我用swagger为我的服务添加了以下更改。你可以尝试同样的方法。

@Configuration
@EnableSwagger2
class UserConfig {

@Bean
public Docket apiDocumentationV1() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .paths(PathSelectors.ant("/v1/**"))
            .build()
            .apiInfo(createMetaData())
            .useDefaultResponseMessages(false);
}

private ApiInfo createMetaData() {
    return new ApiInfoBuilder()
            .title("Test Service APIs")
            .description("API to maintain test service.")
            .version("1.0.0")
            .build();
}
}
