Java Rabbitmq:在无限循环中重新处理失败的消息

这是我拥有的rabbitmq配置：

<rabbit:admin connection-factory="rmqConnectionFactory"/>

<bean id="**retryAdvice**" class="org.springframework.amqp.rabbit.config.StatefulRetryOperationsInterceptorFactoryBean">
    <property name="retryOperations" ref="retryTemplate"/>
</bean>

<bean id="**retryTemplate**" class="org.springframework.retry.support.RetryTemplate">
    <property name="retryPolicy" ref="simpleRetryPolicy"/>
    <property name="backOffPolicy">
        <bean class="org.springframework.retry.backoff.FixedBackOffPolicy">
            <property name="backOffPeriod" value="5000"/>
        </bean>
    </property>
    <property name="retryContextCache" ref="retryContext"/>
</bean>

<bean id="**retryContext**" class="org.springframework.retry.policy.MapRetryContextCache"/>

<bean id="**simpleRetryPolicy**" class="org.springframework.retry.policy.SimpleRetryPolicy">
    <property name="maxAttempts" value="3"/>
</bean>

<!-- Spring AMQP Template -->
<bean id="**rabbitTemplate**" class="org.springframework.amqp.rabbit.core.RabbitTemplate">
    <property name="connectionFactory" ref="rmqConnectionFactory"/>
    <property name="messageConverter" ref="stdJsonMessageConverter"/>
</bean>

<bean id="**stdJsonMessageConverter**" class="org.springframework.amqp.support.converter.JsonMessageConverter">
    <property name="createMessageIds" value="true"/>
</bean>

<rabbit:admin connection-factory="rmqConnectionFactory"/>

<bean id="**retryAdvice**" class="org.springframework.amqp.rabbit.config.StatefulRetryOperationsInterceptorFactoryBean">
    <property name="retryOperations" ref="retryTemplate"/>
</bean>

<bean id="**retryTemplate**" class="org.springframework.retry.support.RetryTemplate">
    <property name="retryPolicy" ref="simpleRetryPolicy"/>
    <property name="backOffPolicy">
        <bean class="org.springframework.retry.backoff.FixedBackOffPolicy">
            <property name="backOffPeriod" value="5000"/>
        </bean>
    </property>
    <property name="retryContextCache" ref="retryContext"/>
</bean>

<bean id="**retryContext**" class="org.springframework.retry.policy.MapRetryContextCache"/>

<bean id="**simpleRetryPolicy**" class="org.springframework.retry.policy.SimpleRetryPolicy">
    <property name="maxAttempts" value="3"/>
</bean>

<!-- Spring AMQP Template -->
<bean id="**rabbitTemplate**" class="org.springframework.amqp.rabbit.core.RabbitTemplate">
    <property name="connectionFactory" ref="rmqConnectionFactory"/>
    <property name="messageConverter" ref="stdJsonMessageConverter"/>
</bean>

<bean id="**stdJsonMessageConverter**" class="org.springframework.amqp.support.converter.JsonMessageConverter">
    <property name="createMessageIds" value="true"/>
</bean>

我的队列配置如下：

<rabbit:admin connection-factory="rmqConnectionFactory"/>

<bean id="**retryAdvice**" class="org.springframework.amqp.rabbit.config.StatefulRetryOperationsInterceptorFactoryBean">
    <property name="retryOperations" ref="retryTemplate"/>
</bean>

<bean id="**retryTemplate**" class="org.springframework.retry.support.RetryTemplate">
    <property name="retryPolicy" ref="simpleRetryPolicy"/>
    <property name="backOffPolicy">
        <bean class="org.springframework.retry.backoff.FixedBackOffPolicy">
            <property name="backOffPeriod" value="5000"/>
        </bean>
    </property>
    <property name="retryContextCache" ref="retryContext"/>
</bean>

<bean id="**retryContext**" class="org.springframework.retry.policy.MapRetryContextCache"/>

<bean id="**simpleRetryPolicy**" class="org.springframework.retry.policy.SimpleRetryPolicy">
    <property name="maxAttempts" value="3"/>
</bean>

<!-- Spring AMQP Template -->
<bean id="**rabbitTemplate**" class="org.springframework.amqp.rabbit.core.RabbitTemplate">
    <property name="connectionFactory" ref="rmqConnectionFactory"/>
    <property name="messageConverter" ref="stdJsonMessageConverter"/>
</bean>

