I'm trying to create microservice with spring boot

I'm trying to create microservice with spring boot. I'll put some part of my code here to see if anyone can help me. I'm using Eureka follow my code:

Eureka-service:

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurekaServiceApplication {

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

}

application.properties:

server.port=8083
spring.application.name=eureka-discovery-service
eureka.client.service-url.defaultZone=http://localhost:8083/eureka
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false

Api-gateway:

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
    
    @SpringBootApplication
    @EnableEurekaClient
    public class ApiGatewayApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(ApiGatewayApplication.class, args);
        }
    
    }

application.properties:

server.port=8080
spring.application.name=api-gateway
eureka.client.service-url.defaultZone=http://localhost:8083/eureka
eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
spring.cloud.gateway.enabled=false
spring.cloud.gateway.routes[0].id = USER
spring.cloud.gateway.routes[0].uri = lb://USER
spring.cloud.gateway.routes[0].predicates = Path=/user/**

User-service-controller:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;

@RestController// This means that this class is a Controller
@RequestMapping(path="/user") // This means URL's start with /demo (after Application path)
public class UserController {
  @Autowired // This means to get the bean called userRepository
         // Which is auto-generated by Spring, we will use it to handle the data
  private UserRepository userRepository;

  @PostMapping(path="/add") // Map ONLY POST Requests
  public @ResponseBody String addNewUser (@RequestParam String name
      , @RequestParam String email) {
    // @ResponseBody means the returned String is the response, not a view name
    // @RequestParam means it is a parameter from the GET or POST request

    User n = new User();
    n.setNome(name);
    n.setEmail(email);
    userRepository.save(n);
    return "Saved";
  }

  @GetMapping(path="/all")
  public @ResponseBody Iterable<User> getAllUsers() {
    // This returns a JSON or XML with the users
    return userRepository.findAll();
  }
}

user-service-application:

package com.example.user;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class UserApplication {

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

}

application.properties:

spring.jpa.hibernate.ddl-auto=none
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:Mysql}:3306/quitanda_app
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQLDialect
#spring.jpa.show-sql: true

server.port=8081
spring.application.name=user
eureka.client.service-url.default-zone=http://localhost:8083/eureka
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

Does anyone have any idea where I'm going wrong?
