Java源代码如下：publicListgetAllMsgList(){ListmsgList=newArrayList();DBConnectiondb=newDBConnection();Connectionconn=db.getConn();Stringsql="select*frommsg...

Java 源代码如下：

public List getAllMsgList() { List msgList = new ArrayList(); DBConnection db = new DBConnection(); Connection conn = db.getConn(); String sql = "select * from msg"; try { Statement pstmt = conn.createStatement(); ResultSet rs = pstmt.executeQuery(sql); if (rs.next()) { int id = rs.getInt(1); String content = rs.getString(2); String author = rs.getString(3); String publishiTime = rs.getString(4); Msg msg = new Msg(id, content, author, publishiTime); msgList.add(msg); } rs.close(); pstmt.close(); conn.close(); } catch (SQLException e) { e.printStackTrace(); } return msgList; }

main函数：

IMsgDAO dao = new MsgDAOMysqlImpl(); List msgList = dao.getAllMsgList();

for (Msg item : msgList) { System.out.println("id=" + item.getId() + "\tautor=" + item.getAutor() + "\tcontent=" + item.getContent() + "\tpublishiTime=" + item.getPublishiTime()); }

数据库内容：

输出显示：

id=1 autor=22 content=你是谁啊 publishiTime=20130717001624