<bean id="**stdJsonMessageConverter**" class="org.springframework.amqp.support.converter.JsonMessageConverter">
    <property name="createMessageIds" value="true"/>
</bean>

<rabbit:queue name="${queue}" durable="true">
    <rabbit:queue-arguments>
        <entry key="x-ha-policy" value="all"/>
    </rabbit:queue-arguments>
</rabbit:queue>

<rabbit:direct-exchange name="${exchange}">
    <rabbit:bindings>
        <rabbit:binding queue="${queue}" key="${routingKey}"/>
    </rabbit:bindings>
</rabbit:direct-exchange>

当我第一次在exchange上发布消息时，侦听器失败，出现空ID异常。我清除了包含坏消息的队列。尽管如此，每次我启动服务时，都会重试失败的消息处理，并持续失败，直到出现RetryCacheCapacityExceed异常

<rabbit:admin connection-factory="rmqConnectionFactory"/>

<bean id="**retryAdvice**" class="org.springframework.amqp.rabbit.config.StatefulRetryOperationsInterceptorFactoryBean">
    <property name="retryOperations" ref="retryTemplate"/>
</bean>

<bean id="**retryTemplate**" class="org.springframework.retry.support.RetryTemplate">
    <property name="retryPolicy" ref="simpleRetryPolicy"/>
    <property name="backOffPolicy">
        <bean class="org.springframework.retry.backoff.FixedBackOffPolicy">
            <property name="backOffPeriod" value="5000"/>
        </bean>
    </property>
    <property name="retryContextCache" ref="retryContext"/>
</bean>

<bean id="**retryContext**" class="org.springframework.retry.policy.MapRetryContextCache"/>

<bean id="**simpleRetryPolicy**" class="org.springframework.retry.policy.SimpleRetryPolicy">
    <property name="maxAttempts" value="3"/>
</bean>

<!-- Spring AMQP Template -->
<bean id="**rabbitTemplate**" class="org.springframework.amqp.rabbit.core.RabbitTemplate">
    <property name="connectionFactory" ref="rmqConnectionFactory"/>
    <property name="messageConverter" ref="stdJsonMessageConverter"/>
</bean>

<bean id="**stdJsonMessageConverter**" class="org.springframework.amqp.support.converter.JsonMessageConverter">
    <property name="createMessageIds" value="true"/>
</bean>

我的失败消息是否已缓存在某个位置？有没有办法澄清这一点？

此外，为什么即使我的retrytemplate建议以5秒的间隔重新尝试3次，重试仍会继续？

当您使用有状态重试时，每个消息id的重试状态都保存在缓存中（因此我们知道何时停止）

<rabbit:admin connection-factory="rmqConnectionFactory"/>

<bean id="**retryAdvice**" class="org.springframework.amqp.rabbit.config.StatefulRetryOperationsInterceptorFactoryBean">
    <property name="retryOperations" ref="retryTemplate"/>
</bean>

<bean id="**retryTemplate**" class="org.springframework.retry.support.RetryTemplate">
    <property name="retryPolicy" ref="simpleRetryPolicy"/>
    <property name="backOffPolicy">
        <bean class="org.springframework.retry.backoff.FixedBackOffPolicy">
            <property name="backOffPeriod" value="5000"/>
        </bean>
    </property>
    <property name="retryContextCache" ref="retryContext"/>
</bean>

<bean id="**retryContext**" class="org.springframework.retry.policy.MapRetryContextCache"/>

<bean id="**simpleRetryPolicy**" class="org.springframework.retry.policy.SimpleRetryPolicy">
    <property name="maxAttempts" value="3"/>
</bean>

<!-- Spring AMQP Template -->
<bean id="**rabbitTemplate**" class="org.springframework.amqp.rabbit.core.RabbitTemplate">
    <property name="connectionFactory" ref="rmqConnectionFactory"/>
    <property name="messageConverter" ref="stdJsonMessageConverter"/>
</bean>

<bean id="**stdJsonMessageConverter**" class="org.springframework.amqp.support.converter.JsonMessageConverter">
    <property name="createMessageIds" value="true"/>
</bean>

如果没有ID，消息将失败（并继续传递），除非您将

MissingMessageIdAdvice

添加到通知链（在重试侦听器之前），这将允许对没有ID的消息进行1次重试
