BeanShell 在人工测试与管理中的应用

以下可以实现一个简单的Java Shell:

public class TestInt {

public static void main(String[] args) {

bsh.Interpreter.main(args);

}

}

结果：

BeanShell 2.0b4 - by Pat Niemeyer (pat@pat.net)

bsh % System.out.println("Hello BeanShell");

Hello BeanShell

bsh %

你也可以用以下代码实现同样的功能，代码中可以比较明显地看出其结构：

public static void main(String[] args) {

Reader in = new InputStreamReader( System.in );

PrintStream out = System.out;

PrintStream err = System.err;

boolean interactive = true;;

bsh.Interpreter i = new Interpreter( in, out, err, interactive );

i.run();//线程在这里阻塞读System.in

}

public static void main(String[] args) throws Throwable {

Reader in = new InputStreamReader( System.in );

PrintStream out = System.out;

PrintStream err = System.err;

boolean interactive = true;;

bsh.Interpreter i = new Interpreter( in, out, err, interactive );

Collection theObjectReadyForShellUser = new ArrayList();

theObjectReadyForShellUser.add("Str1");

i.set("myObject", theObjectReadyForShellUser);

i.run();

}

bsh % System.out.println( myObject.get(0) );

Str1

bsh %

public static void main(String[] args) throws Throwable {

Reader in = new InputStreamReader( System.in );

PrintStream out = System.out;

PrintStream err = System.err;

boolean interactive = true;;

bsh.Interpreter i = new Interpreter( in, out, err, interactive );

//show a dialog for user to input command.

String command = JOptionPane.showInputDialog( "Input Command(s)" );

i.eval( command );//Run the command

}
