Spring Eureka LoadBalanced RestTemplate when not connected - spring

Question

Here are my dependencies:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
When my Spring Boot application is registered with Eureka, I can define a RestTemplate bean like this:
#Bean
#LoadBalanced
public RestTemplate restTemplate() {
return new RestTemplate();
}
And in my services I can make requests to other services using their registered spring.application.name:
restTemplate.getForEntity("http://application1/test", String.class);
How do I define where http://application1/ is located with Eureka disabled?
eureka.client.enabled=false
Current Implementation test:
#Configuration
public class RibbonConfig {
#Bean
public ServerList<Server> serverServerList() {
return new ConfigurationBasedServerList();
}
}
#Configuration
public class WebConfig {
#Bean
#LoadBalanced
public RestTemplate restTemplate() {
return new RestTemplate();
}
}
#Component
public class TestService implements CommandLineRunner {
#Autowired
private RestTemplate restTemplate;
#Override
public void run(String... args) throws Exception {
ResponseEntity<String> responseEntity = restTemplate.getForEntity("http://application1/test", String.class);
System.out.println(responseEntity);
}
}
#RibbonClient(value = "application1", configuration = RibbonConfig.class)
#SpringBootApplication
public class Demo5Application {
public static void main(String[] args) {
SpringApplication.run(Demo5Application.class, args);
}
}
bootstrap.yml
eureka:
client:
enabled: false
application1:
ribbon:
list-of-servers: http://localhost:8081/

Answer 1

you can define a new RibbonClient configuration for your service this way:
#Configuration
#RibbonClient(name = "application1", configuration = Application1RibbonClientConfiguration.class)
public class Application {
...
}
class Application1RibbonClientConfiguration{
#Bean
public ServerList<Server> ribbonServerList() {
return new ConfigurationBasedServerList();
}
}
you can skip all the configuration above if you don't have eureka on classPath
next in your properties file you can list all the servers location like this:
application1.ribbon.listOfServers=..,..,..
