3、测试例子
3.1、创建Controller
package rui.web;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import rui.db.Dao.ex_OrderDao;
import rui.db.Model.ex_Order;
import java.util.ArrayList;
import java.util.List;
/*测试控制器*/
public class TestController implements Controller {
@Override
public ModelAndView handleRequest(javax.servlet.http.HttpServletRequest httpServletRequest, javax.servlet.http.HttpServletResponse httpServletResponse) throws Exception {
System.out.println("执行Controller");
List orderList = new ArrayList();
ex_Order item = new ex_Order();
item.setOrderId("T005");
item.setOrderDate(null);
orderList.add(item);
//创建返回的视图对象
ModelAndView viewResult = new ModelAndView();
//添加返回的数据
viewResult.addObject("orderList",orderList);
//设定所用视图 - 自动匹配到/WEB-INF/jsp/test/index.jsp
viewResult.setViewName("/test/index");
return viewResult;
}
}
