mybatis获取表信息，以及遍历ResultSet

@RunWith(SpringRunner.class)
@SpringBootTest
public class BravolinksCrmServerApplicationTests {

	@Autowired
	private SqlSessionFactory sqlSessionFactory;

	@Test
	public void contextLoads() throws SQLException {
		Connection conn = sqlSessionFactory.openSession().getConnection();
		DatabaseMetaData data = conn.getMetaData();
		ResultSet rs = data.getColumns(null,null,"PM_DUOCIDUIZHANG","%");
//		while (rs.next()){
//			//打印字段name信息
//			System.out.println(rs.getString("COLUMN_NAME"));
//		}

		//遍历resultset
		List<Map<String,Object>> list = new ArrayList<>();
		ResultSetMetaData rsmd = rs.getMetaData();
		int count = rsmd.getColumnCount();
		while (rs.next()) {
			Map rowData = new HashMap();//声明Map
			for (int i = 1; i <= count; i++) {
				System.out.println(rsmd.getColumnName(i)+"="+rs.getObject(i));
				rowData.put(rsmd.getColumnName(i), rs.getObject(i));//获取键名及值
			}
			list.add(rowData);
		}
		System.out.println("list = " + list.size());
