首先建立maven 工程,pom.xml的内容如下:
4.0.0
Excel
Excel
0.0.1-SNAPSHOT
jar
Excel
http://maven.apache.org
UTF-8
/*apache 的poi包主要是处理excel的*/
org.apache.poi
poi
3.11-beta1
com.microsoft.sqlserver
sqljdbc4
4.0
org.apache.poi
poi-ooxml
3.11-beta1
junit
junit
3.8.1
test
/*由于要导出jar包并且发布线上,所以一下配置主要是导出jar的设置*/
maven-assembly-plugin
false
jar-with-dependencies
Excel.ExcelOperate //main入口类
make-assembly
package
assembly
工程目录如下:
主要的处理类是ExcelOperate,里面有读取xlsx格式的excel和写入excel。

工程建立起来后,直接到工程目录(pom.xml所在的目录),cmd输入mvn clean install 就可以在工程目录下target中找到导出的jar 包。
在服务器的 cd /home/work/hotel/java/bin/
jar 包运行脚本:./java -jar /home/tester/Excel-0.0.1-SNAPSHOT.jar Excel.ExcelOperate -Xms1800M -XX:MaxNewSize=256m -server
