java - 通过自动配置作为模块打开附加端口时，应用程序无法启动

Question

我正在尝试创建一个库，可以在第二个端口(8090)上公开 SpringBoot 应用程序。

为此，我有一个自动配置，定义如下:

@Configuration
@ConditionalOnWebApplication(
    type = Type.SERVLET
)
public class HttpConfig {
    public HttpConfig() {
    }

    @Bean
    public ServletWebServerFactory servletContainer() {
        TomcatServletWebServerFactory factory = new TomcatServletWebServerFactory();
        factory.addAdditionalTomcatConnectors(new Connector[]{this.createStanderConnecter()});
        return factory;
    }

    private Connector createStanderConnecter() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setPort(8090);
        return connector;
    }
}

如果我在同一个项目中定义此配置，它就可以正常工作。 但是，如果我将此配置作为模块导入，我的应用程序将无法启动并出现以下错误:

Caused by: org.springframework.context.ApplicationContextException: Unable to start ServletWebServerApplicationContext due to multiple ServletWebServerFactory beans : tomcatServletWebServerFactory,servletContainer

我错过了什么？

我想。如果其他人想要完成我正在努力做的事情。我必须实现 WebServerFactoryCustomizer 而不是配置，如下所示:

@Component
@ConditionalOnWebApplication(
    type = Type.SERVLET
)
public class HttpConfig implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {
    @Autowired
    ApplicationContext context;

    public HttpConfig() {
    }

    public void customize(TomcatServletWebServerFactory factory) {
        factory.addAdditionalTomcatConnectors(new Connector[]{this.createStanderConnecter()});
    }

    private Connector createStanderConnecter() {
        Connector connector = new Connector("org.apache.coyote.http11.Http11NioProtocol");
        connector.setPort(8090);
        return connector;
    }
}
