完整的获取当前jsp文件路径的语句

错误：

String realPath = "http://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath();

String realPath = "http://" + request.getServerName() + ":" + request.getServerPort() + request.getServletPath();

正确：

String realPath = "http://" + request.getServerName() + ":" + request.getServerPort() + request.getContextPath()+request.getServletPath().substring(0,request.getServletPath().lastIndexOf("/")+1);
