>webAppRootKey</param-name>
        <param-value> b2cweb.root</param-value>
    </context-param>

    <listener>
        <listener-class> Org.springframework.web.util.webapprootlistener</listener-class>
    </listener>
Get the root directory in the class as follows

After execution RootPath is/d:/workspace/tourservice/webcontent
String rootpath = System.getproperty ("B2cweb.root");
