很神奇，同一个系统环境，maven也是同一个，一个项目的application.properties无法打包进target目录，另一个可以。都尝试过先clean再编译，结果一样。不知道为什么原因。附上pom.xml文件。1.不打包的

2.可以打包的

好好研究下pom.xml这个文件，还有里面的标签是干什么的？尤其是resource是做啥用的？

在 Spring Boot 项目中，application.properties 文件是默认会被打包进入 target 目录中的，如果你发现这个文件没有被打包，可能是以下几种原因：

没有放在正确的位置请确认你的 application.properties 文件确实放在了 src/main/resources 目录下。如果不在这个目录下，Maven 打包时就无法将其打包进 target 目录中。
配置文件名称不正确如果你使用的是 YAML 格式的配置文件，文件名应该为 application.yml。如果你想使用 properties 格式的配置文件，则应该将其命名为 application.properties。
Maven 配置不正确请确保在 pom.xml 文件中正确配置了资源过滤，如下所示：

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
        </resource>
    </resources>
</build>
