There is an HTML template under our D drive, and now all we have to do is parse the News.template file, extract the data from the database, add the data to the specified template location

12<title>{title}</title>34<body>5<table align="Center"Width=" the"Border="1">6<tr>7&LT;TD width="10%"><b> label:</b></td>8<td>{title}</td>9</tr>Ten<tr> One&LT;TD width="10%"><b> author:</b></td> A<td>{author}</td> -</tr> -<tr> the&LT;TD width="10%"><b> Time:</b></td> -<td>{createTime}</td> -</tr> -<tr> +&LT;TD width="10%"><b> content:</b></td> -<td>{content}</td> +</tr> A</table> at</body>
news.template

Next use the IO stream's inputstream to read the file into memory

1 //reading HTML template files New.template2      Publicstring ReadFile (String path) throws ioexception{3InputStream is=NULL;4String result="";5         Try {6@SuppressWarnings ("Unused")7             intData=0;8             byte[] by =New byte[1024x768];9              is=NewFileInputStream (path);Ten              while((data= is. Read (by))!=-1){ One                 //result+= (char) data; A                 //result=new String (data); -result=NewString (By,0, by.length); -             } the}Catch(FileNotFoundException e) { -System. out. println ("new.template file not found! "); - e.printstacktrace (); -         } +         finally{ -System. out. println ("Create success! "); +              is. Close (); A         } at         //return result.tostring (); -         returnresult; -}
string ReadFile (String path) throws IOException

Write Method tohtml () to replace the template file, create an HTML file for each news to display its information

1 //read the database table, get the News list information (do not explain here)2list<news> list =dao.allinfo ();3 //Write method replaces the placeholder "{}" in the News.template file with the data read from the database4String template= fileio.readfile ("D:\\news.template");5         6         //Replace the template file and create an HTML file for each news to display its information7          for(inti = 0; I < list.size (); i++) {8             //get a piece of news information9News news=List.get (i);Ten             //replace the corresponding placeholder with this news message OneString REPLACETR =NewString (); AReplacetr=template; -             //replace (char OldChar, char Newchar) returns a new string that is obtained by replacing all OldChar that appear in this string with Newchar . -Replacetr=replacetr.replace ("{title}", News.gettitle ()); theReplacetr=replacetr.replace ("{Author}", News.getauthor ()); -Replacetr=replacetr.replace ("{createtime}", News.getdatetime (). toString ()); -Replacetr=replacetr.replace ("{content}", News.getcontent ()); -             //generate an HTML file for this piece of news +String filepath= "D:\\dbtohtml\\new" +i+ ". html"; -              +Fileio.writefile (FILEPATH,REPLACETR);
toHtml () throws SQLException, IOException
