Create a project   The project can be successfully started   Then import the code of the front page into the project

Start class

@Slf4j
@SpringBootApplication
public class ReggieApplication {
    public static void main(String[] args) {
        SpringApplication.run(ReggieApplication.class);
        log.info(" The project started successfully ...");
    }
}

Put front-end resources into resources, But there is an inaccessible problem , By default, only static、template Static resources under the static directory , At this time, we need to set the mapping of static resources by configuring classes

The configuration class sets the mapping of static resources

@Slf4j
// This is a configuration class   So add configuration
@Configuration
public class WebMvcConfig extends WebMvcConfigurationSupport {
    /**
     *  Rewriting methods ：registry
     * Method function : Configure the mapping of static resources 
     */

    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        // Resource processor   Map the front page 
        log.info(" Start static resource mapping ...");
        registry.addResourceHandler("/backend/**").addResourceLocations("classpath:/backend/");
        registry.addResourceHandler("/front/**").addResourceLocations("classpath:/front/");
    }
}

Restart the project
