Spring Boot, Spring MVC webjars dependencies return 404

Question

I can`t join webjars dependencies to my html page in spring mvc. This is my pom.xml

      <dependency>
        <groupId>org.webjars</groupId>
        <artifactId>webjars-locator</artifactId>
        <version>0.3</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-websocket</artifactId>
    </dependency>

    <dependency>
        <groupId>org.webjars</groupId>
        <artifactId>sockjs-client</artifactId>
        <version>1.0.2</version>
    </dependency>
    <dependency>
        <groupId>org.webjars</groupId>
        <artifactId>stomp-websocket</artifactId>
        <version>2.3.3</version>
    </dependency>
    <dependency>
        <groupId>org.webjars</groupId>
        <artifactId>bootstrap</artifactId>
        <version>3.3.7</version>
    </dependency>
    <dependency>
        <groupId>org.webjars</groupId>
        <artifactId>jquery</artifactId>
        <version>3.1.0</version>
    </dependency>

I use webjars-locator, so i dont need to add webjars to resource handlers manually. But when i load my page it returns 404 for each of webjars dependecies.

<script src="/webjars/jquery/jquery.min.js"></script>
<script src="/webjars/sockjs-client/sockjs.min.js"></script>
<script src="/webjars/stomp-websocket/stomp.min.js"></script>

Add this to your configuration and you should be fine.

@Configuration
public class WebConfiguration implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("/webjars/")
                .resourceChain(false);
        registry.setOrder(1);
    }

}
