Class.forName(driverClass) not running

Question

System.out.println("======1======");
Class.forName(driverClass);
conn = DriverManager.getConnection("xxxx"," xxxx","xxxx");
System.out.println("======2======");

This paragraph is written in try catch without any error

The operation can print out ======1======
But in Class.forName(driverClass); the card owner
cannot print out======2=== ===

There are no errors in the whole process, but the conn cannot be obtained, and it is stuck in Class.forName
The jars are also under the classpath. If classnotfound, it will be caught by exception

Answer 1

Dear, is there something wrong with the compiler? Can you just use the java command to compile and execute it?

Answer 2

Are you sure you have something written in your catch?

Answer 3

Change

Class.forName(driverClass) to
Class.forName(driverClass).newInstance() and try it

Answer 4

It does not prove that it is stuck on the forName method. The probability of getting stuck on the getConnection method is much greater. This is to connect to the database.

Answer 5

YourClass.forName(driverClass); First, make sure you specify a specific path for the driverClass class you dynamically load;

Answer 6

driverclass needs to be enclosed in double quotes "driverclass"
