css可以实现：
transform 属性向元素应用 2D 或 3D 转换。该属性允许我们对元素进行旋转、缩放、移动或倾斜。
代码如下：可以复制运行下试试：

<html>
<head>

<style>

body {
background:#ddd;
}
.keleyi {
width: 220px;
height: 220px;
margin: 0 auto;
background: no-repeat url("http://keleyi.com/image/a/q5l1xnmf.jpg") left top;
-webkit-background-size: 220px 220px;
-moz-background-size: 220px 220px;
background-size: 220px 220px;
-webkit-border-radius: 110px;
border-radius: 110px;
-webkit-transition: -webkit-transform 2s ease-out;
-moz-transition: -moz-transform 2s ease-out;
-o-transition: -o-transform 2s ease-out;
-ms-transition: -ms-transform 2s ease-out;
}
.keleyi:hover {
-webkit-transform: rotateZ(360deg);
-moz-transform: rotateZ(360deg);
-o-transform: rotateZ(360deg);
-ms-transform: rotateZ(360deg);
transform: rotateZ(360deg);
}
</style>
</head>
<body>
<div class="keleyi"></div>

</body>
