2.2 The nacos and spring boot version

Our nacos version:

<dependency>
  <groupId>com.alibaba.cloud</groupId>
  <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
  <version>2.1.3.RELEASE</version>
</dependency>

Our springboot version:

<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>2.4.5</version>
  <relativePath/> <!-- lookup parent from repository -->
</parent>

2.3 The reason of the problem

According to nacos document, the version of nacos and springboot has some rules:

Tip

Version 2.1.x.RELEASE of nacos is compatible with the Spring Boot 2.1.x line. Version 2.0.x.RELEASE is compatible with the Spring Boot 2.0.x line. Version 1.5.x.RELEASE is compatible with the Spring Boot 1.5.x line.

So the key point is that our nacos version is not matching the spring boot version.

2.4 The solution of the problem

So the solution is very easy, we should change the version of springboot to 2.1.x:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.18.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

Not it works!

3. Summary

In this post, I demonstrated how to solve “java.lang.ClassNotFoundException: org.springframework.boot.context.properties.ConfigurationBeanFactoryMetadata” problem when using nacos and springboot, the key point is to match their versions. That’s it, thanks for your reading.
