错误分析

无法读取pom.xml中的profile.name 参数

解决:

方式一: spring.profiles.active=${profile.name}改为spring.profiles.active=dev (不建议使用)

方式二:

在pom.xml

加入依赖:

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-configuration-processorartifactId>
            <optional>trueoptional>
        dependency>

重新编译项目

检验

这样就可以了
