Spring - RabbitMQ循环依赖问题解决

代码整合 actuator 后，启动报错，出现rabbitMQ循环依赖的问题

异常信息：

***************************
APPLICATION FAILED TO START
***************************

Description:

The dependencies of some of the beans in the application context form a cycle:

   servletEndpointRegistrar defined in class path resource [org/springframework/boot/actuate/autoconfigure/endpoint/web/ServletEndpointManagementContextConfiguration$WebMvcServletEndpointManagementContextConfiguration.class]
      ↓
   healthEndpoint defined in class path resource [org/springframework/boot/actuate/autoconfigure/health/HealthEndpointConfiguration.class]
      ↓
   healthIndicatorRegistry defined in class path resource [org/springframework/boot/actuate/autoconfigure/health/HealthIndicatorAutoConfiguration.class]
      ↓
   org.springframework.boot.actuate.autoconfigure.amqp.RabbitHealthIndicatorAutoConfiguration
┌─────┐
|  rabbitTemplate defined in class path resource [org/springframework/boot/autoconfigure/amqp/RabbitAutoConfiguration$RabbitTemplateConfiguration.class]
↑     ↓
|  myRabbitConfig (field org.springframework.amqp.rabbit.core.RabbitTemplate com.xxxx.gulimall.order.config.MyRabbitConfig.rabbitTemplate)
└─────┘

解决方法：

1. 注释掉 @Autowired和@PostConstruct注解
2. 自己给容器中放一个RabbitTemplate,参考RabbitAutoConfiguration$RabbitTemplateConfiguration.class
3. 手动初始化模板方法

@Primary
@Bean
public RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
    RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
    this.rabbitTemplate = rabbitTemplate;
    rabbitTemplate.setMessageConverter(messageConverter());
    initRabbitTemplate();
    return rabbitTemplate;
}
