import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
 
@Configuration
@EnableSwagger2
@EnableWebMvc
public class SwaggerConfig {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.any())
            .paths(PathSelectors.any())
            .build();
    }
}

application.yaml增加配置：

springfox:
  documentation:

FAQ

1. Failed to start bean 'documentationPluginsBootstrapper'

解决办法：在启动类加一个注解：@EnableWebMvc

2. Could not resolve view with name 'forward:/swagger-ui/index.html' in servlet with name 'dispatcherServlet'
