Error creating bean with name 'configurationPropertiesBeans' defined in class path resource异常分析

在学习使用alibaba的nacos过程中，编写了一个Spring Cloud的demo实现服务注册，结果一启动项目，就报了如下异常：

通过仔细阅读Nacos手册与分析pom.xml发现是spring-boot的版本与nacos版本不一致的导致。

原pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.4.1-SNAPSHOT</version></parent><groupId>wongoing</groupId><artifactId>nacos</artifactId><version>0.0.1-SNAPSHOT</version><name>NacosServer-1</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>com.alibaba.cloud</groupId><artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId><version>2.2.3.RELEASE</version></dependency></dependencies><build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build><repositories><repository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/milestone</url></repository><repository><id>spring-snapshots</id><name>Spring Snapshots</name><url>https://repo.spring.io/snapshot</url><snapshots><enabled>true</enabled></snapshots></repository></repositories><pluginRepositories><pluginRepository><id>spring-milestones</id><name>Spring Milestones</name><url>https://repo.spring.io/milestone</url></pluginRepository><pluginRepository><id>spring-snapshots</id><name>Spring Snapshots</name><url>https://repo.spring.io/snapshot</url><snapshots><enabled>true</enabled></snapshots></pluginRepository></pluginRepositories></project>

因为使用的事Spring Tool Suite 4直接创建的Spring Boot项目，默认选择了最高版本2.4.1-SNAPSHOT，而当前nacos的最高版本是2.2.3.RELEASE，因此只要把Spring Boot的版本降至与nacos版本一致就可以了。

修改后的pom.xml如下：

<?xml version="1.0" encoding="UTF-8"?>

启动后，就能在Nacos管理界面的服务列表中看到这个服务了。如下图：
