两种解决办法

1. 配置WebMvcConfigurer.java
2. 配置文件添加spring.mvc.pathmatch.matching-strategy=ant_path_matcher
3. 项目启动
4. swagger访问，http://localhost:8080/doc.html

具体操作如下： 一、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;

@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);
\}

}

二、配置文件添加

spring.mvc.pathmatch.matching-strategy=ant_path_matcher spring: mvc: pathmatch: matching-strategy: ant_path_matcher
