2、问题分析

分析日志显示无法加载bootstrap.yml配置文件。

Failed to load property source from location 'classpath:/bootstrap.yml'

是由于无法读取pom.xml文件中的 @pom.profile.name@配置：

Caused by: org.yaml.snakeyaml.scanner.ScannerException: while scanning for the next token
found character '@' that cannot start any token. (Do not use @ for indentation)
in 'reader', line 14, column 13:active: @pom.profile.name@

使用 @ 这样的格式是为了让yml读取 maven pom文件中 profile变量，pom.xml中的变量如下：

<!-- 开发环境 -->
<profile>
	<id>dev</id>
	<activation>
		<!--默认激活配置-->
		<activeByDefault>true</activeByDefault>
	</activation>
	<properties>
		<!--当前环境-->
		<pom.profile.name>dev</pom.profile.name>
		<!--Nacos配置中心地址-->
		<pom.nacos.ip>172.18.8.114</pom.nacos.ip>
		<pom.nacos.port>8848</pom.nacos.port>
		<!--Nacos配置中心命名空间,用于支持多环境.这里必须使用ID，不能使用名称,默认为空-->
		<pom.nacos.namespace>ed7d7a02-6463-4db9-a259-0913bfbafebb</pom.nacos.namespace>
		<pom.seata.namespace></pom.seata.namespace>
	</properties>
</profile>

查看pom.xml配置正常，分析可能是由于idea加载maven pom文件缓存问题，尝试重新导入即可。
