值得注意的是，/static/plugins/pdfjs-2.5.207-dist/web/viewer.html 应该是自己的文件路径。
http://localhost:8077/media/preview是我们Controller接口。
鼠标点击h1标签，就会跳转出我们的pdf文件预览页面.
以上完成了pdf的预览整合，到此就可结束了。
layer.open({
type: 2
,title: ‘pdf预览‘ //不显示标题栏
,closeBtn: false
,area: [‘90%‘,‘90%‘]
// ,shade: 0.8
// ,id: ‘LAY_layuipro‘ //设定一个id，防止重复弹出
,btn: [‘继续‘, ‘关闭‘]
,btnAlign: ‘c‘
,moveType: 1 //拖拽模式，0或者1
,moveOut: true
,closeBtn:1
,content: ‘http://localhost:8077/static/plugins/pdfjs-2.5.207-dist/web/viewer.html?file=http://localhost:8077/media/preview‘
,success: function(layero){
//点击按钮 do something
}
});
spring boot + pdf.js 实现pdf文件预览
