spring boot整合apache dubbo时报错:

我的项目环境是<spring-boot.version>2.1.1.RELEASE</spring-boot.version> <dubbo.version>2.7.3</dubbo.version>
是参考官方文档来搭建的,却一直报上面的错误
官方地址是:
https://github.com/apache/dubbo-spring-boot-project/blob/master/README_CN.md

仔细看了下错误,也百度了一下ConfigFileApplicationListener.supportsSourceType(Ljava/lang/Class;)Z这个问题没有找到答案,于是自己检查了一下工程的jar包,发现引入dubbo后spring相关包全是引入的4.3.16版本的,例如: spring-web-4.3.16.RELEASE.jar
spring-context-4.3.16.RELEASE.jar
。。。
我记得spring boot 2.x版本的spring版本都是5.x的,怎么引入dubbo后spring版本不对了呢,看了下依赖,dubbo原来是依赖的spring版本有点低。那为什么官方例子不会错,我这就一直出现这个错误呢?
仔细检查了下上面的pom文件,发现我dependencyManagement中少定义了spring boot版本,官方提供的pom中有定义如下:
<dependencyManagement>
<dependencies>
<!-- Spring Boot -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>${spring-boot.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<!-- Apache Dubbo -->
<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo-dependencies-bom</artifactId>
<version>${dubbo.version}</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
所以报错的原因就是我少了这个。于是我将如下依赖加入到dependencyManagement中就可以了: <!-- Spring Boot -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.1.1.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
