一、控制台报错信息

二、问题解决,配置WebMvcConfigurer.java

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

/**
 * @author Andon
 * 2021/12/29
 */
@Configuration
public class WebMvcConfigurer extends WebMvcConfigurationSupport {

    /**
     * 发现如果继承了WebMvcConfigurationSupport,则在yml中配置的相关内容会失效。 需要重新指定静态资源
     */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/**").addResourceLocations(
                "classpath:/static/");
        registry.addResourceHandler("swagger-ui.html", "doc.html").addResourceLocations(
                "classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**").addResourceLocations(
                "classpath:/META-INF/resources/webjars/");
        super.addResourceHandlers(registry);
    }

}
