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

Food.java

package cn.lt.core.po;

import java.io.Serializable;

public class Food implements Serializable{
	private static final long serialVersionUID = 1L;
//	主键
	private String id;
//	食品名称

	public String toString() {
		return "Food [id=" + id + ", name=" + name + ", price=" + price
				+ ", msg=" + msg + ", date=" + date + "]";
	}
	
}

4、Dao

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 int addFood(Food food);
	
	public List 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

    
    
	    insert into food(
	                     id,
	                     name,
	                     price,
	                     msg,
	                     date
	             )
	             values(#{id},
	                    #{name},
	                    #{price},
	                    #{msg},
	                    #{date}
	            )
	
     
	    select *
	    from food
    
    
    	delete from food where 
    		id=#{id}
    
    
      
        update food set 
        name=#{name},
        price=#{price},
        msg=#{msg},
        date=#{date} 
        where id=#{id}  
     
    
    
    select *
	    from food
	    where id=#{id}
    
    
    
    select *
	    FROM food
	    WHERE 
	    
		    
		   		name LIKE CONCAT('%', #{name, jdbcType=VARCHAR}, '%')
		    
		    
		    	1=0
		    
	  
	    
    
    
    

5、Service

FoodService.java

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

import cn.lt.core.po.Food;

public interface FoodService {
	
	public List 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 findAllFood() {
		return this.foodDao.findAllFood();
	}


	@Override
	public void delFood(int id) {
		this.foodDao.delFood(id);
	}


	@Override
	public Food findFoodById(int id) {
		return this.foodDao.findFoodById(id);
	}


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