springboot项目application.properties无法打包进target目录,什么原因?

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

回答:

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:

  1. 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。
  2. 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。
  3. 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>

对比一下pom.xml,然后研究下resource是做啥用的
