Question

我正在尝试创建一个库，该库可以使SpringBoot应用程序暴露在第二个端口（8090）上。

为此，我有一个自动配置，如下所示：

@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;
    }
}

如果我在同一项目中定义此配置，则可以正常工作。但是，如果我将此配置作为模块导入，则我的应用程序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

我想念什么？

我想。如果其他人想完成我想做的事情。除了配置之外，我还必须实现WebServerFactoryCustomizer，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;
    }
}

通过自动配置作为模块打开其他端口时，应用程序无法启动
