异常的原因：
在于SpringBoot2.4.0升级了maven-resources-plugin到3.2.0版本，且工程中的application.properties不是UTF-8编码，在编译时出现异常。但实际上maven-resources-plugin 3.1.0版本没有这个问题。有人已经在maven官网提出了这个issue。
一开始，笔者以为是SpringBoot打包插件的异常，所以也给SpringBoot提出了这个问题。请看SpringBoot issue

这个异常有两个解决方案：
方案1
修改application.properties文件的编码方式,选用UTF-8编码方式，idea中设置如下

方案2(不推荐)
降级maven-resources-plugin的版本到3.1.0

<plugin>
	<groupId>org.apache.maven.pluginsgroupId>
	<artifactId>maven-resources-pluginartifactId>
	<version>3.1.0version>
