1.bat 启动java main函数
1.将project导出JAR，过程中注意选择main class
2.新建bat，设置环境变量
3.1启动程序，如果想在黑窗口中打印数字，可以system.out,程序运行万
@echo off @setlocal set JAVA_HOME=jdk1.6.0_25 set PATH=%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin java -jar start.jar或者直接调用class文件
@echo off @setlocal set JAVA_HOME=..\jdk1.6.0_25 set PATH=%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin java usb/CreateStartBat
2.java调用bat
String cmd = "cmd /c start " +
desDisk +
":\\server\\start.bat";
Runtime rt = Runtime.getRuntime();
try {
rt.exec(cmd);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}3.若有需要传参数可以新建文件“xxx.bat”
public static void CreateBat(){
String desDisk = DiskUtil.getDesDisk();
String diskid = System.getProperty("user.dir").split(":")[0];//程序所在盘
System.out.println(desDisk+diskid);
File file = new File(desDisk+"://"+COPY_FOLDER+"//"+FILE_NAME);
FileWriter fw = null;
try {
File file2 = new File(desDisk+"://"+COPY_FOLDER);
if(!file2.exists()){
file2.mkdir();
}
file.createNewFile();
fw = new FileWriter(file);
fw.write("@echo off\r\n");
fw.write("@setlocal\r\n");
fw.write("set JAVA_HOME=" + diskid +":jdk1.6.0_25\r\n");
fw.write(" set PATH=%JAVA_HOME%\\bin;%JAVA_HOME%\\jre\\bin \r\n");
fw.write("echo %~d0\r\n");
fw.write("%~d0\r\n");
fw.write("cd %~dp0\r\n");
fw.write("set JAVA_OPTIONS=%JAVA_OPTIONS% -server\r\n");
fw.write("set JAVA_OPTIONS=%JAVA_OPTIONS% -Xmx512m\r\n");
fw.write("set JAVA_OPTIONS=%JAVA_OPTIONS% -XX:MaxPermSize=128m\r\n");
fw.write("set JAVA_OPTIONS=%JAVA_OPTIONS% -Djava.io.tmpdir=tmp\r\n");
fw.write("set JAVA_OPTIONS=%JAVA_OPTIONS% -Dderby.system.home=derby\r\n");
fw.write("set OSGI_OPTIONS=%OSGI_OPTIONS% -Dosgi.configuration.area=osgi-config\r\n");
fw.write("set OSGI_OPTIONS=%OSGI_OPTIONS% -Dosgi.noShutdown=true\r\n");
fw.write("set OSGI_OPTIONS=%OSGI_OPTIONS% -Dosgi.install.area=./\r\n");
fw.write("echo 启动时JAVA配置: %JAVA_OPTIONS%\r\n");
fw.write("echo 启动时OSGI配置: %OSGI_OPTIONS%\r\n");
fw.write("echo 启动参数: %1 %2 %3 %4\r\n");
fw.write("java %JAVA_OPTIONS% %OSGI_OPTIONS% -jar core/org.eclipse.osgi_3.3.1.R33x_v20070828.jar -clean -consoleLog %1 %2 %3 %4");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
fw.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
