SpringMVC2 1 Starter Program

1 Starter Programs 1 . 1 Requirements for Product List query 1 . 2 The jar package required uses SPRING3. 2.0(with SPRINGWEBMVC module)

1.1The processor mapper is configured in Springmvc.xml: beannameurlhandlermapping: Matches the spring container bean based on the request URL (xxxx.action) Name to find the corresponding bean (program-written handler)<!--lookup based on the Bean's name handler the URL of the action in the bean's name-<Beanclass="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>All processor mappers implement the Handlermapping interface. 1. 2 Processor Adapter in Springmvc.xml configuration:<beanclass="Org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"/>all adapters are implemented with the Handleradapter interface. Program writing handler (similar to action) is written according to the requirements of the adapter. Simplecontrollerhandleradapter Adapter Requirements: You know through the Supports method which interface handler must implement:

1 . 1Handler authoring requires the Controller interface to be implemented:

ItemController1: Public Abstract classItemController1 implements Controller {@Override PublicModelandview HandleRequest (httpservletrequest request, httpservletresponse response) throws Exception { //use static data to display a list of commodity information on a JSP page//Product ListList<items> itemslist =NewArraylist<items>(); Items Items_1=NewItems (); Items_1.setname ("Lenovo Notebook");        Items_1.setprice (6000F); Items_1.setcreatetime (NewDate ()); Items_1.setdetail ("ThinkPad T430 Lenovo notebook computer! "); Items items_2=NewItems (); Items_2.setname ("Apple Phone");        Items_2.setprice (5000F); Items_2.setdetail ("iphone6 Apple Phone! ");        Itemslist.add (Items_1);        Itemslist.add (items_2); Modelandview Modelandview=NewModelandview (); //populating data into the request//Request.setattribute ("Itemslist", itemslist);Modelandview.addobject ("itemslist", itemslist); //specify a forwarded JSP pageModelandview.setviewname ("/web-inf/jsp/itemslist.jsp"); returnModelandview; }}1. 1 configuration handler in Springmvc.xml configuration handler by spring management handler. <!--configuration handler because the Beannameurlhandlermapping processing mapper is used, name is configured as a URL--<bean id="ItemController1"Name="/itemlist.action"        class="Cn.itcast.springmvc.first.ItemController1"/>1. 2 Configure the View resolver to configure view resolution to parse the JSP view:<!--Configure the view resolver to add JSTL packages to Classpath-<!--viewresolver--<Beanclass="Org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix"Value="/web-inf/jsp/"/> <property name="suffix"Value=". JSP"/> </bean>1. 3 Project Deployment access: http://localhost:8080/springfrist1110/itemlist.action
