rabbitmq的消費者消費不了消息的情況彙總

1. 問題描述

         通過rabbitmq隊列，消費方出現不能消費消息的情況，經過細查rabbitmq的配置沒有問題,然而消費方不能執行邏輯。

 

  交換機配置exchange:

 

  交換機綁定的隊列:
 

       同樣也發現properties文件中的配置是正確的:

spring.rabbitmq.port = 5672
spring.rabbitmq.username = admin
spring.rabbitmq.password = Aegon_2018
spring.rabbitmq.virtual-host = /fec-uat
spring.rabbitmq.host = rabbitmq-fec.dev

       

 2.解決方案

        最後發現沒有添加@RestController註解。 繼承了AbstractWorkflowEventConsumerInterface的類上添加@RestController註解，即可解決問題！

      經過查看源碼發現，最終執行的approve方法，是一個restFul接口，因此需要在類上添加一個@RestController將接口暴露出來。

@RestController
public class WorkflowEventConsumer extends AbstractWorkflowEventConsumerInterface {}

 

     其中  

@PostMapping({"/api/implement/workflow/approve"}) public abstract ApprovalResultCO approve(@RequestBody ApprovalNotificationCO approvalNoticeCO);

    是一個restFul接口。
