如何在服务器上运行main方法

1. 新建maven项目,编写测试类，和main方法，在pom.xml文件中添加如下内容：

 

<packaging>jar</packaging>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <jdk.version>1.8</jdk.version>
  </properties>

<!-- 添加相应的依赖包 -->

<build>
		<plugins>
		<plugin>  
			    <groupId>org.apache.maven.plugins</groupId>  
			    <artifactId>maven-jar-plugin</artifactId>  
			    <version>2.4</version>  
			    <configuration>
			    	<source>${jdk.version}</source>
					<target>${jdk.version}</target>
					<encoding>${project.build.sourceEncoding}</encoding>
        			
			   		<classesDirectory>target/classes</classesDirectory>
			        <archive>  
			            <manifest>
			                <addClasspath>true</addClasspath>  
			                <classpathPrefix>./</classpathPrefix>  
			                <mainClass>com.crt.member.sersordata.MemberService</mainClass>  
			            </manifest>  
			        </archive> 
			   		<outputDirectory>${project.build.directory}/lib</outputDirectory>
			    </configuration>  
			</plugin>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-dependency-plugin</artifactId>
				<executions>
					<execution>
						<id>copy</id>
						<phase>package</phase>
						<goals>
							<goal>copy-dependencies</goal>
						</goals>
						<configuration>
							<outputDirectory>${project.build.directory}/lib</outputDirectory>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>

 2. 通过mvn clean package 对该项目进行打包，依赖的包会打在target/lib目录下

 

 3. 编写start.sh执行脚本

 

#!/bin/bash
source /etc/profile

if [ "`ps -ef |grep crt-apigateway.jar|grep -v grep |awk '{print $2}'`" ];then
 for pid in `ps -ef |grep crt-apigateway.jar|grep -v grep |awk '{print $2}'`;do
   kill -9 $pid
 done
fi
#export JAVA_HOME=/app/jdk
export PATH=$JAVA_HOME/bin:$PATH

APP_HOME=/tmp/sersordata/target/lib
for i in "$APP_HOME"/*.jar
do
 CLASSPATH="$CLASSPATH":"$i"
done

export CLASSPATH=.:$CLASSPATH

 echo ${CLASSPATH}
 echo $JAVA_HOME


java -Xms2048M -Xmx2048M -Xmn512M -Xss256K -XX:+DisableExplicitGC -XX:SurvivorRatio=1 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSParallelRemarkEnabled -XX:+UseCMSCompactAtFullCollection -XX:CMSFullGCsBeforeCompaction=0 -XX:+CMSClassUnloadingEnabled -XX:LargePageSizeInBytes=128M -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=70 -XX:SoftRefLRUPolicyMSPerMB=0 -Dfile.encoding=UTF-8 -Xms32m -Xmx200m com.crt.member.sersordata.MemberService -classpath ${CLASSPATH}

 4. 把项目包和start.sh放到服务器目录下，执行start.sh文件，main方法将会得到执行。
