• DbConfig

@ComponentScan("com.zsk.context.database")
@Configuration
@EnableTransactionManagement
public class DbConfig
{
    @Bean
    public DataSource dataSource() throws PropertyVetoException
    {
        ComboPooledDataSource dataSource = new ComboPooledDataSource();

}

• TestService

@Service
public class TestService
{
    @Autowired
    private TestDao testDao;

    @Transactional
    public void insert()
    {
        testDao.insert();
        int i = 10 / 0;
    }
}

• TestDao

@Repository
public class TestDao
{
    @Autowired
    private JdbcTemplate jdbcTemplate;

    public void insert()
    {
        String sql = "insert into `ttest`(id, status) values (66, 'close')";

        jdbcTemplate.execute(sql);
    }
