SpringBoot 禁用 rabbitTemplate 用于兔子健康检查的重试策略 [英] SpringBoot Disable rabbitTemplate retry policy for rabbit health check

问题描述

我的 SpringBoot 配置包含非常强大的 rabbitTemplate 重试策略

My SpringBoot configuration contains very strong retry policy for rabbitTemplate retries

spring:
  rabbitmq:
    template:
      retry:
        enabled: true
        initial-interval: 500
        max-attempts: 10
        multiplier: 5
        max-interval: 60000

这个配置的问题是当健康端点被调用并且rabbitMQ关闭时，连接挂起真的很长时间.

The problem with this configuration is when health endpoint is called and rabbitMQ is down, the connections hangs for really long time.

添加像

spring.rabbitmq.connection-timeout=500 or
spring.rabbitmq.template.receive-timeout=500 or
spring.rabbitmq.template.reply-timeout=500 or 
spring.rabbitmq.requested-heartbeat=1

没有帮助，因为retry.multiplier=5，所以无论如何都会花费很多时间.

does not help, since the retry.multiplier=5, so it will take a lot of time anyway.

如果我们不考虑重试策略是否好，有没有办法禁用rabbitTemplate 对健康检查端点的重试或至少给它一些超时时间?

If we disregard whether the retry policy is good or not, is there a way to disable rabbitTemplate retries for health check endpoint or at least give it some timeout?

推荐答案

您可以覆盖默认的健康指示器 bean 以使用模板而不启用重试...

You can override the default health indicator bean to use a template without retry enabled...

@Configuration
public class MyRabbitHealthIndicatorOverride
        extends CompositeHealthIndicatorConfiguration<RabbitHealthIndicator, RabbitTemplate> {

    @Bean
    public HealthIndicator rabbitHealthIndicator(ConnectionFactory connectionFactory) {
        return createHealthIndicator(new RabbitTemplate(connectionFactory));
    }

}
