今天我在连接mysql出现了以下问题 ，求老鸟解决
我才学数据库
package mysql;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;
public class InsertIntDemo02 {
public final static String DBDRIVER = "org.gjt.mm.mysql.Driver";
public static final String DBURL = "jdbc:mysql://localhost:3360/mldn";
public static final String DBUSE = "root";
public static final String DBPASS = "mysqladmin";
public static void main(String[] args) {
Connection conn = null;
Statement stmt = null;
String sql = "INSERT INTO user(name,password,age,sex,birthday)"
+ "VALUES('粒子','abcd',12,'女','1991-11-23')";
try {
Class.forName(DBDRIVER);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
try {
conn = DriverManager.getConnection(DBURL, DBUSE, DBPASS);
} catch (SQLException e) {
e.printStackTrace();
}
try {
stmt=conn.createStatement();
} catch (SQLException e) {
e.printStackTrace();
}
try {
stmt.executeUpdate(sql);
} catch (SQLException e) {
e.printStackTrace();
}
try {
stmt.close();
} catch (SQLException e) {
e.printStackTrace();
}
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
这个代码运行出现这种结果：
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure
