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

<?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"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <artifactId>webjar</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

        <version>1.5.10.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

    </properties>

    <dependencies>
        <dependency>

        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.webjars</groupId>
            <artifactId>bootstrap</artifactId>
            <version>3.3.7-1</version>
        </dependency>

        <dependency>
            <groupId>org.webjars</groupId>
            <artifactId>jquery</artifactId>
            <version>3.1.1</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </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！！！！！

@Controller
public class WebJarController {
    private final WebJarAssetLocator assetLocator = new WebJarAssetLocator();

    @ResponseBody
    @RequestMapping("/webjarslocator/{webjar}/**")
    public ResponseEntity locateWebjarAsset(@PathVariable String webjar, HttpServletRequest request) {
        try {
            String mvcPrefix = "/webjarslocator/" + webjar + "/";
            String mvcPath = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
            String fullPath = assetLocator.getFullPath(webjar, mvcPath.substring(mvcPrefix.length()));
            return new ResponseEntity(new ClassPathResource(fullPath), HttpStatus.OK);
        } catch (Exception e) {
            return new ResponseEntity(HttpStatus.NOT_FOUND);
        }
    }

}
