悠悠 2022-05-30 00:09 201阅读 0赞

1、Eclipse新建Dynamic Web Project项目：

（1） 将下载好的spring mybatis  及其整合包拷贝到WebContent----------WEB-INF---------lib目录下面，如下图所示：

jar下载地址：http://download.csdn.net/download/fengchengwu2012/10262888

（2）在上图的src文件上创建配置文件

创建spring的配置文件applicationContext.xml

创建mybatis的核心配置文件SqlMapConfig.xml

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

    	</typeAliases>
    
    
    
    	
    </configuration>

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>

创建键值对存储文件db.propeties,其中数据库的名称和密码换成需要连接的数据库

jdbc.driver=com.mysql.jdbc.Driver
    jdbc.url=jdbc:mysql://localhost/ssh_db
    jdbc.username=root
    jdbc.password=999999

创建log4j的配置文件log4j.properties

### \u8BBE\u7F6E###
    log4j.rootLogger = info,stdout
    
    ### \u8F93\u51FA\u4FE1\u606F\u5230\u63A7\u5236\u62AC ###

创建pojo实体类，并在mapper文件下写实体类所对应的mybatis映射文件

![70 1][]

实体类：

package cn.fcw.pojo;
    
    import java.io.Serializable;
    
    import javax.validation.constraints.Size;
    
    import org.codehaus.jackson.map.annotate.JsonSerialize;
    import org.codehaus.jackson.map.annotate.JsonSerialize.Inclusion;
    import org.springframework.lang.NonNull;
    
    import com.sun.istack.internal.NotNull;
    
    public class GoodsBean implements Serializable {
    	private  int      gid;
    	private  String   goods_img;
    	@Size(min=2,max=4,message="{goods.goods_name.length}")
    	private  String   goods_name;
    	private  String   goods_desc;
    	private  double   goods_price;
    	public int getGid() {
    		return gid;
    	}
    	public void setGid(int gid) {
    		this.gid = gid;
    	}
    	public String getGoods_img() {
    		return goods_img;
    	}
    	public void setGoods_img(String goods_img) {
    		this.goods_img = goods_img;
    	}
    	public String getGoods_name() {
    		return goods_name;
    	}
    	public void setGoods_name(String goods_name) {
    		this.goods_name = goods_name;
    	}
    	public String getGoods_desc() {
    		return goods_desc;
    	}
    	public void setGoods_desc(String goods_desc) {
    		this.goods_desc = goods_desc;
    	}
    	public double getGoods_price() {
    		return goods_price;
    	}
    	public void setGoods_price(double goods_price) {
    		this.goods_price = goods_price;
    	}
    	@Override
    	public String toString() {
    		return "GoodsBean [gid=" + gid + ", goods_img=" + goods_img + ", goods_name=" + goods_name + ", goods_desc="
    				+ goods_desc + ", goods_price=" + goods_price + "]";
    	}
    	
    
    }

GoodMpper.java

public interface GoodsMapper {
    	public List<GoodsBean> findAllGoods() throws Exception;
    	public List<GoodsBean> findGoodsByOrderNo(String  no) throws Exception;
    	public GoodsBean findGoodsById(int  goods_id)  throws Exception;
    	public  void updateGoodsByPojo(GoodsCustom  goodsCustom)  throws Exception;
    }

GoodsMapper.xml  映射文件中的sql便签的id必须和GoodsMpper.java里面的方法名一致

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE mapper  
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"  
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd">  
     <mapper  namespace="cn.fcw.mapper.GoodsMapper">  
         
         
       
       <select id="findAllGoods" resultType="cn.fcw.pojo.GoodsBean">
           select  *  from t_goods
           
       </select>
       
       <select id="findGoodsByOrderNo" parameterType="java.lang.String" resultType="cn.fcw.pojo.GoodsBean">
        select t_goods_order.g_id,t_goods.*  from t_goods_order inner join t_goods on t_goods_order.g_id=t_goods.gid and t_goods_order.order_no= #{value}
       </select>
       
