【问题】
java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
【解决】
1.添加jar包啊
sqlservler: sqljdbc4.jar
oracle: classes12.jar
mysql: mysql。。。。。.jar.

====oracle的写法：=======
/*private static String driver="oracle.jdbc.driver.OracleDriver";
private static String url="jdbc:oracle:thin:@127.0.0.1:1521:hmaccp";
private static String user="scott";
private static String password="tiger";*/
=====sqlserver的写法：======
private static String driver="com.microsoft.sqlserver.jdbc.SQLServerDriver";
private static String url="jdbc:sqlserver://127.0.0.1:1433;DatabaseName=message";
private static String user="sa";
private static String password="123456";
public static Connection getConn(){
Connection conn=null;
try {
Class.forName(driver);
conn=DriverManager.getConnection(url,user,password);
System.out.println("dd");
} catch (Exception e) {
e.printStackTrace();
}
return conn;
}
public static void closeAll(Connection conn,Statement stmt,ResultSet rs){
if(rs!=null){
try {
rs.close();
} catch (Exception e) {
e.printStackTrace();
}
}
if(stmt!=null){
try {
stmt.close();
} catch (Exception e) {
e.printStackTrace();
}
}
if(conn!=null){
try {
conn.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
public static void main(String[] args) {
getConn();
}
