oracle 11g xe的locahost是什么？

Question

I'm doing a hibernate project for my final semester. I don't know what to enter here in my project for the hibernate configuration file jdbc:oracle:thin:@localhost: :XE .

Answer 1

localhost refers to your local machine. In the case you describe with Oracle, you need to specify the Oracle instance on your local machine. By default Oracle runs on port 1521 eg localhost:1521 .

To solve your problem, you should update your jdbc connection string to include the port.

Thus, your connection string should look something like the following:

 jdbc:oracle:thin:@localhost:1521:XE

Here is the Oracle JDBC API doc. It explains how to construct the connection url.

Answer 2

You are missing the port number. You have to see what port your database is using

jdbc:oracle:thin:@localhost:1525:XE

It is normally 1525
