# 1/23 JSP 觀念

###### tags: `JSP`
# 5-146.147 Bean Property值的轉換規則
# 5-148 設定JavaBeans Component Properties
Java大小寫有差別
"*"萬用字元
3.一定要是request參數名稱
# 5-149 Bean的共用
沒指定預設，會從page開始找
(參考127)
# 5-150 Conditional Bean的產生
(SharedCounts1.jsp 2 .3)
(AccessCountBean.java)
沒有useBean則需要產生，中間夾的那個敘述才會執行
大家共用計數器
(參考138.139)
# 5-151 JavaBean class的範例
Bean要在Package裡面
(參考125)
# 5-153.154 大綱
# 5-155 Jsp Architecture Models
# 5-156.157 Model 1 .2
身分權限Controller->jsp
jsp改漂亮就好
(參考servlet4-15)(B=JavaBean,S=Servlet,J=JSP)
# 5-158 MVA Demo(範例一)
(RegisterServlet.java)
(StudentBean.java)
(Thanks.jsp)
(DisplayStudent.jsp)
(StudentDAO.java)
(RegisterForm.jsp)(xml)
``

建構子
# 5-159 建立jwstudent table
(crestudent4sqlsvr.sql)
# 5-160 MVC EBookShop with Servlets,JSPs,and JavaBeans Deployed in Tomcat(範例二)
# 5-161 MVC+Shopping Cart(購物車)--Ebookshop
# 5-162 建立books table
(ebookshop4sqlsvr.sql)
# 5-163.164 JSP with Connection Pooling
(queryTest.jsp)
# 5-165 Servlet with Connection Pooling
(MySQLTestServlet.jsp)
# 5-166 Model:Book Database
(BookDB.java)
沒有建構子 符合沒有參數的建構子
# 5-167 CartItem.java
(CartItem.java)
[bookid]用bookid就能查
(參考161)
# 5-168 Controller
(ControllerServlet.java)
list轉換成Bean 陣列型態
從第0比 開始轉成一筆一筆陣列型態 toArray
