当我试图在我的 Spring 启动应用程序中启用swagger时，它显示空白页面。我使用的是url https：//localhost：8080/context-path/swagger-ui/我可以获得url https：//localhost：8080/context-path/v2/api/docs的JSON数据。我不明白swagger ui的错误在哪里。有人能帮助我吗？提前感谢。
Swagger配置文件

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
  
    @Bean
      public Docket api() { 
          return new Docket(DocumentationType.SWAGGER_2)  
            .select()                                  
            .apis(RequestHandlerSelectors.any())              
            .paths(PathSelectors.any())                          
            .build();                                           
      }
  
}

我在pom.xml中添加了依赖项

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.5.1 </version>
  <relativePath /> <!-- lookup parent from repository -->
</parent>

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger2</artifactId>
  <version>3.0.0</version>
</dependency>

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-boot-starter</artifactId>
  <version>3.0.0</version>
</dependency>

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger-ui</artifactId>
  <version>2.9.2</version>
</dependency>

我有这样的控制器

@GetMapping public ResponseEntity<ProjectDto> getAllProjects() { ProjectDto projectDto = new ProjectDto(); try { List<ProjectDto> projectDtos = projectService.getAllProjects(); projectDto.setProjectDtos(projectDtos.stream().collect(Collectors.toSet())); return new ResponseEntity<>(projectDto, HttpStatus.OK); } catch (ProjectNotFoundException exception) { LOGGER.info(exception.getMessage(), exception); projectDto.setErrorMsg(exception.getMessage()); return new ResponseEntity<>(projectDto, HttpStatus.BAD_REQUEST); } catch (Exception exception) { LOGGER.info(exception.getMessage(), exception); projectDto.setErrorMsg("Something went wrong with projects"); return new ResponseEntity<>(projectDto, HttpStatus.INTERNAL_SERVER_ERROR); } }
