问题 I am trying to find example of spring cloud stream where it creates parition based producer for RMQ. I want to see how it will create binding for those queues as RMQ not natively support paritions for topic but it will create number of queues equivalent to number of partitions (I read this,I may be wrong). First I want to understand how to create producer using spring cloud stream on RMQ for partition based producer. 回答1: @SpringBootApplication @EnableBinding(Source.class) public class

问题 I am using Spring AMQP for processing the messages in RabbitMQ. Below is the issue: 1. (say) there are 3 messages in ready state inside RabbitMQ 2. First one is picked up by MessageListener and starts processing. (say) It ends up throwing an exception 3. In this case, the container remains up but the remaining 2 messages are not processed until i restart the container. Also the first messages stays in unacknowledged state. Is it the expected behavior? If not, how to make sure that other 2

问题 We're having issues with one of the consumers, and need to debug the code. SimpleRabbitListenerContainerFactory allows to set a ConsumerTagStrategy, which should add tags during logging. @Bean public SimpleRabbitListenerContainerFactory analyzeTransactionListenerContainerFactory(ConnectionFactory connectionFactory, AsyncTaskExecutor asyncTaskExecutor) { connectionFactory.getVirtualHost()); SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory(); factory

问题 I have a spring-boot web application for which I implemented an MDCFilter that adds a UUID to MDC logging context that i can find in the log file. The Filter class looks like this. public class MDCFilter implements Filter { @Override public void init(FilterConfig filterConfig) { } @Override public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException { String requestId = UUID.randomUUID().toString(); MDC.put(REQUEST_ID_KEY, requestId);

问题 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 The problem with this configuration is when health endpoint is called and rabbitMQ is down, the connections hangs for really long time. Adding properties like spring.rabbitmq.connection-timeout=500 or spring.rabbitmq.template.receive-timeout=500 or spring.rabbitmq.template.reply

问题 First of all, I present context of my case: I am using spring-boot and spring-rabbitmq . It is working for me, you should know that I must have implemented custom converter for received messages. (1) From this converter can be thrown exception, for instance in case of inproper message and so on. (2) After successfull converting (no exception) listener is invoked. Then, in the listener it can also be thrown exception. Now, I would like to force two things: (1') Don't requeue message in case of

问题 I am using spring-boot and spring-rabbitmq package. I have some config class and class representing client. This client class has one listener annotated with @RabbitListener . Everything is fine with my config and client - it does work. However, I need to know some details about internals of this client class. Is something special set in a context ? I would like to be able to inject one of three available datasources (three beans). I mean that I would like to be able based on the first symbol

问题 TLDR: Can't seem to pass messages from one RabbitMQ VHost to another RabbitMQ VHost. I'm having an issue with Spring Cloud Dataflow where it appears that despite specifying different RabbitMQ VHosts for source and sink, they don't ever get to the destination Exchange. My dataflow stream looks like this: RabbitMQ Source | CustomProcessor | RabbitMQ Sink RabbitMQ Source reads from a queue on vHostA and RabbitMQ Sink should output to ExchangeBlah on vHostB. However, no messages end up on

问题 I would like to use the capabilities of rabbitmq-consistent-hash-exchange from java client or preferably by using the spring abstraction spring-amqp. Unfortunately I failed to found an example that explain the java usage and reference a jar dependency to include, please advice. 回答1: There is no specific tag for "x-" exchanges. Use CustomExchange for it: <bean id="requestHashExchangeTest" class="org.springframework.amqp.core.CustomExchange"> <constructor-arg name="name" value="test.hash

问题 What's the difference between SimpleMessageListenerContainer and DirectMessageListenerContainer in Spring AMQP? I checked both of their documentation pages, SimpleMessageListenerContainer has almost no explanation on inner workings, and DirectMessageListenerContainer has the following explanation: The SimpleMessageListenerContainer is not so simple. Recent changes to the rabbitmq java client has facilitated a much simpler listener container that invokes the listener directly on the rabbit
