Eureka; cannot pass request through eureka server - netflix-eureka

Question

Help to solve the problem, I cannot make a request to the second application through the eureka service.
Here is my code:
#SpringBootApplication
#EnableEurekaServer
public class EurekaServerApplication {
public static void main(String[] args) {
SpringApplication.run(EurekaServerApplication.class, args);
}
}
server.port=8761
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
#SpringBootApplication
#EnableEurekaClient
public class ClientFirstApplication {
public static void main(String[] args) {
SpringApplication.run(ClientFirstApplication.class, args);
}
}
#RestController
public class ClientFirstController {
static final String SERVER_FIRST_URL = "http://SERVER-FIRST/";
#Bean
#LoadBalanced
public RestTemplate getRestTemplate(){
return new RestTemplate();
}
#Autowired
public RestTemplate restTemplate;
#GetMapping("/home")
public String home(){
return "<h1> This is Home page for Client First</h1>";
}
#GetMapping("/connectserver")
public String serverFirstConnect(){
return restTemplate.getForObject(SERVER_FIRST_URL+"homeserver", String.class);
}
}
server.port=0
spring.application.name=CLIENT-FIRST
eureka.instance.instance-id=${spring.application.name}:${random.uuid}
eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
spring.main.allow-circular-references=true
#SpringBootApplication
#EnableEurekaClient
public class ServerFirstApplication {
public static void main(String[] args) {
SpringApplication.run(ServerFirstApplication.class, args);
}
}
#RestController
public class ServerFirstController {
#GetMapping("/homeserver")
public String home(){
return "<h1> This is Home page for Server First</h1>";
}
#GetMapping("/user")
public String user(){
return "<h1> This is User page for Server First</h1>";
}
}
server.port=0
spring.application.name=SERVER-FIRST
eureka.instance.instance-id=${spring.application.name}:${random.uuid}
eureka.client.service-url.defaultZone=http://localhost:8761/eureka/
when I go to the link http://localhost:62555/connectserver
, there is always an error
but
when I follow the link with this link http://localhost:62555/user
, everything works
