Mybatis 中获得 connection

@Autowired
	private SqlSession sqlSession;

public Connection getConnection(){
		Connection conn = null;
		try {
			conn =  sqlSession.getConfiguration().getEnvironment().getDataSource().getConnection();
			logger.info("===This Connection isClosed ? "+conn.isClosed());
		} catch (Exception e) {
			e.printStackTrace();
		}
		return conn;
	}

 

 

String resource = "SqlMap.xml"; Reader reader = Resources.getResourceAsReader(resource); 
SqlMapClient sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader); 
Connection db = sqlMap.getDataSource().getConnection(); 
Statement st = db.createStatement(); 
ResultSet rs = st.executeQuery("show tables");
