本文介绍了如何使用JdbcTemplate进行数据库操作，并通过DataSourceTransactionManager实现事务管理。重点展示了创建数据的具体步骤，包括设置数据源、创建数据操作服务以及执行SQL插入语句。

@Repository
public class SchemaRepository {

	public SchemaRepository() {
	}
	
	public void createData1(DataSource dataSource) throws SQLException {
		JdbcOperations jdbcOp = new JdbcTemplate(dataSource);
		String sql = "INSERT INTO `t1` (`t1_id`, `name`) VALUES (1, 't1name1')";	
		PreparedStatementCreatorFactory statementCreatorFactory = new PreparedStatementCreatorFactory(sql);
		statementCreatorFactory.setReturnGeneratedKeys(true);
		PreparedStatementCreator creator = statementCreatorFactory.newPreparedStatementCreator(new Object[] {});
		GeneratedKeyHolder keyHolder = new GeneratedKeyHolder();
		jdbcOp.update(creator, keyHolder);
	}
	
	public void createData2(DataSource dataSource) throws SQLException {
		JdbcOperations jdbcOp = new JdbcTemplate(dataSource);
		String sql = "INSERT INTO `t1` (`t1_id`, `name`) VALUES (1, 't1name2')";	
		PreparedStatementCreatorFactory statementCreatorFactory = new PreparedStatementCreatorFactory(sql);
		statementCreatorFactory.setReturnGeneratedKeys(true);
		PreparedStatementCreator creator = statementCreatorFactory.newPreparedStatementCreator(new Object[] {});
		GeneratedKeyHolder keyHolder = new GeneratedKeyHolder();
		jdbcOp.update(creator, keyHolder);
	}
}


@Service
public class SchemaService {

	private SchemaRepository schemaRepository;

	@Autowired
	public SchemaService(SchemaRepository schemaRepository) {
		this.schemaRepository = schemaRepository;
	}

	public void createData() throws SQLException {
		DataSource dataSource = new DriverManagerDataSource("jdbc:mysql://localhost:3306/abc", "root", "root");		
		DataSourceTransactionManager transactionManager = new DataSourceTransactionManager(dataSource);	
	    TransactionDefinition def = new DefaultTransactionDefinition();
	    TransactionStatus status = transactionManager.getTransaction(def);    
		try {
			schemaRepository.createData1(dataSource);
			schemaRepository.createData2(dataSource);
			
			transactionManager.commit(status);
		} catch (Exception e) {
			e.printStackTrace();
			transactionManager.rollback(status);
		}
	}
}
