springMVC环境搭建与逆向工程使用-学习笔记

spring环境准备

package com.java.springmvc.controller;

import java.util.ArrayList;
import java.util.Date;
import java.util.List;

import org.springframework.stereotype.Controller;
import org.springframework.web.HttpRequestHandler;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import pojo.Items;

@Controller
public class ItemController {

    @RequestMapping(value = "itemlist.action")
    public ModelAndView itemList(){

        // 创建页面需要显示的商品数据
        List list = new ArrayList();
        list.add(new Items(1, "1华为 荣耀8", 2399f, new Date(), "质量好！1"));
        list.add(new Items(2, "2华为 荣耀8", 2399f, new Date(), "质量好！2"));
        list.add(new Items(3, "3华为 荣耀8", 2399f, new Date(), "质量好！3"));
        list.add(new Items(4, "4华为 荣耀8", 2399f, new Date(), "质量好！4"));
        list.add(new Items(5, "5华为 荣耀8", 2399f, new Date(), "质量好！5"));
        list.add(new Items(6, "6华为 荣耀8", 2399f, new Date(), "质量好！6"));

        ModelAndView mav = new ModelAndView();
        //数据
        mav.addObject("itemList",list);
        mav.setViewName("itemList");
        return mav;
    }

}

环境配置

springmvc.xml

web.xml

    spri4
    
        index.html
        index.htm
        index.jsp
        default.html
        default.htm
        default.jsp
    

    
    
        springmvc
        org.springframework.web.servlet.DispatcherServlet
        
        
            contextConfigLocation
            classpath:springmvc.xml
        
    

    
        springmvc
        
        *.action
    

lib

jsp页面：

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt"  prefix="fmt"%>






 

查询条件：

商品列表：



    
商品名称
    
商品价格
    
生产日期
    
商品描述
    
操作


    
${item.name }
    
${item.price }
    

    
${item.detail }

    
修改

逆相工程

        boolean overwrite = true;
        //指定 逆向工程配置文件

        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);

        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
                callback, warnings);
        myBatisGenerator.generate(null);

    } 
    public static void main(String[] args) throws Exception {
        try {
