Answer 1

我想你的图像是一个字节数组。因此，您应该将图像作为 base64 字符串添加到速度上下文中。

velocityContext.put("image", Base64.encode(requestQuotationPojo.getImage()));
并在您的模板文件中使用此 img 标签。

<img src="data:image/jpg;base64,${image}" border="0" width="50" height="50"/>

Answer 2

${websitename} : 写下您的网站名称。

${rfqDetails.image} : 你的图片路径。

Like Your image url: http://test.com/folder/abc.png

#set($imgsrc="http://${websitename}/${rfqDetails.image})

 <img width="50" src="$imgsrc" border="0" height="50" alt="test">
