JAVA获取服务器路径的方法-飞外

ServletContext sc = (ServletContext)FacesContext.getCurrentInstance().getExternalContext().getContext();
文件的绝对路径
request.getSession().getServletContext().getRealPath(request.getRequestURI())
当前web应用的绝对路径
servletConfig.getServletContext().getRealPath(“/”);
3、jsp中获取服务器路径


String contextPath = request.getContextPath(); String realPath = request.getSession().getServletContext().getRealPath("/"); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+contextPath+"/";
contextPath =”/项目名称”; //获取的是项目的相对路径
realPath = F: omcat_homewebapps项目名称 //获取的是项目的绝对路径
basePath = http://localhost:8080/项目名称/ //获取的是服务的访问地址
4、ServletContext对象获得几种方式


Javax.servlet.http.HttpSession.getServletContext() Javax.servlet.jsp.PageContext.getServletContext()Javax.servlet.ServletConfig.getServletContext()

文件的绝对路径
request.getSession().getServletContext().getRealPath(request.getRequestURI())
当前web应用的绝对路径
servletConfig.getServletContext().getRealPath(“/”);
