我收到 https://localhost:8080/swagger-ui.html 的 404

Question

我收到了 http://localhost:8080/v2/api-docs/ 的有效响应，但是当我尝试访问时，我收到了 http://localhost:8080/swagger-ui.html。

这里我附上了pom.xml

        </plugin>
    </plugins>
</build>

在 SwaggerConfig.class 中，

    @Configuration
    @EnableSwagger2
    public class SwaggerConfig {

        @Bean
public Docket api() {
    return new Docket(DocumentationType.SWAGGER_2)
            .select()
            .apis(RequestHandlerSelectors.any())
            .paths(PathSelectors.any())
            .build();
  }}

在这里我附上了我的项目的文件夹结构。 我可以寻求帮助吗？这里我的目标是启用 swagger 文档并访问 swagger-ui。

Answer 1

看起来您正在使用 Swagger v3。Swagger v3 使用/swagger-ui/端点而不是/swagger-ui.html

完整代码：

注意：我使用的是springfox-boot-starter这样我不需要手动配置它（不需要 SwaggerConfig）。

运行并打开网址：http://localhost:8080/swagger-ui/#/

package gt.demo64777725;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@SpringBootApplication
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

@RestController
class CtrlA {

    @GetMapping("/test")
    void abc() {

    }

}
