09.事务管理、整合jpa

事务管理

• spring-boot-starter-jdbc会自动默认注入DataSourceTransactionManager
• spring-boot-starter-data-jpa会自动默认注入JpaTransactionManager

@Service
@Transactional
public class UseDao {
    @Autowired
    private JdbcTemplate jdbcTemplate;

    public int updatePhoneByIDOne(String phone,Long id){
        String sql = "update ADMIN_USER set phone=? where ID = ?";
        int i = jdbcTemplate.update(sql,new Object[]{phone,id});
        int a = 1/0;
        return i;
    }
}
