Serving a Spring Boot Actuator endpoint on multiple ports

问题

Our main application is being served on port 8443, and we're using management.port to serve our actuator endpoints on port 8444.

Is there a way to get a single endpoint (the health endpoint) to serve on both 8443 and 8444 while leaving the remaining endpoints on port 8444 only?

回答1:

Providing you're using the built in Tomcat container you could:

1. Remove the management port config property
2. Add an additional connector to serve port 8444
3. Add a filter to allow only the health check be accessed on that port

Your code might look something like this.

@ComponentScan
@Configuration
@EnableAutoConfiguration
public class Application extends WebMvcAutoConfiguration.WebMvcAutoConfigurationAdapter implements EmbeddedServletContainerCustomizer {

    @Autowired
    private PortInterceptor portInterceptor;

    public static void main(String[] args) throws Exception {
        SpringApplication application = new SpringApplication(Application.class);
        application.run(args);
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(portInterceptor);
    }

    @Override
    public void customize(ConfigurableEmbeddedServletContainer container) {
        TomcatEmbeddedServletContainerFactory tomcat = (TomcatEmbeddedServletContainerFactory)container;
        Connector connector = new Connector();
        connector.setPort(8444);
        tomcat.addAdditionalTomcatConnectors(connector);
    }
}

@Component
public class PortInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        if(request.getLocalPort() == 8444){
            return isHealthCheckRequest(request);
        }
        return true;
    }
}
