如何从db网页显示jpg？

Question

我有来自数据库(mysql)的表和显示数据.我用百里香.所有字段都可以,但sb.cover不显示jpg(我的数据库中的blob列).您是否有任何想法如何使用百里香叶将jpg放入网页？谢谢

<tr th:each="sb, poz : ${product}">
    <td th:text="${poz.count}">1</td>
    <td th:icon="${sb.cover}"></td>
    <td th:text="${sb.title}"></td>
    <td th:text="${sb.price}"></td>
    <td ><b><a th:href="@{/details}">DETAILS</a></b></td>
    <td ><b><a th:href="@{/cart}">ADD TO CART</a></b></td>
    </tr>

Answer 1

它对我有用:

<img class="info" th:attr="src=@{${image}}" />

其中'image'是base64图片:

image ="data:image/png; base64,R0lGODlhlgCWAMQAAPz .........

在Spring Java Controller中:

@RequestMapping(value = "/get_goods_detail", method = RequestMethod.GET)
public String getGoodsDetail(@RequestParam(value = "itemid") final int itemid,
                             ModelMap model) {
    // get image
    String image = "data:image/png;base64,R0lGODlhlgCWAMQAAPz8/N3d3eX.../big image

    model.addAttribute("image", image);
    return  "goods_detail";  // return name of html view with thymeleaf
}

我不确定这会对你有帮助......

<tr th:each="sb, poz : ${product}">
    <td th:text="${poz.count}">1</td>
   <td><img  th:attr="src=@{${sb.cover}} , title=#{background}, alt=#{background}" style="width: 150px; height: 150px;" /></td> 
    <td th:text="${sb.title}"></td>
    <td th:text="${sb.price}"></td>
    <td ><b><a th:href="@{/details}">DETAILS</a></b></td>
    <td ><b><a th:href="@{/cart}">ADD TO CART</a></b></td>
    </tr>
