java 连接oracle报错java.sql.SQLException: Listener refused the connection with the following error
代码为：
String driver="oracle.jdbc.driver.OracleDriver";
String url="jdbc:oracle:thin:@169.254.118.5:1521/orcl";
String user="scott";
String password="tiger";
try {
Class.forName(driver);
Connection conn=DriverManager.getConnection(url, user, password);//此处即为最后一行中所提的15行
System.out.println("成功得到链接");
conn.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
报错信息为：
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor
The Connection descriptor used by the client was:

String url="jdbc:oracle:thin:@169.254.118.5:1521/orcl";

take this
String url="jdbc:oracle:thin:@169.254.118.5:1521:orcl";
再问： 大师，好像还是不行呢，报错变成这样 了 java.sql.SQLException: Listener refused the connection with the following error: ORA-12505 了
再答：
public class ConnectionTest {

static Connection conn;
static Statement stm;
static ResultSet rs;
static String driver = "oracle.jdbc.driver.OracleDriver";
static String url = "jdbc:oracle:thin:@127.0.0.1:1521:orcl";

public static void main(String[] args) {
try {
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());

conn = DriverManager.getConnection(url, "scott",
"WaydeWang84293972");
stm = conn.createStatement();
//String sql = "create table test2(id NUMBER(6) not null)";
//ResultSet rs1 = stm.executeQuery(sql);
stm.executeUpdate("insert into test2 values(" + 3453 + ")");
stm.executeUpdate("insert into test2 values(" + 1234 + ")");
stm.executeUpdate("insert into test2 values(" + 2345 + ")");
stm.executeUpdate("insert into test2 values(" + 4567 + ")");
rs = stm.executeQuery("select * from test2");
while (rs.next()) {
System.out.println(rs.getInt("ID"));

}
conn.close();
} catch (SQLException e) {

e.printStackTrace();
}
}

}

你改成你的，如果还不可以，你就是oracle监听服务什么的出错了
再问： 依旧是12505，貌似监听真的出问题了…… 求大师支招……
