Spring boot properties:

  1. spring.rabbitmq.address=localhost
  2. spring.rabbitmq.port=5672
  3. spring.rabbitmq.username=guest
  4. 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:

  1. @Configuration
  2. @EnableLdapRepositories
  3. public class LdapConfig {
  5.     @Bean
  6.     public LdapContextSource contextSource() {
  7.         LdapContextSource contextSource = new LdapContextSource();
  8.         contextSource.setUrl("ldap://localhost:18889");
  9.         contextSource.setBase("dc=example,dc=com");
  10.         return contextSource;
  11.     }
  13.     @Bean
  14.     public LdapTemplate ldapTemplate() {
  15.         return new LdapTemplate(contextSource());
  16.     }
  17. }

我弄清楚了，在负责Spring应用程序的Docker Compose部分，我必须指定网络模式：

  1. server:
  2.  build: ./mlogger
  3.  ports:
  4.   - "8000:8080"
  5.  depends_on:
  6.   - database
  7.   - rabbitmq
  8.  network_mode: "host"
英文:

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

  1. server:
  2.  build: ./mlogger
  3.  ports:
  4.   - "8000:8080"
  5.  depends_on:
  6.   - database
  7.   - rabbitmq
  8.  network_mode: "host"

在容器内部，localhost 表示的是容器本身，而不是它运行在的主机。各组件可以通过其服务名称相互访问。所以，不要连接到 localhost:5672，而是连接到 rabbitmq:5672，这样应该就可以正常工作。对于数据库也是同样的方式。

英文:

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.
