I'd suggest to use the jQuery Star Rating pluginfor this. Check the demo pagehow it all look like. The JSP/HTML basically look like this (you only need to put the necessary JS/CSS/image files in the public webcontent). The magic is done by giving the radio buttons the class name star.
我建议为此使用jQuery Star Rating 插件。检查演示页面它的样子。JSP/HTML 基本上是这样的（你只需要把必要的 JS/CSS/图像文件放在公共网页内容中）。魔法是通过给单选按钮类名来完成的star。
<!DOCTYPE html>
<html lang="en">
<head>
<title>Star rating demo</title>
<link rel="stylesheet" href="jquery.rating.css">
<script src="jquery.js"></script>
<script src="jquery.rating.js"></script>
</head>
<body>
<form>
<input type="radio" name="rating" value="1" class="star">
<input type="radio" name="rating" value="2" class="star">
<input type="radio" name="rating" value="3" class="star">
<input type="radio" name="rating" value="4" class="star">
<input type="radio" name="rating" value="5" class="star">
</form>
</body>
</html>
In the server side you just use HttpServletRequest#getParameter()to obtain the rating value.
在服务器端，您只是HttpServletRequest#getParameter()用来获取评级值。
String rating = request.getParameter("rating");
// ...
With the above example, it'll return 1, 2, 3, 4 or 5.
在上面的例子中，它会返回 1、2、3、4 或 5。
