主要原理請參考?id=233

經過一翻調試，成功了。。呵

附上源碼。。

JDK 1.5 +ECLIPSE +TOMCAT 5.0.28 + MYSQL 5.0

數(shù)據(jù)庫TEST　，表名news
字段：　id int 自動增長　, Title varchar(20) , Content varchar(200) , Author varchar(10)

makeFile.jsp

<%
Connection conn = DBconn.getConnection();
Statement stmt = conn.createStatement();
ResultSet Rs = stmt.executeQuery("select * from news");
System.out.println("success");

%>

<%

String filePath = request.getRealPath("/")+"template.htm";

System.out.println(filePath);

String templateContent;
FileInputStream fileinputstream = new FileInputStream(filePath);
int lenght = fileinputstream.available(); //available() 返回可以不受阻塞地從此文件輸入流中讀取的字節(jié)數(shù)。

byte bytes[] = new byte[lenght];

fileinputstream.read(bytes); //read(byte[] b) 從此輸入流中將最多 b.length 個字節(jié)的數(shù)據(jù)讀入一個字節(jié)數(shù)組中。

fileinputstream.close();
//templateContent = new String(bytes);
String title;
String content;
String author;
while(Rs.next())
{
templateContent = new String(bytes);//如果不用這句，則替換一次之后，templateContent中就沒有#**#標志了。所以要重新生成
{
conn.close();
}
if(stmt!=null)
{
stmt.close();
}

%>

//數(shù)據(jù)庫連接文件
