如何从java.sql.Connection获取数据库URL？

Question

For given Connection instance how do I find out url that the Connection uses to connect the database ? Is it somewhere in Properties returned by Connection.getClientInfo() method?

If there you need me to provide clearer description all comments are welcome. Thank you

Answer 1

Connection has the getMetaData() to return DatabaseMetaData . DatabaseMetaData has the getURL() to return the URL for this DBMS.

Answer 2

I believe you can use the DatabaseMetaData object from the Connection and then get the URL. Try:

DatabaseMetaData dmd = connection.getMetaData();
String url = dmd.getURL();

Answer 3

Inside the Connection object, you have an object of type DatabaseMetaData, it contains a lot of information about the database.

Lucas de Oliveira gave you a good example of code.

And here is the documentation of the object : Interface DatabaseMetaData

Answer 4

connection.getClientInfo() has all the details related to connection. It returns a properties object. You can retrieve the value of "password" property to fetch the password that was used for the connection object.

Please let me know if this solves your problem.
