JDBC uses database transactions and jdbc database transactions

JDBC uses database transactions and jdbc database transactions

How does a java program use jdbc to define a transaction?

Set connection to not automatically submit
Change to manual submission;
Write the operation database in trycatch.
Throw an exception
Connection rollback;
This is a practice.

Private Connection conn = null;
Try {
Conn. setAutoCommit (false );
Conn. commit ();
Conn. close ();
} Catch (Exception e ){
Conn. rollback ();
}

Commit and roll back database transactions in jdbc

First, a database connection exception may be caused by JDBC connection or driver issues.
Second, the database is not found.
Third, the spelling of database fields is incorrect.
Fourth, SQL statement Error
Fifth, no. Haha. This is a problem I encountered in the last two days... It's all here ..
