DOS命令編譯帶有包名的JAVA類

1.當類沒有包時dos下
javac qiuyu.java       //編譯qiuyu類,生產class文件
java  qiuyu              //運行qiuyu類

 

2.當有包名情況下(package exercise;)

javac -d . qiuyu.java(注意-d空一格再打點再空一格)

java exercise.qiuyu

 

 

自定義classpath:

 

設置classpath，把引用到的包放進來，這樣關聯的類就不會缺失了

javac -encoding UTF-8 -classpath E:\kuaipan\study\jar\lucene.jar GraphDatabaseReader.java

 

 

Linux下面：

#!/bin/sh
JAVA_HOME="/usr/local/jdk7"
CLASSPATH="/home/lucene481/WEB-INF/classes"
HEAP="-Xms128m -Xmx128m"
for jar in /home/lucene481/WEB-INF/lib/*.jar
do
CLASSPATH=$CLASSPATH:$jar
done
echo "$CLASSPATH"
nohup "$JAVA_HOME"/bin/java -server -classpath $CLASSPATH ${HEAP} com.test.LoadData
