java.sql.SQLException:ORA-01005:给出了空密码；登录被拒绝 [英] java.sql.SQLException: ORA-01005: null password given; logon denied

问题描述

尝试连接数据库时出现以下异常:

I'm getting the follwing exception while trying to connect to a database:

java.sql.SQLException: ORA-01005: null password given; logon denied
        at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:450)
        at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:392)

        at com.alting.med.EventGenerator.exportData(EventGenerator.java:220)
        at com.alting.med.Main.main(Main.java:252)

此处是用于获得连接的方法:

here the method used to get the connection:

private Connection getConnection(String url, String driverClass, String user, String password) throws ManagerDBException 
{
    try
    {
        Class.forName(driverClass);
    } catch (ClassNotFoundException e) {
        throw new ManagerDBException(e.getMessage());
    }

    try
    {
      this.connection = DriverManager.getConnection(url, user, password);
    }
    catch (SQLException e)
    {
      throw new ManagerDBException(e.getMessage());
    }
    return this.connection;
}

但是即使对参数(URL，密码..)进行了硬编码，我仍然会遇到异常.

But even when the params (url, password..) are hardcoded, I still get the exception.

您能告诉我如何解决此问题吗? 谢谢

Could you tell me how to fix this problem ? thanks

推荐答案

看来问题是从Java启动命令行链接到"-Djava.endorsed.dirs"参数的.

it appears the problem is linked to the "-Djava.endorsed.dirs" parameter from the java startup command line.

通过删除这一部分，一切顺利.

By removing this one, everything goes well.
