springMVC获取项目真实路径

1、原生httpservletrequest

例如访问地址是：http://localhost:8080/test

request.getContextPath(); 获取到工程名称:    /test

request.getServletContext().getRealPath("/");  获取到实际路径例如：E:\Java\tomcat7\apache-tomcat-7.0.55\wtpwebapps\test\

2、shiro

shiro可以直接从shiro中获取request和session

ServletRequest request = ((WebSubject)SecurityUtils.getSubject()).getServletRequest(); HttpSession httpSession = ((HttpServletRequest)request).getSession(); logger.debug("httpSession.getServletContext():"+httpSession.getServletContext()); System.out.println(httpSession.getServletContext().getRealPath("/WEB-INF"));
