Element中的el-input-number+SpringBoot+mysql

1、编写模板

  
    
  
  
    
  
  
       
  
  
    保存  
  

2、前端发请求

  editGoods() {
            if (this.id == '' && this.id == null) {
                this.$message({
                    message: 'id不能为空',
                    type: 'error'
                })
                return;
            } else if (this.name == '' && this.name == null) {
                this.$message({
                    message: '名称不能为空',
                    type: 'error'
                })
                return;
            }
            this.$axios({
                method: 'post',
                url: 'http://localhost:8080/api/upload/editGoods',
                data: {
                    id: this.id,
                    name: this.name,
                    price: this.price

                }
            }).then((res) => {
                this.$message({
                    message: '修改成功',
                    type: 'success'
                })
            })
        }

3、后端返回数据

1.编写实体类

package com.example.goods_admin.entity;

public class Goods extends Page {
    private String id;
    private String name;
    private int price;
    private String imageUrl;
    private String status;

    public Goods() {
        super();
    }
    public Goods(int pageNum, int pageSize, String keyWord) {
        super(pageNum, pageSize, keyWord);
    }
    public Goods(int pageNum, int pageSize, String keyWord, String id, String name, int price, String imageUrl, String status) {
        super(pageNum, pageSize, keyWord);
        this.id = id;
        this.name = name;
        this.price = price;
        this.imageUrl = imageUrl;
        this.status = status;
    }


    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getPrice() {
        return price;
    }

    public void setPrice(int price) {
        this.price = price;
    }

    public String getImageUrl() {
        return imageUrl;
    }

    public void setImageUrl(String imageUrl) {
        this.imageUrl = imageUrl;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String status) {
        this.status = status;
    }
}

2.Controller类 

@RestController
@RequestMapping("/upload")
public class UploadFileController {

    @Autowired
    UploadFileService uploadFileService;

    //json传参
    @GetMapping("/editGoods")
    public Result editGoods(@RequestBody Goods goods) {
        return uploadFileService.editGoods(goods);
    }
}

 3、interface接口（Service层接口）

public interface UploadFileService {

    Result editGoods(Goods goods);
}

  4.Service（接口实现）

@Service
public class UploadFileServiceImpl implements UploadFileService {
    @Autowired
    UploadFileMapper uploadFileMapper;

     @Override
    public Result editGoods(Goods goods) {
        int count=uploadFileMapper.updateGoods(goods);
        if (count==1){
            return Result.succeed("删除成功");
        }else{
            return Result.failed("删除失败");
        }
    }

}

 5、interface接口（Mapper层接口）

public interface UploadFileMapper {

    int saveGoods(Goods goods);

}

6、xml(动态sql)

    
        
        
        
        
        

    
    
        INSERT INTO goods (
        
            id
        
        
            ,name
        
        
            ,price
        
        
            ,imageUrl
        
        
            ,status
        
        ) VALUES (
        
            #{id}
        
        
            ,#{name}
        
        
            ,#{price}
        
        
            ,#{imageUrl}
        
        
            ,#{status}
        
        )
    

7、效果
