Javac java jar 命令使用

public class Test{

      public static void main(String [] args){

          System.out.println(“参数为：”+args[0]);   

     }

}

1、执行类

无包

  javac Test.java

  java Test hello

有包

 java com.Test.java

 java com.Test hello

2、执行Jar

无包

jar cfmv test.jar mymanifest Test.class

java -jar test.jar hello

mymainfest内容为：

  1nifest-Version: 1.0
  2Created-By: 1.8.0_60 (Oracle Corporation)
  3Main-Class: Test

  4 

有包

jar cfmv test.jar mymanifest com/Test.class

java -jar test.jar hello

mymainfest内容为：

  1nifest-Version: 1.0
  2Created-By: 1.8.0_60 (Oracle Corporation)
  3Main-Class: com.Test

  4 

3、引入自定义jar

无包

javac -cp "bbtree-commons-core-1.2.46.jar" Test.java

java -classpath "/Users/chenzhilei/.m2/repository/commons-codec/commons-codec/1.8/commons-codec-1.8.jar:bbtree-commons-core-1.2.46.jar:/Users/chenzhilei/.m2/repository/org/bouncycastle/bcprov-jdk15/1.45/bcprov-jdk15-1.45.jar:" Test b1f12a5c4a4c80a59c4bee51e31e5c56 hello

有包

javac -cp "com/bbtree-commons-core-1.2.46.jar" com/Test.java

java -classpath "/Users/chenzhilei/.m2/repository/commons-codec/commons-codec/1.8/commons-codec-1.8.jar:com/bbtree-commons-core-1.2.46.jar:/Users/chenzhilei/.m2/repository/org/bouncycastle/bcprov-jdk15/1.45/bcprov-jdk15-1.45.jar:" com.Test b1f12a5c4a4c80a59c4bee51e31e5c56 hello
