Невозможно сделать сервис для обслуживания связи с SpringBoot и RestTemplate

Question

У меня есть 2 приложения SpringBoot в качестве службы покоя, когда я пытаюсь установить связь между этими двумя службами, я не могу получить ответ из одной службы в другую. Мой код выглядит следующим образом.

Может кто-нибудь сказать мне, что не так в моем коде, из-за чего каждый раз, когда мой код входит в резервный метод.

1.EmployeeApplication

package io.employee.breaker;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;


@RestController
@SpringBootApplication
public class EmployeeApplication {
    private static final Logger log = LoggerFactory.getLogger(EmployeeApplication.class);
    @RequestMapping("/getEmployee")
    public Employee getEmployee() {
        log.info("Inside EmployeeApplication");
        Employee emp = new Employee(1,"Ankit");
        log.info("Return value");
        return emp;
    }

    public static void main(String[] args) {
        SpringApplication.run(EmployeeApplication.class, args);
    }
}

2.ReadEmployeeApplication

 package io.employee.breaker;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@EnableCircuitBreaker
@RestController
@SpringBootApplication
@RequestMapping("/employee")
public class ReadEmployeeApplication {
    private static final Logger log = LoggerFactory.getLogger(ReadEmployeeApplication.class);
    public static void main(String[] args) {
        SpringApplication.run(ReadEmployeeApplication.class, args);
    }

    @Autowired
    private EmployeeService employeeService;

    @RequestMapping("/to-read")
    public Employee toRead() {
        log.info("Inside to read");
        return employeeService.readingList();
    }
}
