adminLTE 中使用 bootstrap-treeview 图标无法显示问题。

把bootstrap.css里面关于glyphicon的图标的全拿出来，再引入boosstarp的font如下图。然后自己把下面的css复制进去。这么点小问题搞了半天

 

@font-face {
    font-family:'Glyphicons Halflings';src:url(../fonts/glyphicons-halflings-regular.eot);src:url(../fonts/glyphicons-halflings-regulard41d.eot?#iefix) format('embedded-opentype'),url(../fonts/glyphicons-halflings-regular.woff2) format('woff2'),url(../fonts/glyphicons-halflings-regular.woff) format('woff'),url(../fonts/glyphicons-halflings-regular.ttf) format('truetype'),url(../fonts/glyphicons-halflings-regular.svg#glyphicons_halflingsregular) format('svg')
}