        <select id="findGoodsById"  parameterType="java.lang.Integer" resultType="cn.fcw.pojo.GoodsBean">
           select *  from t_goods where gid= #{value}
       </select>
       
        <update id="updateGoodsByPojo"  parameterType="goodsCustom">
            
            update t_goods gd set gd.goods_name=#{goods_name},gd.goods_img=#{goods_img},gd.goods_price=#{goods_price},gd.goods_desc=#{goods_desc} where gd.gid=#{gid}
            
        </update>
    
    </mapper>

(3）创建service和controller

service层：

GoodsListService.java

public interface GoodsListService {
        public List<GoodsBean> findAllGoods() throws Exception;
        public List<GoodsBean> findGoodsByOrderNo(String vo) throws Exception;
        public GoodsCustom findGoodsById(Integer  goods_id)  throws Exception;
        public  void updateGoodsById(int  goods_id,GoodsCustom  goodsCustom)  throws Exception;
    }

GoodsListServiceImpl.java

@Service("goodsListService")
    @Transactional
    public class GoodsListServiceImpl  implements  GoodsListService{
    	@Autowired
    	@Qualifier("goodsMapper")
    	private GoodsMapper  goodsMapper;
    	@Override
    	public List<GoodsBean> findGoodsByOrderNo(String vo) throws Exception {
    		return  goodsMapper.findGoodsByOrderNo(vo);
    	}
    	
    	@Override
    	public  GoodsCustom findGoodsById(Integer goods_id) throws Exception {
    
    		GoodsBean goodsBean = goodsMapper.findGoodsById(goods_id);
    		GoodsCustom  goodsCustom=new GoodsCustom();
    		BeanUtils.copyProperties(goodsBean, goodsCustom);
    		return goodsCustom;
    	}
    
    	@Override
    	public void updateGoodsById(int goods_id, GoodsCustom goodsCustom) throws Exception {
    	      goodsCustom.setGid(goods_id);
    	      goodsMapper.updateGoodsByPojo(goodsCustom);
    	}
    
    	@Override
    	public List<GoodsBean> findAllGoods() throws Exception {
    		return goodsMapper.findAllGoods();
    	}
    }

controller层：

@Controller
    @RequestMapping("/goods")
    public class GetGoodsController {
    	
    	@Autowired
    	private  GoodsListService  goodsListService;
    	
    	@RequestMapping(value="/getAllGoods",method={RequestMethod.GET})
    	public String  findAllGoods(Model  model) {
    		List<GoodsBean> goods=null;
    		
    		try {
    			goods=goodsListService.findAllGoods();
    			model.addAttribute("list",goods);
    		} catch (Exception e) {
    		
    			e.printStackTrace();
    		}
    		
    		return "allGoodsList";
    		
    	}
    	
    	
    	@RequestMapping(value="/getAllGoodsList",method={RequestMethod.GET})
    	@ResponseBody
    	public String  findAllGoodsList() {
    		 List<GoodsBean> goods=null;
    		 Map<String, Object>  map=new HashMap<String, Object>();
    		
    		 ObjectMapper mapper = new ObjectMapper();
    		 String  res=null;
    		try {
    			goods=goodsListService.findAllGoods();
    			map.put("code",200 );
    			map.put("data", goods);
    			map.put("msg", "success");
    			
    	        JsonData jsonData=new JsonData();
    	        jsonData.setCode(200);

    	        jsonData.setMsg("success");
    	        res= mapper.writeValueAsString(jsonData);

    	@RequestMapping("/getGoodsList")
    	public ModelAndView   getList() {

    		}
    		
    		ModelAndView  modelAndView=new 	ModelAndView();
    	    modelAndView.addObject("list", goods);
    	    modelAndView.setViewName("goodsList");
    		return modelAndView;
    	}
    	
    	
    	@RequestMapping(value="/jumpDetail")
    	public String jumpGoodDetail() {
