本文详细介绍了如何在SpringBoot应用中配置RabbitMQ的重试机制，包括数据库连接池、Redis缓存、RabbitMQ消息队列等核心组件的配置参数。通过示例代码展示了如何设置重试策略、回退策略以及任务执行器，实现消息的可靠投递。

SpringBoot RabbitMQ Retry(重发)配置

1.RabbitMQ application.properties

#database config
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&amp;characterEncoding=utf-8&amp;allowMultiQueries=true

spring.datasource.initialSize=5
spring.datasource.minIdle=5
spring.datasource.maxActive=20
spring.datasource.maxWait=60000
spring.datasource.timeBetweenEvictionRunsMillis=60000
spring.datasource.minEvictableIdleTimeMillis=300000

#redis config
spring.redis.database=2
spring.redis.hostname=192.168.1.197
spring.redis.password=walrus
spring.redis.port=6379

#redis pool config
spring.redis.pool.maxActive=200
spring.redis.pool.maxWait=12000
spring.redis.pool.maxIdle=50
spring.redis.pool.minIdle=10

#rabbit mq config
