服务详情修改优化

ProductServiceImpl

product后端保存操作修改

    @Override
    public void update(Product product) {
        ProductDetail detail = product.getDetail();
        if(detail !=null){
            if(detail.getId() !=null){
                productDetailMapper.update(detail);
            }else{
                productDetailMapper.save(detail);
            }
        }

        productMapper.update(product);
    }

Product.vue

显示新增界面清除页面缓存

			//显示新增界面
			handleAdd: function () {
				this.fileList = [];//清楚页面缓存数据
				this.productFormVisible = true;//显示新增弹出框
				this.productForm = {
					id: null,
					name: '',
					resources: '',
					saleprice: 0,
					costprice: 0,
					detail:{
						id:null,
						intro:'',
						orderNotice:''
					}
				};
			},

使用步骤

见文档

测试

图片的访问方式

1.链接访问，
2.页面本地存储二进制字节码，base64加密，长度很长不好保存到数据库，

富文本集成fastDfs

修改页面本地存储为链接存储，步骤见文档
结果：

后台服务上下架（批量）

前端开始

页面加两个按钮，未选置灰，绑定事件，传id数组到后端，

<el-form-item>
	<el-button type="success" @click="onsale" :disabled="this.sels.length===0">上架</el-button>
</el-form-item>
<el-form-item>
	<el-button type="warning" @click="offsale" :disabled="this.sels.length===0">下架</el-button>
</el-form-item>

		sels: [],//列表选中行

		onsale(){
			var ids = this.sels.map(item => item.id);
			//获取选中的行
			if(!this.sels || this.sels.length  <1){
				this.$message({ message: '老铁，你不选中数据，臣妾上架不了啊....',type: 'error'});
				return;
			}
			this.$confirm('确认上架选中记录吗？', '温馨提示', {
				type: 'warning'
			}).then(() => {
				this.listLoading = true;
				this.$http.post('/product/onsale',ids).then((res) => {
					this.listLoading = false;
					if(res.data.success){
						this.$message({
							message: '上架成功',
							type: 'success'
						});
					}else{
						this.$message({
							message: res.data.message,
							type: 'error'
						});
					}
					this.getProducts();
				});
			}).catch(() => {

			});
		},
		offsale(){
			var ids = this.sels.map(item => item.id);
			//获取选中的行
			if(!this.sels || this.sels.length  <1){
				this.$message({ message: '老铁，你不选中数据，臣妾下架不了啊....',type: 'error'});
				return;
			}
			this.$confirm('确认下架选中记录吗？', '提示', {
				type: 'warning'
			}).then(() => {
				this.listLoading = true;
				this.$http.post('/product/offsale',ids).then((res) => {
					this.listLoading = false;
					if(res.data.success){
						this.$message({
							message: '下架成功',
							type: 'success'
						});
					}else{
						this.$message({
							message: res.data.message,
							type: 'error'
						});
					}
					this.getProducts();
				});
			}).catch(() => {

			});
		}

后端完成

ProductController

    /**
     * 批量上架
     */
    @PostMapping("/onsale")
    public AjaxResult onsale(@RequestBody List<Long> ids){
        try {
            productService.onOrOffSale(ids,1);//flag：0下架 1上架
            return AjaxResult.me();
        } catch (Exception e) {
            e.printStackTrace();
            return AjaxResult.me().setMessage("上架失败！"+e.getMessage());
        }
    }

    /**
     * 批量下架
     */
    @PostMapping("/offsale")
    public AjaxResult offsale(@RequestBody List<Long> ids){
        try {
            productService.onOrOffSale(ids,0);//flag：0下架 1上架
            return AjaxResult.me();
        } catch (Exception e) {
            e.printStackTrace();
            return AjaxResult.me().setMessage("下架失败！"+e.getMessage());
        }
    }

ProductServiceImpl

    @Override
    public void onOrOffSale(List<Long> ids, int flag) {
        //1.判断是上架还是下架
        Map<String,Object> map = new HashMap<>();
        map.put("ids", ids);
        if(flag == 1){
            //1.1 调整状态
            //1.2时间
            map.put("onSaleTime",new Date());
            productMapper.onSale(map);
        }else{
            //1.1 调整状态
            //1.2时间
            map.put("offSaleTime",new Date());
            productMapper.offSale(map);
        }
    }

