springboot大文件导入（SpringBoot分离资源文件打包）

Spring Boot项目默认的会打包成单一的jar文件，但是有时候我们并不想让配置文件、依赖包都跟可执行文件打包到一起。这时候可以在pom.xml文件中进行配置，从而使资源文件、依赖包和可执行文件分离。pom.xml配置如下：

<build>

<plugins>

maven打包完成后，可以在target目录下看到一个build目录，进入该目录的结构如图：

test.jar文件就是可执行文件，资源文件和配置文件都在resources目录下，依赖的jar包都在lib目录下。

运行方式：java -jar -Dloader.path=.,resources,lib test.jar

注意：如果在windows10系统下运行，要用cmd，不要用PowerShell，否则可能会报Error: Unable to access jarfile .path=.,resources,lib异常。
