Spring使用webjar
注意事项
这玩意很简单，但是我们第一次搞就是搞不成功，为什么呢？因为我们都用的是idea或者eclipse编译。webjar只能在maven上才能打包，所以在使用时，记得maven-clean和maven-package！
先丢代码地址

再丢pom.xml

*
* webjars-locator 包的作用是处理WebJars，省略 webjar 的版本。
* 比如对于请求 http://localhost:8080/webjars/jquery/3.1.0/jquery.js省略版本号 3.2.1
* 直接使用http://localhost:8080/webjarslocator/jquery/jquery.js也可访问。
* 其实吧，webjar，webjarslocator都耗系统性能的！！！！！
