写的测试代码如下:

public void test() {
Connection conn = null;
Statement stmt = null;
ResultSet rs = null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");

        String url = "jdbc:oracle:thin:@192.168.1.155:1521:orcl";
        String dbUsername = "test";
        String dbPassword = "test";

        conn = DriverManager.getConnection(url, dbUsername, dbPassword);
        System.out.println("正常");
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("异常");
    } finally {
        if (conn != null) {
            try {
                conn.close();
            } catch (SQLException e) {
                e.printStackTrace();
            }
        }
    }

}

用sqlDeverloper工具可以连接,但是写代码就不行,其他的电脑同样的开发工具和代码可以连接,求大神!!!!!

String url = "jdbc:oracle:thin:@192.168.1.155:1521:orcl";
改为
String url = "jdbc:oracle:thin:192.168.1.155:1521:orcl";

楼主问题解决了吗?我也遇到同样问题,win10家庭中文版,ojdbc6,eclipse代码连接数据库报 connection refuse,但是用plsql工具连接是没有问题的,把代码移到其它电脑上也是没问题的,困扰好几天了,是什么原因导致的呢?
