Why I have a connection refused error when starting rabbit by docker-compose?

I run sprinboot app, front (in react), database and rabbitmq in docker-compose. When I run it everything works except rabbitmq. I had an error - "Connection refused".

docker-compose:

version:  '3'
services:
    server:
      build: ./mlogger
      ports:
      - "8000:8080"
      depends_on:
      - database
      restart: always
    web:
      build: ./web
      ports:
      - "4000:3000"
      tty: true
      depends_on:
      - server
    database:
      container_name: 'mysql'
      image: mysql
      environment:
        MYSQL_ROOT_PASSWORD: jitsi1234
        MYSQL_USER: jitsiteam
        MYSQL_DATABASE: testmlogger
      ports:
      - "3306:3306"
      restart: always
    rabbitmq:
      image: rabbitmq:3-management
      container_name: rabbitmq
      command: sh -c "rabbitmq-plugins enable rabbitmq_auth_backend_ldap"
      ports:
      - "5672:5672"
      - "15672:15672"
      restart: always

error:

Spring boot properties:

spring.rabbitmq.address=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

I'm using ldap also, and I want to add users to rabbitmq on start. I can do it by adding commands to docker-compose?

Spring boot ldap config:

@Configuration
@EnableLdapRepositories
public class LdapConfig {

    @Bean
    public LdapContextSource contextSource() {
        LdapContextSource contextSource = new LdapContextSource();
        contextSource.setUrl("ldap://localhost:18889");
        contextSource.setBase("dc=example,dc=com");
        return contextSource;
    }

    @Bean
    public LdapTemplate ldapTemplate() {
        return new LdapTemplate(contextSource());
    }
}

I figured it out, in the docker compose part responsible for the spring application, I had to specify the network mode:

server:
 build: ./mlogger
 ports:
  - "8000:8080"
 depends_on:
  - database
  - rabbitmq
 network_mode: "host"

Inside a container, localhost is the container itself, not the host it is running on. Components are visible to each other with their service names. Insead of connecting to localhost:5672, connect to rabbitmq:5672, and it should work. Do the same for the database as well.
