springMvc02 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
