在idea环境中引入本地下载的jar包

1. 在项目工程中新建lib

 

 

 2. 通过maven命令完成jar安装

 mvn install:install-file
 -Dfile=E:\idea\longyan\lib\poi-ooxml-4.1.2.jar
 -DgroupId=poi-ooxml
 -DartifactId=poi-ooxml
 -Dversion=4.1.2
 -Dpackaging=jar

 

 

 3. 配置pom

<!--poi-->
<dependency>
   <groupId>poi</groupId>
   <artifactId>poi</artifactId>
   <version>4.1.2</version>
</dependency>
<dependency>
   <groupId>poi-ooxml</groupId>
   <artifactId>poi-ooxml</artifactId>
   <version>4.1.2</version>
</dependency>
4. 打包上线需要增加配置

<plugins>
   <plugin>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-maven-plugin</artifactId>
      <configuration>
         <includeSystemScope>true</includeSystemScope>
      </configuration>
   </plugin>
</plugins>
