SSM简易项目（增删改查）

本项目是一个Spring+SpringMVC+Mybatis+MySQL的一个小项目，项目只有简单的增删改查。

前端用了JQuery和Boostrap（其实也没用啥）。

纯粹是为了练习一下框架整合。

版本：Spring（4.3.6）、SpringMVC（4.3.6）、Mybatis（3.4.2）、MySQL（5.7.0）

虽然界面是食堂管理系统，但是，这都不是关键。。毕竟想改成啥就是啥。

开发环境：Eclipse+Tomcat8.5

FoodDao.java

package cn.lt.core.dao;
import java.util.List;

import org.apache.ibatis.annotations.Param;

import cn.lt.core.po.Food;

 * 用户DAO层接口
 */
public interface FoodDao {

	 * 通过账号和密码查询用户
	 */

	public List<Food> findAllFood();

	public void delFood(int id);
	
	public Food findFoodById(int id);
	
	public int updateFood(Food food);

	public Food findFoodByName(@Param("name")String name);
}

FoodDao.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" 
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >

5、Service

FoodService.java

package cn.lt.core.service;
import java.util.List;

import cn.lt.core.po.Food;

public interface FoodService {
	
	public List<Food> findAllFood();

	public boolean addFood(Food food);

	public void delFood(int id);
	
	public Food findFoodById(int id);
	
	public boolean updateFood(Food food);

	public Food findFoodByName(String name);
}

FoodServiceImpl.java

package cn.lt.core.service.impl;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import cn.lt.core.dao.FoodDao;
import cn.lt.core.po.Food;
import cn.lt.core.service.FoodService;
/**
 * 用户Service接口实现类
 */
@Service("foodService")
@Transactional
public class FoodServiceImpl implements FoodService {
	@Autowired
	private FoodDao foodDao;

	@Override
	public boolean addFood(Food food) {
		return this.foodDao.addFood(food)>0 ? true:false;
	}


	@Override
	public List<Food> findAllFood() {
		return this.foodDao.findAllFood();
	}


	@Override
	public void delFood(int id) {

	}


	@Override
	public Food findFoodByName(String name) {
		return this.foodDao.findFoodByName(name);
	}
	

}

6、Controller

FoodController.java

package cn.lt.core.web.controller;
