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);
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);
简单表单验证收藏
