Spring boot webjars：无法通过webjar加载javascript库 [英] Spring boot webjars: unable to load javascript library through webjar
问题描述
我有一个春季启动（我使用Thymeleaf进行模板化）项目，我想使用一些jQuery库。
I have a spring boot (I use Thymeleaf for templating) project where I want to use some jQuery libraries.
不幸的是，webjars根本没有加载。我尝试了很多配置，但都失败了。
Unfortunately, the webjars aren't loading at all. I have tried many configuration but all of them failed.
以下是我的HTML页面的代码片段：
Here is the code snippet of my HTML page:
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head lang="en">
<title>JAC</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/>
<script src="http://cdn.jsdelivr.net/webjars/jquery/2.1.4/jquery.js"
th:src="@{/webjars/jquery/2.1.4/jquery.min.js}" type="text/javascript"></script>
<script src="http://cdn.jsdelivr.net/webjars/jquery-file-upload/9.10.1/jquery.fileupload.js" type="text/javascript"
th:src="@{/webjars/jquery-file-upload/9.10.1/jquery.fileupload.min.js}"></script>
<link href="http://cdn.jsdelivr.net/webjars/bootstrap/3.3.5/css/bootstrap.min.css"
th:href="@{/webjars/bootstrap/3.3.5/css/bootstrap.min.css}"
rel="stylesheet" media="screen" />
<link href="http://cdn.jsdelivr.net/webjars/jquery-file-upload/9.10.1/jquery.fileupload.css"
rel="stylesheet" media="screen" />
</head>
我已将它们添加到pom文件中：
I have added them in the pom file:
<dependency>
<groupId>org.webjars.npm</groupId>
<artifactId>jquery</artifactId>
<version>2.1.4</version>
</dependency>
<dependency>
<groupId>org.webjars</groupId>
<artifactId>bootstrap</artifactId>
<version>3.3.5</version>
</dependency>
<dependency>
<groupId>org.webjars</groupId>
<artifactId>jquery-file-upload</artifactId>
<version>9.10.1</version>
</dependency>
但是在调用页面时，我在jquery.min.js和jquery.fileupload.min上获得了404 .js。
But when calling the page I got a 404 on jquery.min.js and jquery.fileupload.min.js.
GET http://localhost:8888/webjars/jquery-file-upload/9.10.1/jquery.fileupload.min.js
2015-09-21 02:02:04.059 home:9
GET http://localhost:8888/webjars/jquery/2.1.4/jquery.min.js 404 (Not Found)
推荐答案
正在引用jquery库。也许您缺少资源处理程序配置。
You are referencing jquery library correctly. Maybe you are missing resource handler configuration.
<mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>
或者如果你使用JavaConfig
Or if you use JavaConfig
@Configuration
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/webjars/**").addResourceLocations("classpath:/META-INF/resources/webjars/");
}
}
如果这不起作用，请检查您是否在classpath上有webjars（打开）你的应用程序JAR在7Zip中并检查webjars资源是否在其中。）
If this will not work, please check if you have webjars on classpath (open your application JAR in 7Zip and check if webjars resources are inside it.)
