        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <profilesActive>dev</profilesActive>
                <activated_yml>dev</activated_yml>
            </properties>
            <build>
                <resources>
                    <resource>
                        <!--<filtering>true</filtering>-->
                        <directory>src/main/resources</directory>

            </build>

        </profile>

打包时能替换文件名，但是不能替换文件里面的标识符：

启动项目时报错：

14:37:32.598 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
java.lang.IllegalStateException: Failed to load property source from location 'classpath:/application.yml'

 

2 在pom.xml中 <filtering>true</filtering>

        <profile>
            <id>dev</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties>
                <profilesActive>dev</profilesActive>
                <activated_yml>dev</activated_yml>
            </properties>
            <build>
                <resources>
                    <resource>
                        <filtering>true</filtering>
                        <directory>src/main/resources</directory>
                        <includes>
                            <include>application.yml</include>
                            <include>application-${activated_yml}.yml</include>
                            <include>logback-dev.xml</include>
                            <include>spring-mvc.xml</include>
                            <include>spring-task.xml</include>
                            <include>mybatis/mapper/*.xml</include>
                            <include>mybatis/mybatis-config.xml</include>
                        </includes>
