jsp实验19 File
| 三、源代码以及执行结果截图： readJSPFile.jsp <%@ page contentType="text/html" %> <%@ page pageEncoding = "utf-8" %> <%@ page import="java.io.*"%> <style> #tom{ font-family:宋体;font-size:28;color:blue } </style> <HTML><body id =tom bgcolor=#FFBBFF> <% StringBuffer sourceCode=new StringBuffer(); request.setCharacterEncoding("utf-8"); String mess = request.getParameter("submit"); if(mess==null) mess=""; if(mess.contains("源码")){ response.setContentType("text/plain");
String path = request.getRealPath(request.getServletPath());
File jspFile=new File(path); try{ RandomAccessFile randomAccess = new RandomAccessFile(jspFile,"r"); String s=null; StringBuffer stringbuffer=new StringBuffer(); while ((s=randomAccess.readLine())!=null){ byte b[] = s.getBytes("iso-8859-1"); sourceCode.append("\n"+new String(b,"utf-8")); }
} catch(Exception exp){ out.println(exp); } } %> JSP文件源代码：<br> <%=sourceCode %> <br> <form action="" method=post > <input type="submit" id=tom name ="submit" value="看本页面的源码" /> </form> </body></HTML> 效果图
