Eureka service discovery without Spring-boot

Question

I have written a spring boot micro-service and a REST client. The client is a part of another module and make RESTful calls to the micro-service. The micro-service registers

Answer 1

Wish accessing Eureka from legacy spring ( non-boot ) is also made simple like @EnableEureka and @EnableFeignClient

This is the closest I could get it working . This example is available in Eureka-examples in Git Hub

public class EurekaConfiguration {

    private static ApplicationInfoManager applicationInfoManager;
    private static EurekaClient eurekaClient;

    private static synchronized ApplicationInfoManager initializeApplicationInfoManager(
            EurekaInstanceConfig instanceConfig) {
        if (applicationInfoManager == null) {
            InstanceInfo instanceInfo = new EurekaConfigBasedInstanceInfoProvider(instanceConfig).get();
            applicationInfoManager = new ApplicationInfoManager(instanceConfig, instanceInfo);
        }

        return applicationInfoManager;
    }

    private static synchronized EurekaClient initializeEurekaClient(ApplicationInfoManager applicationInfoManager,
            EurekaClientConfig clientConfig) {
        if (eurekaClient == null) {
            eurekaClient = new DiscoveryClient(applicationInfoManager, clientConfig);
        }

        return eurekaClient;
    }
    
    public static EurekaClient getEurekaClient()
    {
        ApplicationInfoManager applicationInfoManager = initializeApplicationInfoManager(new MyDataCenterInstanceConfig());
        EurekaClient client = initializeEurekaClient(applicationInfoManager, new DefaultEurekaClientConfig());
        return client;
    }
}

My client

String vipAddress = "NLPService";

        InstanceInfo nextServerInfo = null;
        try {
            nextServerInfo = EurekaConfiguration.getEurekaClient().getNextServerFromEureka(vipAddress, false);
        } catch (Exception e) {
            System.err.println("Cannot get an instance of example service to talk to from eureka");
            System.exit(-1);
        }

        System.out.println("Found an instance of example service to talk to from eureka: "
                + nextServerInfo.getVIPAddress() + ":" + nextServerInfo.getPort());
        
        String serviceBaseURL = "http://"+ nextServerInfo.getHostName()
        +":"+nextServerInfo.getPort();
       
        
        String nlpServiceURL = serviceBaseURL +"/nlp";
        
        RestTemplate restTemplate = new RestTemplate();
        
        NLPInputToBeTransformed input = new NLPInputToBeTransformed();
        input.setInputText(" Test Input ");
        
        
        NLPResponse nlpResponse = restTemplate.postForObject
                (nlpServiceURL, input, NLPResponse.class, new HashMap<>());
        
        System.out.println( " Service Response  " + nlpResponse.getTags());
