解决springboot3不兼容rocketmq问题

Love The Way You Lie 2024-03-23 15:42 12阅读 0赞

今天学习springboot整合rocketmq时，使用@Autowired注解自动装配RocketMQTemplate失败

## 报错如下 ##

Description:
    
    Field rocketMQTemplate in com.example.demo17springbootmq.service.rocketmq.MessageServiceRocketmqImpl required a bean of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' that could not be found.
    
    The injection point has the following annotations:
    	- @org.springframework.beans.factory.annotation.Autowired(required=true)
    
    
    Action:
    
    Consider defining a bean of type 'org.apache.rocketmq.spring.core.RocketMQTemplate' in your configuration.

提示RocketMQTemplate无法被找到

(当前日期为2023.04.21)最终发现是版本不兼容问题，rocketmq最新的版本(5.1)目前还不兼容springboot3，因为springboot3修改了一些相关内容

最终在github中rocketmq的官方项目中找到一篇issue解决了这个问题

> Fix: [\#539][539] Support SpringBoot 3.x.
> 
> Springboot-3.0 has abandoned `spring.factories` automatic assembly, it's replace by `/resources/META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports`, add this file for compatibility.

翻译如下

> 修复： \#539 支持SpringBoot 3.x。
> 
> Springboot-3.0已经放弃了spring.plants自动装配，它被/resources/META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.import所取代，添加这个文件是为了兼容。

## 解决方法 ##

在resources目录中创建META-INF文件夹，

在这个文件夹中创建spring文件夹，

在spring文件夹中创建一个名为org.springframework.boot.autoconfigure.AutoConfiguration.import的文件

> org.springframework.boot.autoconfigure.AutoConfiguration.import

即可成功启动
