連接mysql,代碼都沒錯誤,驅動很到位。並且在連接數據庫成功率很高的情況下,老是報驅動找不到的錯,快吐血了都。最後解決的竟然是方法是:全部重啓,代碼重新寫一遍,驅動重新載入一遍。
連數據庫只是前菜,後面的插入數據纔是重頭戲。
代碼如下:
public class BlogServlet_1 extends HttpServlet {
private static final long serialVersionUID = 1L;
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("utf-8");
String title = request.getParameter("title");
String category = request.getParameter("category");
String content = request.getParameter("content");
try {
Class.forName("com.mysql.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost/blog?user=root&password=123");
String sql = "insert into blog (blo_id,title,content,create_time) value (?,?,?,now())";
java.sql.PreparedStatement pst = conn.prepareStatement(sql);
pst.setInt(1, Integer.parseInt(category));
pst.setString(2, title);
pst.setString(3, content);
int result = pst.executeUpdate();
System.out.println(result);
} catch (SQLException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doGet(request,response);
}
}
連着前面的jsp頁面能夠實現數據的插入。
