java中连接Oracle数据源

java中连接Oracle数据源

本地不安装Oracle，用JAVA实现连接Oracle数据源：

数据库服务器：lips-db        端口： 1521         数据库名：JAVATECH
连接用户名：ebt        连接密码：ebt06        

import  java.sql. * ;

public   class  Welcome  {

    public static Connection getConnect() throws SQLException
    {
        DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
        Connection conn = DriverManager.getConnection(
            "jdbc:oracle:thin:@lips-db:1521:javatech", "ebt", "ebt06");
        return conn;
    }

    public static void main(String[] args) {
        try {
            Connection conn = Welcome.getConnect();
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery("select * from tbm_student");

            ResultSetMetaData rsmd = rs.getMetaData();
            for (int i = 1, n = rsmd.getColumnCount(); i <= n; i++)
            {
                System.out.print(rsmd.getColumnName(i));
                System.out.print(",");
                System.out.print(rsmd.getColumnClassName(i));
                System.out.print(",");
                System.out.print(rsmd.getColumnTypeName(i));
                System.out.println("");
            }
        }
        catch (SQLException se) {
            //
        }
        catch (Exception ex) {
            //
        }
    }
}

要成功运行，还需要引入classesxx.jar或者classesxx.zip：

<? xml version="1.0" encoding="UTF-8" ?>
< classpath >
     < classpathentry  kind ="src"  path ="" />
     < classpathentry  kind ="con"  path ="org.eclipse.jdt.launching.JRE_CONTAINER" />
     <classpathentry kind="lib" path="C:/oracle/ora92/jdbc/lib/classes12.jar"/>
     < classpathentry  kind ="output"  path ="" />
</ classpath >
