JDBC连接Oracle报错ORA-12505

时间：2017-12-19

异常：ORA-12505, TNS: listener does not currently know of SID given in connect descriptor

情景：写了一个Strust2 Demo连接Oracle数据库运行时报错，对应所用Jar为：ojdbc6.jar

原因：jdbc连接URL填写错误，

原本的写法是：jdbc:oracle:thin:@172.31.60.51:1521:SHRMS;

正确的写法是：

jdbc:oracle:thin:@(description=(address=(protocol=tcp)(port=1521)(host=172.31.60.51)(PORT = 1521))(connect_data=(SERVER = DEDICATED)(service_name=SHRMS)))

解决办法：参考这里

连接代码：

package com.qiu.util;


import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;


public class TestOracle {
	public void testOracle()
	{
	    Connection con = null;// 创建一个数据库连接
	    PreparedStatement pre = null;// 创建预编译语句对象，一般都是用这个而不用Statement
	    ResultSet result = null;// 创建一个结果集对象
	    try
	    {
	        Class.forName("oracle.jdbc.driver.OracleDriver");
	        System.out.println("开始尝试连接数据库！");
	        String url = "jdbc:oracle:thin:@(description=(address=(protocol=tcp)(port=1521)(host=172.31.60.51)(PORT = 1521))(connect_data=(SERVER = DEDICATED)(service_name=SHRMS)))";
	        //String url = "jdbc:oracle:thin:@172.31.60.51:1521:SHRMS;";
	        String user = "admin";
	        String password = "password";
	        con = DriverManager.getConnection(url, user, password);
	        System.out.println("连接成功！");
	    }catch (Exception e){
	        e.printStackTrace();
	    } finally{
	        try{
	            if (result != null)
	                result.close();
	            if (pre != null)
	                pre.close();
	            if (con != null)
	                con.close();
	            System.out.println("数据库连接已关闭！");
	        }catch (Exception e){
	            e.printStackTrace();
	        }
	    }
	}
}
