JAVA连接Oracle的问题
这个是我下的一个代码 有一些看不懂 请教各位大哥
ClassPath=.;E:\j2sdk14\lib\tools.jar;E:\oracle\ora90\jdbc\lib\classes12.zip
测试的电脑已经装好Oracle客户端，而且用SQLplus可以连接上。
/*
* This sample shows how to list all the names from the EMP table
*
* It uses the JDBC THIN driver. See the same program in the
* oci8 samples directory to see how to use the other drivers.
*/
// You need to import the java.sql package to use JDBC
import java.sql.*;
class Test
{
public static void main (String args [])
throws SQLException
{
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
/* try{
Class.forName( "oracle.jdbc.driver.OracleDriver ");
}catch(Exception e){
System.out.println( "No Driver! ");
}
*/
// Connect to the database
// You must put a database name after the @ sign in the connection URL.
// You can use either the fully specified SQL*net syntax or a short cut
// syntax as <host> : <port> : <sid> . The example uses the short cut syntax.
String url = "jdbc:oracle:thin:@172.28.31.85:1521:YIKATONG ";
String userName = "scott ";
String password = "tiger ";
if (args.length > 0) url = args[0];
if (args.length > 1) userName = args[1];
if (args.length > 2) password = args[2];
System.out.println(url);
System.out.println(userName);
System.out.println(password);
Connection conn =
DriverManager.getConnection (url, userName, password);
// Create a Statement
Statement stmt = conn.createStatement ();
// Select the ENAME column from the EMP table
ResultSet rset = stmt.executeQuery ( "select * from Test ");
// Iterate through the result and print the employee names
while (rset.next ())
System.out.println (rset.getString (1));
}
}
其中
String url = "jdbc:oracle:thin:@172.28.31.85:1521:YIKATONG ";
String userName = "scott ";
String password = "tiger ";
URL中的IP是不是本机地址?用户名和密码是连接数据库的密码还是连接OracleManagementServer的用户名密码
[解决办法]
String url = "jdbc:oracle:thin:@172.28.31.85:1521:YIKATONG ";
172.28.31.85：主机名－－如果是本地可用localhost
YIKATONG：服务（SID）
String userName = "scott ";
String password = "tiger ";
这是pl/sql登陆时的用户名和密码，不是oms的。
