SpringBoot不加载使用OpenAPI 3.0生成的控制器

Question

我正在使用openapi-generator-maven-plugin生成代码。代码正在成功生成。但是spring boot并没有在上下文中加载生成的代码。我不知道为什么，因为我做了以下事情。

下面是我的插件配置：

<plugin>
    <groupId>org.openapitools</groupId>
    <artifactId>openapi-generator-maven-plugin</artifactId>
    <version>4.3.1</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <inputSpec>${project.basedir}/src/main/resources/spec/SchoolAPIs.v1.yaml</inputSpec>
                <output>${project.build.directory}/server</output>
                <language>spring</language>
                <apiPackage>com.school.rest.controllers</apiPackage>
                <modelPackage>com.school.rest.generated.dtos</modelPackage>
                <supportingFilesToGenerate>ApiUtil.java</supportingFilesToGenerate>
                <library>spring-boot</library>
                <configOptions>
                    <java8>false</java8>
                    <dateLibrary>java8</dateLibrary>
                    <delegatePattern>true</delegatePattern>
                    <useBeanValidation>true</useBeanValidation>
                </configOptions>
            </configuration>
        </execution>
    </executions>
</plugin>

下面是我指定配置的主类：

@EnableSwagger2
@EnableAsync
@SpringBootApplication(exclude = SecurityAutoConfiguration.class, scanBasePackages = { "com.school.rest"})
@EnableJpaRepositories(basePackages = "com.school.rest.repository")
@Slf4j
public class SchoolAPIApplication implements CommandLineRunner {

    public static void main(String[] args) {
        ApplicationContext context = new SpringApplicationBuilder(SchoolAPIApplication.class)
                .registerShutdownHook(true).run(args);
        PlansApiController plansApiController = context.getBean(PlansApiController.class);
        log.info(">>>>>>>>>>>>>>>>>>>>>>>>>>>> {}", plansApiController);
    }

}

我不知道这里出了什么问题，我已经为这个问题挣扎了近2天。找不到丢失的是什么。

如果您有任何可用的解决方案，请告诉我。

更新:此调用产生以下error>

log.info(">>>>>>>>>>>>>>>>>>>>>>>>>>>> {}", plansApiController);

错误：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type...

问候

从我所看到的，你生成的包在启动时没有被扫描。我已经尝试在这里重现你的问题和解决方案，https://github.com/tinashehondo/notifications-api

                        <configOptions>
                            <java8>false</java8>
                            <dateLibrary>java8</dateLibrary>
                            <delegatePattern>true</delegatePattern>
                            <useBeanValidation>true</useBeanValidation>
                        </configOptions>
                    </configuration>
                </execution>
            </executions>
        </plugin>

和

@SpringBootApplication(exclude = SecurityAutoConfiguration.class,
     scanBasePackages = { "uk.co.tinashehondo.notifications.rest"})
 public class App {
   public static void main(String[] args) {
    ApplicationContext context = new        SpringApplicationBuilder(App.class)
            .registerShutdownHook(true).run(args);
    NotificationApi notificationApiController =    context.getBean(NotificationApi.class);
    System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>> {}"+notificationApiController); //forgive sys.out here
}

}

输出

>>>>>>>>>>>>>>>>>>>>>>>>>>>>     {}uk.co.tinashehondo.notifications.rest.api.NotificationApiController@7b948f3e

Answer 2

好吧，对我来说答案是这样的，

我之所以面临这个问题，是因为较低的spring-boot版本不支持从生成的接口读取数据。由于这个原因，代码生成器正在生成带有带有所有文档注释的接口的代码，但是它们不会被spring读取并添加到上下文中。

将我的spring版本从2.0.0升级到2.1.4，事情就解决了。张贴在这里供其他人参考。
