springMvc-02 项目创建
1、Idea项目创建
1、在磁盘上创建SpringMvc目录
2、通过File->open打开该目录
3、在目录内创建模块
单击Next
4、给项目增加WebApp目录
设置SDK
添加Web
选择添加的项目：
编辑路径：增加src\main，web修改成webSite
下方的Resource Directories相同的修改
点击Apply即可。
处理之后的目录结构会增加webSite目录，注意图标形态。
5、配置artifact打包方式
选择项目模块，并进行配置
2、Idea配置Tomcat
1、打开配置窗口
2、添加Tomcat
3、配置Tomcat
部署到项目的Artifice
5、配置Tomcat热部署
一定要通过Debug模式运行
2、相关文件配置
2.1、pom.xml

3、测试例子 - 老技术启用
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<ex_Order> orderList = new ArrayList<ex_Order>();
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;
}
}
3.2、创建视图
