我在Springboot项目中从springfox迁移到OpenApi 3，因为我们需要升级到最新的Springboot版本2.7.0
我需要为不同的环境配置自定义contextPath，如下所示

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.0</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>
<dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-ui</artifactId>
            <version>1.6.8</version>
        </dependency>
        <dependency>

// SwaggerConfig类别

@Configuration
@Profile({ "local", "dev", "qat", "uat" })
public class SwaggerConfig {
@Bean
    public OpenAPI openAPI() {
        return new OpenAPI().info(info());
    }
    private Info info() {
         return new Info()
        .title(title)
        .version(version)
        .license(new License().name(licenseName).url(licenseUrl));
        }
}

//application.properties

spring.application.name=myApp
server.servlet.context-path=/api/${spring.application.name}

有了上面的配置，我就可以使用下面的url运行swagger，并从控制器API获取所有需要的响应http：//localhost：8082/api/myApp/swagger-ui/index. html #/
为了在其他环境中配置Swaggerurl，我尝试创建一个如下的侦听器配置类，但没有成功

@Component
public class SwaggerListener implements ApplicationListener<ApplicationPreparedEvent> {
    final ApplicationPreparedEvent event = null;
    @Override
    public void onApplicationEvent(final ApplicationPreparedEvent event) {
        ConfigurableEnvironment environment = event.getApplicationContext().getEnvironment();
        Properties properties = new Properties();
        properties.put("springdoc.swagger-ui.path", swaggerPath(event));
        environment.getPropertySources().addFirst(new PropertiesPropertySource("programmatically", properties));
    }
    private String swaggerPath(final ApplicationPreparedEvent event) {
        String basePath = null;
        String swagger = "swagger-ui/index.html";
        ConfigurableEnvironment environment = event.getApplicationContext().getEnvironment();
        String[] profilesList = environment.getActiveProfiles();
        List<String> profiles = Arrays.asList(profilesList);
        String contextPath = environment.getProperty("server.servlet.context-path");
        if (profiles != null && (profiles.contains("local"))) {
            basePath = swagger;
        } else if (profiles != null && profiles.contains("dev")) {
            basePath = "/dev/api/myApp/" + swagger;
        } else if (profiles != null && (profiles.contains("qat") || profiles.contains("uat"))) {
            basePath = "/api/myApp/";
        }
        return basePath;
    }
}

正在将上述侦听器添加到主类

@SpringBootApplication(scanBasePackages = { "com.myApp.controller" })
@OpenAPIDefinition
public class myApi {
    public static void main(String[] args) {
        SpringApplication springApplication = new SpringApplication(myApi.class);
        springApplication.addListeners(new SwaggerListener());      
        springApplication.run(args);
    }
}

上面的侦听器配置不起作用，有人能帮我吗？让我知道我在这里错过了什么？
