pom.xml中的配置无法被yaml读取

问题描述

项目中指定了多个profiles, 但是application.yaml读取报错，报错信息如下

Standard Commons Logging discovery in action with spring-jcl: please remove commons-logging.jar from classpath in order to avoid potential conflicts
12:41:52.325 [main] ERROR org.springframework.boot.SpringApplication -- Application run failed
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 3, column 13:active: @env@^at org.yaml.snakeyaml.scanner.ScannerImpl.fetchMoreTokens(ScannerImpl.java:445)at org.yaml.snakeyaml.scanner.ScannerImpl.checkToken(ScannerImpl.java:238)at org.yaml.snakeyaml.parser.ParserImpl$ParseBlockMappingValue.produce(ParserImpl.java:669)at org.yaml.snakeyaml.parser.ParserImpl.peekEvent(ParserImpl.java:161)at org.yaml.snakeyaml.comments.CommentEventsCollector$1.peek(CommentEventsCollector.java:57)at org.yaml.snakeyaml.comments.CommentEventsCollector$1.peek(CommentEventsCollector.java:43)

profiles配置如下

<profiles><profile><id>dev</id><properties><env>dev</env></properties><activation><activeByDefault>true</activeByDefault></activation></profile><profile><id>test</id><properties><env>test</env></properties></profile><profile><id>prod</id><properties><env>prod</env></properties></profile>
</profiles>

在这里插入图片描述

application.yaml中的配置

spring:profiles:active: @env@

无论怎么切换profiles，或者刷新maven项目，一直报这个错误。

之前的项目也使用了这个写法，但是没有这个问题

解决方案

在Maven中添加如下配置

<build><resources><resource><directory>src/main/resources</directory><!--开启过滤，用指定的参数替换directory下的文件中的参数--><filtering>true</filtering></resource></resources>
</build>
