關於 Ant ,[object Object],[object Object],[object Object],[object Object],[object Object]

問題在設計 ,[object Object],[object Object]

劃分出系統架構中的各層 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

何謂 Facade ,[object Object],[object Object]

你需要的只是 Code Gen 嗎？ ,[object Object],[object Object],[object Object],[object Object]

有些 Web Application 的問題在於 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],問題所在

LWDBA ,[object Object],[object Object],[object Object]

對資料庫存取的需求 ,[object Object],[object Object],[object Object],[object Object],[object Object]

資料庫的設定 ,[object Object],lwdb.pool.default.type=mysql lwdb.pool.default.driverClassName=org.gjt.mm.mysql.Driver lwdb.pool.default.driverURL=jdbc:mysql://localhost:3306/lwdba lwdb.pool.default.userName=root lwdb.pool.default.password=root lwdb.pool.default.maxConnectionCount=32 lwdb.pool.default.encoding=UTF-8 lwdb.pool.default.sqlFile=sql

LWDBA 對 SQL 的態度 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

SQL 操作－ DBRow (1/3) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

SQL 操作－ DBRow (2/3) ,[object Object],[object Object],[object Object],[object Object]

SQL 操作－ DBRow (3/3) DBRow dr = new DBRow("Customer", "seqNo"); dr.setColumn("name", name); dr.setColumn("phone", phone); dr.setColumn("address", address); System.out.println(dr.toInsertString());

SQL 操作－ SQLManager (1/4) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

SQL 操作－ SQLManager (2/4) ,[object Object],[object Object]

SQL 操作－ SQLManager (3/4) ,[object Object],[object Object],[object Object]

SQL 操作－ SQLManager (4/4) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

存取 Database － DBFacade ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

查詢結果－ QueryResult ,[object Object],[object Object],[object Object]

取得查詢結果 ,[object Object],[object Object],[object Object],[object Object],[object Object]

取得查詢結果－範例 StatisticsFacade facade = StatisticsFacade.getInstance(); ArrayList al = PPTVStatisticsFacade.listStatistics(n); <% for(int i=0;i<al.size();i++) { HashMap hm = (HashMap) al.get(i); %> <tr> <td><%=hm.get("seqNo")%></td> <td><%=hm.get("uid")%></td> <td><%=hm.get("remoteHost")%></td> <td><%=hm.get("type")%></td> <td><%=hm.get("createTime")%></td> </tr> <% } %>

基於 LWDBA 的設計 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

撰寫 Facade ,[object Object],[object Object]

使用 Façade 的優點 ,[object Object],[object Object],[object Object],[object Object],[object Object]
