Jsp connection to mysql ---------- first technical article _ MySQL

Jsp connects to mysql ---------- The first technical article that connects to mysql for one day today.

Finally, I decided to start learning jsp from scratch, saving me the trouble.

After a full night of work, I finally connected the database. However, it's so sad that I even have a database...

<% @ Page language = "java" import = "java. util. * "pageEncoding =" UTF-8 "%> <% @ page import =" data. database "%> <% @ page import =" java. SQL. * "%> <% String path = request. getContextPath (); String basePath = request. getScheme () + ": //" + request. getServerName () + ":" + request. getServerPort () + path + "/"; %>My JSP 'index. jsp 'starting page
 
 
 
 
 
 This is my JSP page.
<% String server = "localhost"; // MYSQL server address String dbname = "rowanhao"; // MYSQL database name String user = "root "; // MYSQL database logon username String pass = "zp930710"; // MYSQL database logon password String port = "3306"; // SQL Server port number, the default value is 1433 String url = "jdbc: mysql: //" + server + ":" + port + "/" + dbname + "? User = "+ user +" & password = "+ pass +" & useUnicode = true & characterEncoding = GB2312 "; Class. forName ("org. gjt. mm. mysql. driver "). newInstance (); Connection conn = DriverManager. getConnection (url); Statement stmt = conn. createStatement (ResultSet. TYPE_SCROLL_SENSITIVE, ResultSet. CONCUR_UPDATABLE); String SQL = "select * from student"; ResultSet rs1_stmt.exe cuteQuery (SQL); while (rs. next () {out. println (rs. getString (1);} rs. close (); out. println ("aaa"); %>
