java web 站点头像上传处理 (springmvc +bootstrap+cropper)
制作头像上传。请依据您的实际需求。改动代码，不全然正确。仅供參考！
前端页面设计使用bootstrap ，头像预览和剪裁工具使用cropper
后台使用springmvc。
如今来看前端的页面设计
前端页面设计，自然须要bootstrap 、jqury 和cropper ，这能够自行去网上百度查找

如今前端的基本完毕。如今最重要的来了。就是后台java 处理了。在网上找过非常多，发现没有，关于springmvc的，上面的内容基本上在网上找到，以下的springmvc的。关于图像处理的。就是我个人做的。好像网上有直接在前端进行剪裁的，可惜我不会啊，所以我还是老老实实的在后台处理了。
