在春季启动中如何在多个类中使用@Autowired MongoTemplate

Question

Hi I'm relatively new to spring boot and I'm trying to use the mongotemplate using autowired here's my class

@SpringBootApplication
public class Test implements CommandLineRunner {
   public static void main(String[] args) {
       SpringApplication.run(ProducerConsumerApplication.class, args).close();
   }

  @Autowired
  private MongoTemplate mongoTemplate;



  @Override
  public void run(String... strings) throws Exception {
    new Myclass().insert();
  }

This is how my application.yml looks like.

spring:
  kafka:
    bootstrap-servers: 192.168.155.100:9092
    consumer:
      group-id: foo
  data:
    mongodb:
      host: 192.168.155.100
      port: 27017
      database: test

I am trying to use the mongo template in Myclass and I am calling it from the Test class but the mongotemplate is null. How should I be doing this? Any help is appreciated

Answer 1

1. Make MyClass a Bean (annotate the class with @Component or return it from a @Bean method)
2. Autowire the MyClass bean in that Test class
3. In the run method call insert() on that field.
