JSP static news page generation (3)

1. Modify the file editor ewebeditor used to add news content

2. Store the file name and title in the database to facilitate the foreground to call these generated static news pages.

 

 

1. An error occurred while displaying the image after ewebeditor was added.
Generated is

However, this static news page is in the folder, so

(Note: Here I set this project to the root directory)
Solution:
String article = new string (request. getparameter ("article"). getbytes ("iso-8859-1"), "gb2312 ");
Int Index = article. indexof ("IMG ");
System. Out. Print (Article); //
If (article. indexof ("IMG")> 0)
{
Article = article. replaceall ("/uploadfile", "../uploadfile ");
}
System. Out. Print (Article); //

2. Insert the database (generated HTML, such as 2008-07-16/1216200066859. html, song name, and add time)
Create Table 'smusic '(
'Id' int (11) not null auto_increment,
'Name' varchar (100) default null,
'Filesrc' text,
'Singer _ id' varchar (11) default null,
'Type _ id' varchar (11) default & apos; 1 & apos ;,
'Special _ id' int (11) default & apos; 0 & apos ;,
'Tuian Ian 'int (11) default & apos; 0 & apos ;,
'Redian 'int (11) default & apos; 0 & apos ;,
'News' int (11) default & apos; 0 & apos ;,
'Publictime' datetime default null,
Primary Key ('id ')
) Type = MyISAM;
