Servlet accesses JavaBean and passes results to JSP

1. Create the package name first:

2. Creating entity Classes

Refer to the two-dimensional table, consider each field name, type

Create a class in the entity package with the following code:

 Public class House {    private  String ID;     Private String name;     Private String address;      Public String getId () {        return  ID;    }    ... .. // other

3. Establishing the Business Logic interface (Houseservice) and implementation (Houseserviceimpl)

Manager Write Interface: Public InterfaceHouseservice { PublicListgetallhouses ();} Brother Write implementation class: @Override PublicListgetallhouses () {List<House> houselist =NewArraylist(); //1 Bald-headed home forest, number 188th.//2 Bear Big House forest tree hole Phase 3 floorHouse H1 =NewHouse (); House H2=NewHouse (); H1.setid ("1"); H1.setname ("Great place to be."); H1.setaddress ("Forest No. 188th"); H2.setid ("2"); H2.setname ("The home of the Bear"); H2.setaddress ("3/F, forest Tree cave Phase One");        Houselist.add (H1);                Houselist.add (H2); returnhouselist; }

4. Create a (Servlet) controller, call the service Fetch DataSet list "Send the results to the JSP and jump to the past"

Create a new servlet:houseaction_showallhoses in the action package

4. Create a show.jsp to get the list from the Request object

Core code: Request.getattribute ("Houselist_label");

The rest of the code in the reference war package is the same as the previous example.
