JDBC连接ORACLE的三种URL格式

格式一: Oracle JDBC Thin using an SID: 
jdbc:oracle:thin:@host:port:SID 
Example: jdbc:oracle:thin:@localhost:1521:orcl 
这种格式是最简单也是用得最多的 

import java.sql.*;

public class TestOrclConnect {

    public static void main(String[] args) {
        ResultSet rs = null;
        Statement stmt = null;
        Connection conn = null;
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
            String dbURL = "jdbc:oracle:thin:@localhost:1521:orcl";
            conn = DriverManager.getConnection(dbURL, "admin2", "123");
            System.out.println("连接成功");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            try {
                if (rs != null) {
                    rs.close();
                    rs = null;
                }
                if (stmt != null) {
                    stmt.close();
                    stmt = null;
                }
                if (conn != null) {
                    conn.close();
                    conn = null;
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}

格式二: Oracle JDBC Thin using a ServiceName: 
jdbc:oracle:thin:@//host:port/service_name 
Example:jdbc:oracle:thin:@//localhost:1521/orcl.city.com 
 

import java.sql.*;

public class TestOrclConnect {

    public static void main(String[] args) {
        ResultSet rs = null;
        Statement stmt = null;
        Connection conn = null;
        try {
            Class.forName("oracle.jdbc.driver.OracleDriver");
            String dbURL = "jdbc:oracle:thin:@//localhost:1521/orcl.city.com";
            conn = DriverManager.getConnection(dbURL, "admin2", "123");
            System.out.println("连接成功");
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            try {
                if (rs != null) {
                    rs.close();
                    rs = null;
                }
                if (stmt != null) {
                    stmt.close();
                    stmt = null;
                }
                if (conn != null) {
                    conn.close();
                    conn = null;
                }
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }
}

一般plsql中的ora数据库配置文件中可以。
