Java执行groovy脚本

 Binding binding = new Binding();
 binding.setVariable("foo", new Integer(2));
 GroovyShell shell = new GroovyShell(binding);

 String script = "import com.myb.to.infrastructure.Md5Util; "
         + "def a = 12; println 'C# md5:' + Md5Util.md5('C#'); "
         + "return foo * a ";
 Object value = shell.evaluate(script);
 System.out.println(value.toString());

 EventDetailTo to = new EventDetailTo();
 to.setId(1);
 to.setTitle("xxxxxx");
 binding = new Binding();
 binding.setVariable("to", to);
 shell = new GroovyShell(binding);
 script = "import com.myb.to.EventDetailTo; "
         + "def getTitle(EventDetailTo to) { return to.getTitle()}; "
         + "getTitle(to)";
