maven工程将main函数打成jar包

现将POM.xml文件的代码粘贴如下：

主要用到的是build标签内的代码，其他的都是引入Jar包用的。

把mainClass标签内的代码换成你主函数所在的位置。

然后在项目上右键MAVEN IMSTALL。即可生成该项目的JAR包

-------------------------------------------------------------------------------------------------------

写shell脚本来执行该Main函数

#! /bin/sh
set -x
JAVA_HOME=/home/zqlx/software/jdk1.7.0_07
CLASSPATH=.:/home/zqlx/software/jdk1.7.0_07/lib/dt.jar:/home/zqlx/software/jdk1.7.0_07/lib/tools.jar
cp=${CLASSPATH}
for i in `ls -1 ../lib/*.jar`; do
       cp=${cp}:./$i
done

deal_date=${1:-`date --date '1 days ago' +%Y-%m-%d`}

nohup $JAVA_HOME/bin/java -cp ${cp} -Xms256m -Xmx2048m com.winksi.dotstat.DotStatPvUv ${deal_date} &

-------------------------结束---------------------------------------

nohup.out为终端输出内容

deal_date为向main函数传递的参数

-----------------------------------------------------------------------

执行jar包指定的main函数命令：JAVA -jar ***.jar

如果想执行另一个类的main函数（非pom.xml指定的main）命令：java -classpath dotstat_v2-0.0.1-SNAPSHOT.jar com.winksi.dotstat.TermActiveStat
