在vue2中使用cesium

我最经的项目中要使用cesium,cesium使用起来倒是简单原生的话直接复制就可以用了,但是在vue上就有点麻烦了。

VUE_CESIUM

因为我的情况不太一样,我的项目是用的vue2.6和vue-cil2建立的,现在网上的插件和教程多半都是新的,不太能通用。然后如果自己手动配置cesiumjs的话极其麻烦,要在webpack配置,本人水平不够。cesium版本间的区别还挺大的,后来我发现了一个我可以用的插件了就是VUE CESIUM。这个插件是有2.x和3.x版本的2.x就是vue2版本,其实我用这个插件就是不想自己配置cesium,导入这个就可以直接用了,你甚至可以直接写原生,不用他的组件。

注意:如果要用的话使用2.8版本的前面的版本bug比较多
