Linux服务器中shell调用java类

来源：互联网发布：灯火阑珊网络电视编辑：程序博客网时间：2024/05/18 01:36

LINUX服务器上，startClass.sh脚本，内容配置如下，需要修改几项，则可以调用JAR包文件。（最简版）

#!/bin/sh
###JDK必须重新填写
if [ "$JAVA_HOME" = "" ]; then
JAVA_HOME="/usr/local/java/jdk1.6.0_21"
fi

JAVACMD="$JAVA_HOME/bin/java"
JAVADBG="$JAVA_HOME/bin/java -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=11001,server=y,suspend=n"
CLASS_HOME=""
###主类必须重新填写
SERVICE_CLASS="com.gas.test.requestgis.GisRequest"

LC_ALL=zh_CN.GB18030
export LC_ALL

oldCP=$CLASSPATH
###JAR包位置必须重新填写
unset CLASSPATH
for i in /usr/local/gas/gASHome/projects/wlva/modules/requestgis/* ; do
if [ "$CLASSPATH" != "" ]; then
CLASSPATH=${CLASSPATH}:$i
else
CLASSPATH=$i
fi
done

if [ "$CLASS_HOME" != "" ]; then
for i in ${CLASS_HOME}/* ; do
    if [ "$CLASSPATH" != "" ]; then
      CLASSPATH=${CLASSPATH}:$i
    else
      CLASSPATH=$i
    fi
done
fi

if [ "$oldCP" != "" ]; then
CLASSPATH=${CLASSPATH}:${oldCP}
fi

${JAVACMD} -cp $CLASSPATH ${SERVICE_CLASS}

exit 0
