springMvc - 02 項目創建

1、Idea項目創建

1、在磁盤上創建SpringMvc目錄

2、通過File->open打開該目錄

3、在目錄內創建模塊

單擊Next

4、給項目增加WebApp目錄

設置SDK

添加Web

選擇添加的項目：

編輯路徑：增加src\main，web修改成webSite

下方的Resource Directories相同的修改

點擊Apply即可。

處理之後的目錄結構會增加webSite目錄，注意圖標形態。

5、配置artifact打包方式

選擇項目模塊，並進行配置

2、Idea配置Tomcat

1、打開配置窗口

2、添加Tomcat

3、配置Tomcat

部署到項目的Artifice

5、配置Tomcat熱部署

一定要通過Debug模式運行

2、相關文件配置

2.1、pom.xml

3、測試例子

3.1、創建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;

/*測試控制器*/
public class TestController implements Controller {
    @Override
    public ModelAndView handleRequest(javax.servlet.http.HttpServletRequest httpServletRequest, javax.servlet.http.HttpServletResponse httpServletResponse) throws Exception {

        System.out.println("執行Controller");
        List<ex_Order> orderList = new ArrayList<ex_Order>();
        ex_Order item = new ex_Order();
        item.setOrderId("T005");
        item.setOrderDate(null);
        orderList.add(item);

        //創建返回的視圖對象
        ModelAndView viewResult = new ModelAndView();
        //添加返回的數據
        viewResult.addObject("orderList",orderList);
        //設定所用視圖 - 自動匹配到/WEB-INF/jsp/test/index.jsp
        viewResult.setViewName("/test/index");
        return  viewResult;
    }
}
