够烦恼的，google下，找到答案了….

Bundle install and the root password

If you don’t want to type the root password for every new project a solution is to move the GEM paths in a directory where the user can write, otherwise a simple solution is to make that folders writable by the user.

赋予权限即可解决：

@Controller  //让该类成为控制器
     public class HelloController {
        
	@RequestMapping(value={"/","/hello"})
	public String hello(int id,Map<String,Object> map) {  //使用Map传值
		System.out.println(id);
		System.out.println("hello");
		map.put("hello", "world");
		return "hello";
	}

1.果然是实践出真知：

public class Hello {

  
	public static  void main(String[] args) throws ClassNotFoundException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
		Class<?> clazz = Class.forName("com.wjch.reflection.Person");	
		Person p = (Person) clazz.newInstance();
 Constructor&gt;[] cons = clazz.getConstructors();

	public function action_authcode() {
	   //随机生成一个4位数的数字验证码
	    $num="";
	    for($i=0;$i<4;$i++){
	    $num .= rand(0,9);
	    }
	   //4位验证码也可以用rand(1000,9999)直接生成
	   //将生成的验证码写入session，备验证页面使用
	    SESSION::put("authcode", $num);
	   //创建图片，定义颜色值

// Use Gists to store code you would like to remember later on
console.log(window); // log the "window" object to the console
