我是靠谱客的博主害羞酸奶，最近开发中收集的这篇文章主要介绍Spring使用webjar注意事项先丢代码地址再丢pom.xml最后丢目录结构WebjarApplicationDemo.html 高级技能，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

            </plugin>
        </plugins>
    </build>


</project>

最后丢目录结构

WebjarApplication

没动过

Demo.html

<!DOCTYPE html>
<html>
<head>
    <script src="/webjars/jquery/3.1.1/jquery.min.js"></script>
    <script src="/webjars/bootstrap/3.3.7-1/js/bootstrap.min.js"></script>
    <title>WebJars Demo</title>
    <link rel="stylesheet" href="/webjars/bootstrap/3.3.7-1/css/bootstrap.min.css" />
</head>
<body>
<div class="container"><br/>
    <div class="alert alert-success">
        <a href="#" class="close" data-dismiss="alert" aria-label="close">×</a>
        Hello, <strong>WebJars!</strong>
    </div>
</div>
</body>
</html>

高级技能

 *
 * 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！！！！！
