the password expiration policy, including manual expira- tion, global-level automatic expiration, and account-level automatic expiration. After this policy is enabled, you must change your passwords periodically PlayerRepository extends JpaRepository { } Then, you can use @Autowired for automatic dependency injection in any class that requires the PlayerRepository. This enables you to directly multi-parameter and multi-field EOF in the prepare mode in the original JDBC, and adds features such as automatic TiCDC snapshot maintenance and the SM3 authentication plugin.
