做項目的還是 會發現 很多sdk沒有maven版本的，這個時候只能手動引入jar包
以引入亞馬遜支付的sdk為例
<dependency>
<groupId>org.amzon-pay</groupId>
<artifactId>amazon-pay-3.6.3.jar</artifactId>
<version>1.0</version>
<scope>system</scope>
//jar包路徑相對路徑
<systemPath>${project.basedir}/src/main/resources/jar/amazon-pay-3.6.3.jar</systemPath>
</dependency>
這個引入后可以發現，項目里可以找到sdk里面的方法了，本地運行項目可以發現可以正常啟動，
但是使用打包后在服務器上運行會發現報錯了

排查后發現 ，是由于打包的時候 沒有把我們自己引入的jar 打包進項目
給spring-boot的打包插件設置一下includeSystemScope參數即可
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
//加入這個includeSystemScope
<configuration>
<includeSystemScope>true</includeSystemScope>
</configuration>
</plugin>
</plugins>
</build>
在運行 可以發現 項目可以正常跑起來了
