我正在嘗試使用Oracle瘦驅(qū)動程序連接到Oracle 10 XE數(shù)據(jù)庫,但無法實現(xiàn)這一點.我什至在編譯過程中將驅(qū)動程序添加到我的類路徑中.

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.PreparedStatement;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.util.Properties;

public class Connectivity {

public static void main(String args[]) throws SQLException {

String url = "jdbc:oracle:thin:@localhost:1521:XE";

Properties props = new Properties();

props.setProperty("user", "SYSTEM");

props.setProperty("password", "iiita");

try {

Class.forName ("oracle.jdbc.driver.OracleDriver");

} catch (ClassNotFoundException e) {

System.out.println(e.getMessage());

}

Connection conn = DriverManager.getConnection(url,props);

String sql ="select sysdate as current_day from dual";

PreparedStatement preStatement = conn.prepareStatement(sql);

ResultSet result = preStatement.executeQuery();

while(result.next()){

System.out.println("Current Date from Oracle : " + result.getString("current_day"));

}

System.out.println("done");

}

}

該代碼在運行期間給出以下錯誤

Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@localhost:1521/XE

at java.sql.DriverManager.getConnection(DriverManager.java:644)

at java.sql.DriverManager.getConnection(DriverManager.java:202)

at Connectivity.main(Connectivity.java:16)

總結(jié)

以上是生活随笔為你收集整理的oracle瘦连接,java-无法使用jdbc瘦驱动程序连接到oracle数据...的全部內(nèi)容，希望文章能夠幫你解決所遇到的問題。
