java程序运行库 java运行程序的命令

1.在 eclipse或myeclipse中运行程序。

 

2.在命令控制台cmd中输入命令运行程序。

先编译类，在运行

javac example.class---->java example.

 

3.将JAVA程序以.bat形式运行。

界面.bat

在脚本中，你只需要设置CLASSPATH和依赖的jar包的位置

（set CLASSPATH=%CLASSPATH%;%.\lib\ibatis-sqlmap-2.jar）；

程序的主入口（set _MAINCLASS=com.jrj.genius.api.client.action.HKStockGUI）

 

4.以可执行文件（.exe）的形式运行

思路：将程序打成jar包，用软件（如j2ewiz）将jar包打成可执行文件（.exe）。其中你需要在软件中设置程序的主入口以及添加依赖的jar包。

界面.bat的脚本如下：

@echo off
if "%OS%" == "Windows_NT" setlocal

rem Make sure prerequisite environment variables are set
if not "%JAVA_HOME%" == "" goto gotJavaHome
echo The JAVA_HOME environment variable is not defined
echo This environment variable is needed to run this program
goto end
:gotJavaHome
if not exist "%JAVA_HOME%\bin\java.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\javaw.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\jdb.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\javac.exe" goto noJavaHome
goto okJavaHome
:noJavaHome
echo The JAVA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program
goto end