ProductMapper

    <!--void onSale(Map<String, Object> map);-->
    <update id="onSale" >
        UPDATE t_product set state=1, onsaletime=#{onSaleTime} where id in
        <foreach collection="ids" item="id" open="(" close=")" separator=",">
            #{id}
        </foreach>
    </update>


    <!--void offSale(Map<String, Object> map);-->
    <update id="offSale" >
        UPDATE t_product set state=0, offsaletime=#{offSaleTime} where id in
        <foreach collection="ids" item="id" open="(" close=")" separator=",">
            #{id}
        </foreach>
    </update>

前台展示上架

前端开始

index修改栏目名称，拷贝search为product，修改引入路径，index支持跳转到product，product修改栏目名称并支持跳转到index，
拷贝success为adoutUs，修改引入路径，index支持跳转到adoutUs，adoutUs修改页面内容，

product引入vue和axios，用div包住body里的内容，写vue实例，

后端完成

ProductQuery

@Data
public class ProductQuery extends BaseQuery {
    //查询上下架的标识
    private Integer state;
}

ProductController

    /**
     * 前端主站使用的接口,只查询上架的
     */
    @PostMapping("/list")
    public PageList<Product> queryWebPage(@RequestBody ProductQuery productQuery){
        productQuery.setState(1);
        return productService.queryPage(productQuery);
    }

ProductMapper

    <!--Integer queryCount(ProductQuery productQuery);-->
    <select id="queryCount" parameterType="ProductQuery" resultType="integer">
        SELECT count(*) FROM t_product
        <include refid="whereSql"/>
    </select>

    <!--List<Product> queryData(ProductQuery productQuery)-->
    <select id="queryData" resultType="Product" parameterType="ProductQuery">
        SELECT * FROM t_product
        <include refid="whereSql"/>
        limit #{start},#{pageSize}
    </select>

    <!--Where条件-->
    <sql id="whereSql">
        <where>
            <if test="keyword != null and keyword != ''">
                AND name LIKE concat("%",#{keyword},"%")
            </if>
            <if test="state != null">
                AND state = #{state}
            </if>
        </where>
    </sql>

测试

注释掉拦截器，然后可以免登录用swagger测试

前端展示列表和图片

调整入参获取数据，遍历，按照规格渲染到页面

fastDfs传800×800可以自定转430×430，350×350，60×60，

服务高级查询

元素绑定

<div class="search-bar pr">
	<a name="index_none_header_sysc" href="#"></a>
	<form>
		<input id="searchInput" name="index_none_header_sysc" v-model="queryParams.keyword" type="text" placeholder="搜索" autocomplete="off">
		<input id="ai-topsearch" class="submit am-btn" @click="search" value="搜索" index="1" type="button">
	</form>
</div>

方法绑定

search() {
		this.queryParams.currentPage = 1;//定为到第一页
		this.getProducts();
	},

分页

页数计算与展示，不同页查询，左右箭头分页查询并限制不超过第一页和最后页，

<!--分页 -->
<ul class="am-pagination am-pagination-right">
	<!--class="am-disabled"-->
	<li>
		<a href="javascript:;" @click="handCurrentPage(queryParams.currentPage -1)">&laquo;</a>
	</li>

	<li v-for="page in countPage">
		<a href="javascript:;" @click="handCurrentPage(page)">
			{{page}}
		</a>
	</li>

	<li><a href="javascript:;" @click="handCurrentPage(queryParams.currentPage +1)">&raquo;</a></li>
</ul>

	computed: {
		countPage() {
			//向上取整
			return Math.ceil(this.pageList.total / this.queryParams.pageSize);
		}
	},

		handCurrentPage(page) {//动态分页
			if (page == 0) {
				this.queryParams.currentPage = 1;//定位到第一页
			} else if (page >= this.countPage) {
				this.queryParams.currentPage = this.countPage;//定位到最后页
			} else {
				this.queryParams.currentPage = page;//定位到所选页
			}
			this.getProducts();
		},

查看详情

跳转详情页

<li v-for="product in pageList.rows" @click="goDetail(product.id)">

	goDetail(productId) {//跳转到详情页
		//当前窗体打开
		//location.href = "http://localhost/productDetail.html?productId=" + productId;
		window.open("http://localhost/productDetail.html?productId=" + productId);
	},
